Salk Institute to lead $126 million effort to map the aging human brain
LA JOLLA—With a five-year, $126 million grant from the National Institutes of Health (NIH), a team led by Salk Institute scientists has launched a new Center for Multiomic Human Brain Cell Atlas. Part of the NIH’s Brain Research Through Advancing Innovative Neurotechnologies® (BRAIN) Initiative, the project aims to describe the cells that make up the human brain in unprecedented molecular detail, classify brain cells into more precise subtypes, and pinpoint the location of each cell in the brain. What’s more, the team will track how these features change from early to late life.
How light and temperature work together to affect plant growth
LA JOLLA—Plants lengthen and bend to secure access to sunlight. Despite observing this phenomenon for centuries, scientists do not fully understand it. Now, Salk scientists have discovered that two plant factors—the protein PIF7 and the growth hormone auxin—are the triggers that accelerate growth when plants are shaded by canopy and exposed to warm temperatures at the same time.
The best offense is a great defense for some carnivorous plants
LA JOLLA–Insect-eating plants have fascinated biologists for more than a century, but how plants evolved the ability to capture and consume live prey has largely remained a mystery. Now, Salk scientists, along with collaborators from Washington University in St. Louis, have investigated the molecular basis of plant carnivory and found evidence that it evolved from mechanisms plants use to defend themselves.
Salk Research Professor Todd Michael receives $2 million to build a genome repository for the cassava plant
LA JOLLA–Research Professor Todd Michael will receive nearly $2 million from the Bill & Melinda Gates Foundation to sequence the genomes of multiple lineages of the cassava plant, a large starchy root vegetable also known as yuca root consumed in more than 80 countries around the world. A better understanding of cassava genetics will help researchers and plant breeders develop more productive disease- and drought-resistant plants for the future.
New technology enables unprecedented glimpse inside single brain cells
LA JOLLA—Salk Institute researchers have developed a new genomic technology to simultaneously analyze the DNA, RNA and chromatin—a combination of DNA and protein—from a single cell. The method, which took five years to develop, is an important step forward for large collaborations where multiple teams are working simultaneously to classify thousands of new cell types. The new technology, published in Cell Genomics on March 9, 2022, will help streamline analyses.
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.

The findings shed light on centromere evolution and provides insights into the genomic equivalent of black holes.
Secrets of quillwort photosynthesis could boost crop efficiency
LA JOLLA—The humble quillworts are an ancient group of about 250 small, aquatic plants that have largely been ignored by modern botanists. Now, Salk scientists, along with researchers from the Boyce Thompson Institute, have sequenced the first quillwort genome and uncovered some secrets of the plant’s unique method of photosynthesis—secrets that could eventually lead to the engineering of crops with more efficient water use and carbon capture to address climate change. The findings were published in Nature Communications on November 3, 2021.
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.
