Plant genomics on a changing planet

We study the mutational origins of genetic variation in plants at the intersection of evolutionary theory, functional population genomics, and molecular biology.

February 2022

Welcome, Chaehee Lee, a Postdoctoral Researcher who is joining our lab!

January 2022

Paper "Mutation bias reflects natural selection in Arabidopsis thaliana" published in Nature! Here we find evidence that Arabidopsis has a significant reduction in mutation rate in functionally conserved regions of the genome, and evidence that this is mediated by the epigenome. Accompanied by a nice News & Views by Jianzhi Zhang. 


To help understand where this work relates to documented ideas about mutation, we've written a short document On Mutational Randomness, a survey of the view that mutations are random with respect to consequences.

Welcome, Daniela Quiroz, PhD candidate in Integrative Genetics and Genomics who is joining our lab!


September 2021

Welcome to rotating PhD students Matt Davis from Plant Biology and Forrest Li from Integrative Genetics and Genomics!

Paper "Diversity in nonlinear responses to soil moisture shapes evolutionary constraints in Brachypodium" published! Here we combined function-valued trait approaches with quantitative genetic estimates of evolutionary constraint to ask "how do evolutionary constraints change as a function of water availability?"

Book review of "Evolutionary Genetics: Concepts, Analysis, and Practice by Glenn-Peter Sætre and Mark Ravinet" now online. tldr; its a great book!

Our event Catalyzing Adaptive and Resilient Food Systems sponsored by the UC Davis World Food Center and Air Quality Research Center, organized through the Climate Adaptation Research Center was a huge success - over 300 people tuned in from around the world to hear from industry leaders, policymakers, and researchers about developing sustainable agricultural systems in the face of climate change. Looking forward to more events to come. Most of the talks are recorded and can be found on the event page.

UC Davis Land Acknowledgement Statement:

We should take a moment to acknowledge the land on which we are gathered. For thousands of years, this land has been the home of Patwin people. Today, there are three federally recognized Patwin tribes: Cachil DeHe Band of Wintun Indians of the Colusa Indian Community, Kletsel Dehe Wintun Nation, and Yocha Dehe Wintun Nation.

The Patwin people have remained committed to the stewardship of this land over many centuries. It has been cherished and protected, as elders have instructed the young through generations. We are honored and grateful to be here today on their traditional lands.
