arabidopsisThe Plant Gene Expression Center (PGEC) conducts fundamental research in plant molecular biology. Researchers are elucidating the signal transduction pathways responsible for the perception of environmental and cellular cues. We are exploring disease resistance, light perception, the circadian clock, vegetative growth and the plant-associated microbiome. Essential genes and the networks within which they operate are elucidated using molecular, genetic and biochemical approaches.

The PGEC is a collaboration of the Agricultural Research Service of the U.S. Department of Agriculture and the Plant & Microbial Biology Department of the University of California, Berkeley. The Center's principal investigators are faculty at UC Berkeley, and research opportunities are available in our laboratories for graduate and undergraduate students.

Devin Coleman-Derr named Early Career Research Scientist in USDA/ARS

Quail Lab Paper Published in Nature Communications

Plants monitor their light environment through photoreceptors in that include phytochromes. Transcription factors called PIFs (for phytochrome interacting factors) were known to be phosphorylated as part of the light signaling cascade, but the kinases responsible for this phosphorylation were unknown. Ni et al. (2017) have now identified the responsible kinases. Click "Read more" to read the abstract, and for a link to the publication (open access). Posted 09/18/2017.

Coleman-Derr Lab Awarded Grant from The Conservation, Food & Health Foundation

Cassava is considered one of the world’s five major food crops, vital to the food security of more than half a billion people around the globe. While cassava is resistant to drought and pests, pathogens represent an Achilles Heel for an otherwise hearty crop.The Coleman-Derr lab was awarded $20,000, over two years. They will use metagenomics to investigate the effect of agronomic methods on Cassava health in Uganda. Click "Read more" for details and for a link to the Foundation's Website. Posted 06/01/2017.

Lewis Lab News - New Postdoc, New Publication

Dr. Yuan Chen, previously in the McCormick lab, has joined the Lewis Lab as a postdoctoral fellow. Yuan will investigate immune responses in Brachypodium distachyon, a model grass species, to Pseudomonas syringae infection. Jana Hassan developed a seedling-based assay to assess resistance to Pseudomonas syringae in tomato: Hassan, Jana A., Zhou, Yan-Ming Jane, and Lewis, Jennifer D. (2017). A rapid seedling resistance assay identifies wild tomato lines that are resistant to Pseudomonas syringae pv. tomato race 1. Molecular Plant-Microbe Interactions; posted online on 18 May 2017.
