Abstract: The Howe laboratory uses genetic, biochemical, and molecular approaches to address the regulatory basis of induced plant defense responses to herbivory and wound stress. As a highly dynamic form of plant immunity, the wound response confers systemic resistance to a broad spectrum of plant consumers, ranging from microbes to mammals. Research in the Howe lab has employed tomato and Arabidopsis as model systems to identify genes involved in the biosynthesis and perception of the lipid-derived signal jasmonate. These studies helped to establish the paradigm of jasmonate as a hormone signal for modulating plant interactions with other organisms. Their lab has also contributed to the understanding of key steps in the jasmonate signaling pathway, including the discovery of JAZ transcriptional repressor proteins, identification of jasmonoyl-isoleucine as the receptor-active form of the signal, and characterization of the jasmonate co-receptor complex. Their most recent work seeks to elucidate mechanisms to attenuate jasmonate responses as a basis to understand tradeoffs between growth and defense.
