Internalization of the peptide signal AtPep1 and its receptors AtPEPR1 and AtPEPR2 and co-receptor BAK1: implications for the plant innate immune responses.

The elicitor peptide "AtPep1" is an endogenous peptide that plays a role in defense aginst pathogens. In Arabidopsis the AtPep1 binds to membrane receptor proteins PEPR1/PEPR2 that in turn interact with the co-receptor BAK1 and subsequently trigger immune responses. This research studies the internalization route of AtPep1 and the subcellular dynamics of its receptors and co-receptor.
