Crops Possibly Protected From Stressors Due To New Discovery
2012-08-31 16:37:30

Salk findings of a key genetic mechanism in plant hormone signaling may help save crops from stress and help address human hunger 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...

  Salk scientists discover 'hidden' code in DNA evolves more rapidly than genetic code A "hidden" code linked to the DNA of plants allows them to develop and pass down new biological traits far more rapidly than previously thought, according to the findings of a groundbreaking study by researchers at the Salk Institute for Biological Studies. The study, published Sept. 16 in the journal Science, provides the first evidence that an organism's "epigenetic" code - an extra layer of...

Salk Institute and Dana Farber Cancer Institute researchers contribute to production of largest-ever map of plant protein interactions 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...

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. What's more, these incompletely or inadequately reprogrammed hotspots are maintained when...

Despite the fact that the human genome sequence lists nearly every single DNA base of the roughly 3 billion bases that make up a human genome, it has remained a biological mystery as to how its function is regulated. Now, scientists from the Salk Institute have revealed the first detailed map of the human epigenome, which is the network of chemical switches that regulates activation of human genes. The human genome was decoded almost 10 years ago, which plainly showed the building blocks of...

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.Finally, after more than a decade of constant probing, a team of researchers led by...
