The receptor-like kinase BIR1 inhibits elicitor-induced plasmodesmata callose deposition and PTI gene expression and requires EDS1 and SOBIR1 to cause dose-dependent cell-death in Arabidopsis
Abstract:The receptor-like kinase BIR1 functions as a negative regulator of cell death and defense in Arabidopsis. Previous studies showed that BIR1 expression is up-regulated during infections with microbes and viruses. However, the biological consequences of BIR1 induction remain unknown. Here, we use a DEX-inducible expression system in Arabidopsis to investigate the outputs associated with physiological and non-physiological levels of BIR1 expression. We show that BIR1 induction at physiological levels significantl… Show more
