Joanne Chory is an American plant biologist and geneticist. Chory is a professor and director of the Plant Molecular and Cellular Biology Laboratory, at the Salk Institute for Biological Studies and an investigator of the Howard Hughes Medical Institute.[1] She holds the Howard H. and Maryam R. Newman Chair in Plant Biology. She is also an adjunct professor in the Section of Cell and Developmental Biology, UC San Diego.[2]


She obtained her bachelor's degree in Biology from Oberlin College, Ohio, and her PhD in Microbiology from the University of Illinois. She was a postdoctoral fellow at the Harvard Medical School in the lab of Frederick M. Ausubel.[3] In 1988 she joined the Salk Institute as an Assistant Professor.

Scientific contributions[edit]

Chory is interested in identifying the mechanisms by which plants respond to changes in their light environment.[9] Light signals are required for the induction and regulation of many developmental processes in plants. She has participated in research dissecting this complex process by isolating mutations that alter light-regulated seedling development in Arabidopsis.[10][11] Her work has identified mutants that are deficient in the phytochrome photoreceptors and in nuclear-localized repressors and has also revealed that steroid hormones control light-regulated seedling development. Dr. Chory's lab has been involved in the manipulation of the biosynthetic pathway for these steroids that altered the growth and development of plants and identification of the putative steroid receptor, a transmembrane receptor kinase.[12] Her group has also contributed towards the understanding of chloroplast to nuclear retrograde signaling [13][14] and plant shade avoidance responses.[15][16]
