Prof. Bailey-Serres Receives Two Major Recognitions

Prof. Julia Bailey-Serres, Distinguished Professor of Botany and Plant Sciences and ETOX faculty member, has recently been selected for two major recognitions.  She has been selected by the American Society of Plant Biologists for its 2024 Charles Reid Barnes Life Membership Award, an award for meritorious work in plant biology which provides a life membership in the Society. 

In addition, she has been selected as the 2024 Faculty Research Lecturer at UC Riverside.  This recognition, given to member of the UCR Academic Senate who has made a distinguished record in research, allows the recipient to deliver a lecture to the Academic Senate. It is considered among the highest recognitions given to UCR faculty.  Prof. Bailey-Serres will be presenting her lecture, "Harvesting Genetic Diversity for Resilient Rice" on May 6, 2024 at 2 pm at the Alumni and Visitors Center.  Those interested in attending should RSVP by May 1.  

Our congratulations to Julia for these recent recognitions.

Volatile Chemicals Alter Gene Expression in Fly and Mouse

In lab experiments, Sachiko Haga-Yamanaka, professor of Molecular, Cell and Systems Biology and ETOX faculty member in conjunction with other UCR colleagues including team leader Prof. Anandasankar Ray, exposed fruit flies to diacetyl, a microbial volatile compound released by yeast and common environmental agent, and found changes in gene expression in the fly’s antennae within several days. The team also found similar gene expression changes in the brains of mice and in human cells. The results suggest that the use of volatile chemicals could potentially be developed as a therapeutic approach to treat various diseases. Their results were recently published in the journal eLife and highlighted in UC Riverside News.  Our congratulations to Sachiko, Anand and colleagues for this nice recognition.
