What's a GeneRIF?

OCP3 represents a specific control point for callose deposition regulated by jasmonic acid yet ultimately requiring abscisic acid.
Title: Arabidopsis ocp3 mutant reveals a mechanism linking ABA and JA to pathogen-induced callose deposition.
OCP3 may modulate the nucleocytosolic function of NPR1 in the regulation of jasmonic acid-dependent induced defense responses.
Title: OCP3 is an important modulator of NPR1-mediated jasmonic acid-dependent induced defenses in Arabidopsis.
OCP3 plays a pivotal role in the signal pathway controlling drought tolerance through the modulation of ABA-mediated stomatal closure. This function is ABA-dependent but MeJA-independent
Title: Drought tolerance in Arabidopsis is controlled by the OCP3 disease resistance regulator.
OCP3 is an important factor for the COI1-dependent resistance of plants to infection by necrotrophic pathogens.[OCP3]
Title: An Arabidopsis homeodomain transcription factor, OVEREXPRESSOR OF CATIONIC PEROXIDASE 3, mediates resistance to infection by necrotrophic pathogens.
