Walker Named Gilgut Professor

Elsbeth Walker’s main area of research focuses on understanding the fundamental mechanisms underlying iron homeostasis in plants, which can set the foundation for increasing available iron in food crops. Her work on this subject began with the identification of Yellow Stripe1 (YS1), which encodes the iron-phytosiderophore transporter that is responsible for primary iron uptake in grass species. Subsequently, her group investigated the related family of proteins, YELLOW STRIPE1-LIKEs (YSLs), and demonstrated their involvement in the long distance movement of metals in plants. She is keenly interested in uncovering additional features of both the iron uptake, and long distance iron movement pathways. Elsbeth has more recently begun to investigate the genetic basis of taxol biosynthesis using cultured Taxus cells, using transcriptome analyses. She hopes that this effort will enable cheaper and more efficient production of this important anti-cancer drug.

Elsbeth is an enthusiastic teacher, and developed the popular course, Gene and Genome Analysis, an intensive lab experience that gives students the chance to develop both computer assisted bioinformatics skills as well as ‘wet lab’ molecular biology skills. She has directed the Plant Biology Graduate program for the past several years, coordinating close to 40 faculty from five campus departments into a program that currently enrolls 20 PhD students.
