Protein
Probable serine/threonine-protein kinase PBL1
Gene
PBL1
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Contributes to pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) signaling, including calcium signaling and root growth inhibition, and defense responses downstream of FLS2 (PubMed:20413097, PubMed:25522736). Acts additively with BIK1 in PTI defenses (PubMed:20413097, PubMed:25522736). Seems not required for flg22-induced MAPK activation (Probable). Required for Pep1-induced defenses (PubMed:25522736). Pep1 is an endogenous elicitor that potentiates PAMP-inducible plant responses (PubMed:23431184, PubMed:25522736).1 Publication3 Publications

Disruption phenotypei
No visible phenotype under normal growth conditions (PubMed:20413097). Abrogated kinase activity (PubMed:25522736). In cce5-2 and cce5-4, reduced calcium levels after elicitation with peptides representing bacteria-derived microbe- and damage-associated molecular patterns (MAMPs, flg22 and elf18, and the endogenous DAMP AtPep1), but normal response to chitin octamers. Reduced root growth inhibition response to flg22 (PubMed:25522736).2 Publications
