Plants rely on the CLASSY gene family to diversify their epigenomes
LA JOLLA—What determines how a cell’s genome is regulated to ensure proper growth and development? Turns out, the parts of the genome that are turned on or off in each cell-type or tissue play a major role in this process. Now, a team at Salk has shown that the CLASSY gene family regulates which parts of the genome are turned off in a tissue-specific manner. The CLASSYs essentially control where the genome is marked by DNA methylation—the addition of methyl chemical groups to the DNA that act like tags saying, “turn off.” Because DNA methylation exists across diverse organisms, including plants and animals, this research has broad implications for both agriculture and medicine. The work, published in Nature Communications on January 11, 2022, identifies the CLSY genes as major factors underlying epigenetic diversity in plant tissues.
Six Salk professors named among most highly cited researchers in the world

This is Tye’s fifth, Shaw’s third and Panda’s first time receiving the designation. Additionally, Ecker appeared in two separate categories: “plant and animal science” and “molecular biology and genetics” and is one of 3.4 percent of researchers selected in two fields. Joseph Nery, a research assistant II in the Ecker lab, was also included on the list.
Call-and-response circuit tells neurons when to grow synapses
LA JOLLA—Brain cells called astrocytes play a key role in helping neurons develop and function properly, but there’s still a lot scientists don’t understand about how astrocytes perform these important jobs. Now, a team of scientists led by Associate Professor Nicola Allen has found one way that neurons and astrocytes work together to form healthy connections called synapses. This insight into normal astrocyte function could help scientists better understand disorders linked to problems with neuronal development, including autism spectrum disorders. The study was published September 8, 2021, in the journal eLife.

Gene identified that will help develop plants to fight climate change
LA JOLLA—Hidden underground networks of plant roots snake through the earth foraging for nutrients and water, similar to a worm searching for food. Yet, the genetic and molecular mechanisms that govern which parts of the soil roots explore remain largely unknown. Now, Salk Institute researchers have discovered a gene that determines whether roots grow deep or shallow in the soil.
New computational tool lets researchers identify cells based on their chromosome shape
LA JOLLA—In the nucleus of every living cell, long strands of DNA are tightly folded into compact chromosomes. Now, thanks to a new computational approach developed at the Salk Institute, researchers can use the architecture of these chromosome folds to differentiate between types of cells. The information about each cell’s chromosome structure will give scientists a better understanding of how interactions between different regions of DNA play a role in health and disease. The study was published in the Proceedings of the National Academy of Sciences the week of July 8, 2019.
Editing of RNA may play a role in chloroplast-to-nucleus communication

Understanding how DNA is selectively tagged with “do not use” marks
LA JOLLA—Not all of your genome needs to be active at any given time. Some regions are prone to hopping around the genome in problematic ways if left unchecked; others code for genes that need to be turned off in certain cells or at certain times. One way that cells keep these genetic elements under control is with the chemical equivalent of a “do not use” sign. This chemical signal, called DNA methylation, is known to vary in different cell types or at different stages of cellular development, but the details of how cells regulate exactly where to put DNA methylation marks have remained unclear.
Self-defense for plants
LA JOLLA—When you see brown spots on otherwise healthy green leaves, you may be witnessing a plant’s immune response as it tries to keep a bacterial infection from spreading. Some plants are more resistant to such infections than others, and plant biologists want to understand why. Salk Institute scientists studying a plant protein called SOBER1 recently discovered one mechanism by which, counterintuitively, plants seem to render themselves less resistant to infection.
Salk scientists Joanne Chory and Terrence Sejnowski named to National Academy of Inventors

Researchers from USC and UC San Diego will also participate in the collaboration.
How plants grow like human brains
LA JOLLA—Plants and brains are more alike than you might think: Salk scientists discovered that the mathematical rules governing how plants grow are similar to how brain cells sprout connections. The new work, published in Current Biology on July 6, 2017, and based on data from 3D laser scanning of plants, suggests there may be universal rules of logic governing branching growth across many biological systems.
New method to rapidly map the “social networks” of proteins
LA JOLLA—Salk scientists have developed a new high-throughput technique to determine which proteins in a cell interact with each other. Mapping this network of interactions, or “interactome,” has been slow going in the past because the number of interactions that could be tested at once was limited. The new approach, published June 26 in Nature Methods, lets researchers test millions of relationships between thousands of proteins in a single experiment.
A better dye job for roots—in plants
LA JOLLA—(June 1, 2017) Once we start coloring our hair, we may be surprised to learn that we begin to have a problem in common with plant biologists: finding the right dye for our roots. In the case of the biologists, just the right chemical is needed to measure exactly how plant roots grow. Now, a researcher at the Salk Institute has discovered a fluorescent dye that, paired with other imaging techniques, reveals root growth to be influenced by a major plant hormone more than previously thought.
Helping plants pump iron
LA JOLLA—Just like people, plants need iron to grow and stay healthy. But some plants are better at getting this essential nutrient from the soil than others. Now, a study led by a researcher at the Salk Institute has found that variants of a single gene can largely determine a plant’s ability to thrive in environments where iron is scarce.
Finding our way around DNA
LA JOLLA—Most of us would be lost without Google maps or similar route-guidance technologies. And when those mapping tools include additional data about traffic or weather, we can navigate even more effectively. For scientists who navigate the mammalian genome to better understand genetic causes of disease, combining various types of data sets makes finding their way easier, too.
Building a better brain
LA JOLLA—When you build models, whether ships or cars, you want them to be as much like the real deal as possible. This quality is even more crucial for building model organs, because disease treatments developed from these models have to be safe and effective for humans. Now, scientists at the Salk Institute have studied a 3D “mini-brain” grown from human stem cells and found it to be structurally and functionally more similar to real brains than the 2D models in widespread use. The discovery, appearing in the December 20, 2016, issue of Cell Reports, indicates that the new model could better help scientists understand brain development as well as neurological diseases like Alzheimer’s or schizophrenia.

Gauging stem cells for regenerative medicine
LA JOLLA—Salk scientists and colleagues have proposed new molecular criteria for judging just how close any line of laboratory-generated stem cells comes to mimicking embryonic cells seen in the very earliest stages of human development, known as naïve stem cells. The tests found that no current protocols lead to truly naïve stem cells, but the guidelines may help researchers achieve that goal by pointing out where each current method falls short. Generating naïve stem cells would be a boon to both basic research and to medical applications of stem cells, such as growing tissue for organ replacement.
Salk researchers chart landscape of genetic and epigenetic regulation in plants
LA JOLLA—A new technique developed by Salk Institute scientists for rapidly mapping regions of DNA targeted by regulatory proteins could give scientists insight into what makes some plants drought tolerant or disease resistant, among other traits.

Unique epigenomic code identified during human brain development
LA JOLLA,CA—Changes in the epigenome, including chemical modifications of DNA, can act as an extra layer of information in the genome, and are thought to play a role in learning and memory, as well as in age-related cognitive decline. The results of a new study by scientists at the Salk Institute for Biological Studies show that the landscape of DNA methylation, a particular type of epigenomic modification, is highly dynamic in brain cells during the transition from birth to adulthood, helping to understand how information in the genomes of cells in the brain is controlled from fetal development to adulthood. The brain is much more complex than all other organs in the body and this discovery opens the door to a deeper understanding of how the intricate patterns of connectivity in the brain are formed.
Scientists identify thousands of plant genes activated by ethylene gas
LA JOLLA, CA—It’s common wisdom that one rotten apple in a barrel spoils all the other apples, and that an apple ripens a green banana if they are put together in a paper bag. Ways to ripen, or spoil, fruit have been known for thousands of years-as the Bible can attest-but now the genes underlying these phenomena of nature have been revealed.
Smoke signals: How burning plants tell seeds to rise from the ashes
LA JOLLA, CA—In the spring following a forest fire, trees that survived the blaze explode in new growth and plants sprout in abundance from the scorched earth. For centuries, it was a mystery how seeds, some long dormant in the soil, knew to push through the ashes to regenerate the burned forest.
Hidden layer of genome unveils how plants may adapt to environments throughout the world
LA JOLLA, CA—Scientists at the Salk Institute for Biological Studies have identified patterns of epigenomic diversity that not only allow plants to adapt to various environments, but could also benefit crop production and the study of human diseases.
Plants cut the mustard for basic discoveries in metabolism
LA JOLLA, CA—You might think you have nothing in common with mustard except hotdogs. Yet based on research in a plant from the mustard family, Salk scientists have discovered a possible explanation for how organisms, including humans, directly regulate chemical reactions that quickly adjust the growth of organs. These findings overturn conventional views of how different body parts coordinate their growth, shedding light on the development of more productive plants and new therapies for metabolic diseases.
More than 3,000 epigenetic switches control daily liver cycles
LA JOLLA, CA—When it’s dark, and we start to fall asleep, most of us think we’re tired because our bodies need rest. Yet circadian rhythms affect our bodies not just on a global scale, but at the level of individual organs, and even genes.
Two more Salk scientists elected as AAAS Fellows
LA JOLLA,CA—Salk faculty members Joseph Ecker and Joseph Noel have been named as 2012 Fellows by the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society and the publisher of the journal Science. Election as an AAAS Fellow is among the highest honors in American science and scholars are selected by their peers for “scientifically or socially distinguished efforts to advance science or its applications,” according to election administrators.
Discovery may help protect crops from stressors
LA JOLLA, CA—Scientists at the Salk Institute for Biological Studies have discovered a key genetic switch by which plants control their response to ethylene gas, a natural plant hormone best known for its ability to ripen fruit, but which, under stress conditions, can cause wilted leaves, premature aging and spoilage from over-ripening. The findings, published August 30 in Science magazine, may hold the key to manipulating plants’ ethylene on/off switch, allowing them to balance between drought resistance and growth and, therefore, decrease crop losses from drought conditions.
Planting the seeds of defense
LA JOLLA, CA—It was long thought that methylation, a crucial part of normal organism development, was a static modification of DNA that could not be altered by environmental conditions. New findings by researchers at the Salk Institute for Biological Studies, however, suggest that the DNA of organisms exposed to stress undergo changes in DNA methylation patterns that alter how genes are regulated.
Salk scientists discover how plants grow to escape shade
LA JOLLA, CA—Mild mannered though they seem, plants are extremely competitive, especially when it comes to getting their fair share of sunlight. Whether a forest or a farm, where plants grow a battle rages for the sun’s rays.

Scientists take a giant step for people – with plants!
La Jolla—Science usually progresses in small steps, but on rare occasions, a new combination of research expertise and cutting-edge technology produces a ‘great leap forward.’ An international team of scientists, whose senior investigators include Salk Institute plant biologist Joseph Ecker, report one such leap in the July 29, 2011 issue of Science. They describe their mapping and early analyses of thousands of protein-to-protein interactions within the cells of Arabidopsis thaliana -a variety of mustard plant that is to plant biology what the lab mouse is to human biology.
Salk scientist Joseph Ecker, appointed as Howard Hughes Medical Institute and Gordon and Betty Moore Foundation Investigator
La Jolla—Plant biologist Joseph R. Ecker, Ph.D., professor and director of the Genomic Analysis Laboratory at the Salk Institute for Biological Studies, has been selected for a prestigious position as an investigator of the Howard Hughes Medical Institute (HHMI) and the Gordon and Betty Moore Foundation (GBMF).
Plant receptors reflect different solutions for signaling problem
La Jolla—Birds do it, bees do it, and for most things biological, even plants do it. But not necessarily like their animal counterparts. A study led by Salk Institute scientists shows that a plant receptor does one of the most fundamental cellular “its”—the delivery of a hormonal signal from outside the cell to the nucleus—in a radically different way than its animal cousins. Knowing that could aid creation of techniques to speed plant growth and enhance agricultural production.
Salk professor, Joanne Chory, elected to Royal Society
LA JOLLA, CA—The Royal Society announced today that Salk Institute molecular biologist Joanne Chory, Ph.D., an expert on how plants regulate their growth, has been named a foreign member of the Royal Society, the world’s oldest scientific academy in continuous existence. She is being recognized as “a beacon of scientific excellence and relentless ambassador for plant research in the international community.”
Cell reprogramming leaves a “footprint” behind
LA JOLLA, CA—Reprogramming adult cells to recapture their youthful “can-do-it-all” attitude appears to leave an indelible mark, found researchers at the Salk Institute for Biological Studies. When the team, led by Joseph Ecker, PhD., a professor in the Genomic Analysis Laboratory, scoured the epigenomes of so-called induced pluripotent stem cells base by base, they found a consistent pattern of reprogramming errors.
Different evolutionary paths lead plants and animals to the same crossroads: tyrosine phosphorylation
LA JOLLA, CA—In analyzing the molecular sensor for the plant growth hormone brassinolide, researchers at the Salk Institute for Biological Studies discovered that although plants took an evolutionary path different from their animal cousins, they arrived at similar solutions to a common problem: How to reliably receive and process incoming signals.
Connecting the dots: How light receptors get their message across
LA JOLLA, CA—For a plant, light is life. It drives everything from photosynthesis to growth and reproduction. Yet the chain of molecular events that enables light signals to control gene activity and ultimately a plant’s architecture had remained in the dark. Now a team of researchers from the Salk Institute for Biological Studies and Duke University have identified the courier that gives the signal to revamp the plant’s gene expression pattern after photoreceptors have been activated by light.
What drives our genes? Salk researchers map the first complete human epigenome
LA JOLLA, CA—Although the human genome sequence faithfully lists (almost) every single DNA base of the roughly 3 billion bases that make up a human genome, it doesn’t tell biologists much about how its function is regulated. Now, researchers at the Salk Institute provide the first detailed map of the human epigenome, the layer of genetic control beyond the regulation inherent in the sequence of the genes themselves.
Light or fight? Scientists discover how plants make tough survival choices
La Jolla, CA — Ever since insects developed a taste for vegetation, plants have faced the same dilemma: use limited resources to out-compete their neighbors for light to grow, or, invest directly in defense against hungry insects. Now, an international team of scientists at the Salk Institute for Biological Studies and the Institute of Investigaciones Fisiológicas y Ecológicas Vinculadas a la Agronomía (IFEVA) has discovered how plants weigh the tradeoffs and redirect their energies accordingly.
Why fruits ripen and flowers die: Salk scientists discover how key plant hormone is triggered
La Jolla, CA—Best known for its effects on fruit ripening and flower fading, the gaseous plant hormone ethylene shortens the shelf life of many fruits and plants by putting their physiology on fast-forward. In recent years, scientists learned a lot about the different components that transmit ethylene signals inside cells. But a central regulator of ethylene responses, a protein known as EIN2, resisted all their efforts.
Biologists Identify Genes Controlling Rhythmic Plant Growth
La Jolla, CA – A team of biologists from the Salk Institute for Biological Studies, UC San Diego, and Oregon State University has identified the genes that enable plants to undergo bursts of rhythmic growth at night and allow them to compete when their leaves are shaded by other plants.
Not your grandfather’s transcriptome-plant biologists discover unexpected proteins affecting small RNAs
La Jolla, CA – Now that high school biology students can recite that genes are made of DNA, which is transcribed into messenger RNA (mRNA), which is then translated into protein, along comes a new class of molecules, sending students-and many scientists-scrambling for updated textbooks.
Charting the Epigenome
La Jolla, CA – Until recently, the chemical marks littering the DNA inside our cells like trees dotting a landscape could only be studied one gene at a time. But new high-throughput DNA sequencing technology has enabled researchers at the Salk Institute for Biological Studies to map the precise position of these individual DNA modifications throughout the genome of the plant Arabidopsis thaliana, and chart its effect on the activity of any of Arabidopsis‘ roughly 26,000 genes.
A place in the sun
La Jolla, CA – Those spindly plants that desperately try to reach for a break in the canopy formed by larger plants all suffer from the same affliction: Shade avoidance syndrome or SAS. Now, the molecular details of SAS have been brought to light by researchers at the Salk Institute for Biological Studies.
New plant study reveals a “deeply hidden” layer of the transcriptome
La Jolla, CA – Cells keep a close watch over the transcriptome – the totality of all parts of the genome that are expressed in any given cell at any given time. Researchers at the Salk Institute for Biological Studies and the University of Missouri-Kansas City teamed up to peel back another layer of transcriptional regulation and gain new insight into how genomes work.
Charting ever-changing genomes
La Jolla, CA – Instead of immutable proprietary software, any species’ genetic information resembles open source code that is constantly tweaked and optimized to meet the users’ specific needs. But which parts of the code have withstood the test of time and which parts have undergone rapid evolutionary change has been difficult to assess.
All roads lead to GUN1
La Jolla, CA – Scientists have identified three different signals that indicate damage to chloroplasts – the photosynthetic factories of plant cells that give plants their green color – but little is known about how the signal gets passed on to the nucleus. Scientists at the Salk Institute for Biological Studies made a big step towards explaining how chloroplasts let a cell’s nucleus know when things start to go wrong at the periphery so nuclear gene expression can be adjusted accordingly.
Plant size morphs dramatically as scientists tinker with outer layer
La Jolla, CA – Jack’s magical beans may have produced beanstalks that grew and grew into the sky, but something about normal, run-of-the-mill plants limits their reach upward. For more than a century, scientists have tried to find out which part of the plant both drives and curbs growth: is it a shoot’s outer waxy layer? Its inner layer studded with chloroplasts? Or the vascular system that moves nutrients and water? The answer could have great implications for modern agriculture, which desires a modern magical bean or two.
National Academy of Sciences honors Joe Ecker with Carty Award
La Jolla, CA – The National Academy of Sciences has selected Joseph R. Ecker, professor in the Plant Biology Laboratory and director of the Salk Institute Genomic Analysis Laboratory, to receive the 2007 John J. Carty Award for the Advancement of Science “for contributions in the areas of ethylene signal transduction and Arabidopsis genomics that have paved the way for a revolution in modern agriculture.”
In a technical tour de force, Salk scientists take a global view of the epigenome
La Jolla, CA – A collaboration between researchers at the Salk Institute for Biological Studies and the University of California at Los Angeles captured the genome-wide DNA methylation pattern of the plant Arabidopsis thaliana – the “laboratory rat” of the plant world – in one big sweep.
Computational analysis shows that plant hormones often go it alone
La Jolla, CA – Unlike the Three Musketeers who lived by the motto “All for one, one for all,” plant hormones prefer to do their own thing. For years, debate swirled around whether pathways activated by growth-regulating plant hormones converge on a central growth regulatory module. Now, the cooperation model is challenged by researchers at the Salk Institute for Biological Studies. They show that each hormone acts largely independently in the Aug. 11 issue of Cell.
Salk scientists untangle steroid hormone signaling in plants
La Jolla, CA – When given extra shots of the plant steroid brassinolide, plants “pump up” like major league baseball players do on steroids. Tracing brassinolide’s signal deep into the cell’s nucleus, researchers at the Salk Institute for Biological Studies have unraveled how the growth-boosting hormone accomplishes its job at the molecular level.
Salk scientist Joe Ecker elected to National Academy of Sciences
La Jolla, CA – Salk Institute professor Joseph R. Ecker, who spearheaded the first effort to decipher a plant genome, has been elected a member of the National Academy of Sciences. The Academy made the announcement today during its 143rd annual meeting in Washington, DC. Election to the Academy recognizes distinguished and continuing achievements in original research, and is considered one of the highest honors accorded a U.S. scientist.
Salk Institute plant biologist named AAAS Fellow
La Jolla, CA – Salk Institute molecular biologist Joanne Chory, Ph.D., an expert on how plants regulate their growth, has been elected a Fellow of the world’s largest general scientific society, the American Association for the Advancement of Science (AAAS).
Plant Hormone Discovery Offers Potentially Increased Crop Yield
La Jolla, CA – Scientists at the Salk Institute for Biological Studies have filled in two significant gaps in the molecular pathway that allow plant steroid hormones to stimulate plants to be larger and more fruitful. The findings may open up the prospect of larger vegetables or increased seed yield and could have a galvanizing effect on agricultural research.
Gene Chip Study Could Lead to New Hybrid Plants
La Jolla, CA – A study led by the Salk Institute and the University of California at Berkeley has found new methods to identify functional genes in the common mustard weed Arabidopsis. This technology may lead to the development of new ways to modify plants to grow faster, produce more food and resist disease.
Salk Study Advances Understanding of Plant Genes and Their Function
La Jolla, CA – A Salk Institute study provides significant new information in the process of allowing scientists to understand the function of plant genes. The study is published in the August 1 issue of Science.
Salk Scientists Identify Pathway That Determines When Plants Flower
La Jolla, CA – Salk scientists have defined a new pathway that controls how plants flower in response to shaded, crowded conditions, and their findings may have implications for increasing yield in crops ranging from rice to wheat.
