Short Abstract
The innate pathways of plant immune systems are relatively unknown. Several known proteins contribute to pathogen resistance, but the overall metabolic pathway still remains largely unknown. By piecing together actions of various important proteins in immune response, the pathogen resistance pathways can be better understood. This study focuses on the characterization of a SABP2-interacting protein SIP432. SABP2 is an important protein in plant immunity. BLAST analysis shows that SIP432 is a premnaspirodiene oxygenase-like enzyme. Premnaspirodiene are sesquiterpenes that are enzymatically converted into antimicrobial compounds like solavetivone by hydroxylation. The interaction of SIP432 with tobacco SABP2, a critical component of salicylic acid-mediated plant immunity, implies a role for SIP432 in plant defense signaling. We are taking multiprong approach to understand the role of SIP432. Currently we are checking the changes in the expression of SIP432 in tobacco plants upon pathogen infection and an attempt is being made to clone the gene for biochemical characterization. Discovering the function of SIP432 could help uncover the immunity pathways and pathogen resistance in plants.
