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.

New Collaborative Paper from the Lewis Lab

Graduate student Ilea Chau-Ly and Jenn Lewis collaborated with Joe Bondy-Denomy's lab at UCSF to apply CRISPR-Cas3 gene editing to delete a cluster of effector genes in Pseudomonas syringae. This method will provide a new tool for functional genomics in P. syringae. The paper has been accepted at Nature Methods. Click Read more to read the Abstract. Posted 09/21/2020.

New Graduate Student joins the Lewis Lab

UC Berkeley graduate student Nathan Diplock has joined the Lewis Lab for his dissertation research. He will work on immune pathways regulated by ZAR1. Posted 09/21/2020.

New Paper from the Coleman-Derr Lab

Simmons T. , Styer, A. b., Pierroz, G., Goncalves, A.P., Pasricha, R., Hazra, A.B., Bubner, P. and Coleman-Derr, D. Drought Drives Spatial Variation in the Millet Root Microbiome, Front. Plant Sci., 28 May 2020. The paper explores where shifts in microbiome composition are driven by local or global effects, and compiles results from several other studies for a broad comparison of drought-enriched taxa from different environments and hosts.
