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.

PGEC Greenhouse Manager to Retire

David Hantz, the PGEC greenhouse manager for the last 22 years, is retiring as of Oct. 31, 2014. David was instrumental in expanding the square footage of the greenhouse, initiating a comprehensive Integrated Pest Management Program, procuring upgrades to the greenhouse heating, cooling and control systems, and implementing energy savings by the use of LED lights. David has gone far beyond his job description in maintaining diverse plants and keeping them happy, as well as in training many researchers in safe greenhouse practices. He will be sorely missed by all. Click "Read more" to find out about his retirement plans. Posted 10/15/2014.
