Inductioni

By 2,6-dichloroisonicotinic acid (INA) and salicylic acid (possibly an endogenous signal for acquired resistance). Strongly induced by infection with the bacterial pathogen P.syringae pv. tomato DC3000 (PubMed:1392589). Induced by infection with avirulent and virulent strains of P.syringae pv. maculicola (PubMed:1824335).

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
