Welcome!
The Whiteman Laboratory is part of the Department of Integrative Biology at the University of California, Berkeley. We study the genomic basis of plant-animal interactions.
The main lab project focuses on understanding how free-living organisms evolve to become parasitic and specialized on a small number of host species and how hosts defend themselves against parasites. An example of a specific question we are addressing is how parasites overcome toxins made by plants, including toxins with broad targets such as mustard oils (e.g., wasabi) and those with specific targets, like cardenolides (e.g., digitoxin). The model system we use includes a parasitic fly in the Drosophila lineage (called Scaptomyza flava) and the genetic model plant Arabidopsis thaliana as a host. Each of these two species has substantial genomic resources, molecular tools and they actually interact in nature. Adult females of S. flava use their cutting ovipositor that serves as both an egg-laying organ and a trophic organ. The egg hatches into a larva, which then creates a mine in the leaf, where it completes development.
A smaller lab project involves the broad-tailed hummingbird (Selasphorus platycercus) at the Rocky Mountain Biological Laboratory (RMBL). We use that system to identify the the genomic architecture underlying variation in foraging traits, and to understand the evolutionary history of those loci. This is a collaborative project with Professor Mary (Cassie) Stoddard at Princeton University and David Inouye at the RMBL
