REVERSION-TO-ETHYLENE-SENSITIVITY1 (RTE1) and RTE1-HOMOLOG (RTH)

RTE1 is a novel conserved protein that regulates ETR1 ethylene receptor function. To characterize the function of Arabidopsis RTE1 and its homolog RTH, we are carrying out detailed genetic analyses assisted by the characterization of RTE1 and RTH gene expression patterns. Additional studies are focusing on sub-cellular localization of the RTE1 and RTH proteins in conjunction with protein co-localization and interaction studies with ETR1 and other proteins. We are also analyzing what happens to the ETR1 protein in the rte1 null mutant background.

Project Participants:

• Genetic analyses (Jo Resnick, Maximo Rivarola)
• Gene expression patterns (Ben Maggin)
• Examining ETR1, a putative RTE1 target (Maximo Rivarola)
• Protein localization and co-localization (Chunhai Dong, Maximo Rivarola, Jo Resnick, Nicole Szabo)
