Involved in basal defense against virulent oomycetes. Might be related to the phospholipid scramblase and tubby-like superfamily of membrane tethered transcription factors (By similarity). Limited to discrete pathogen infection sites in leaves. Up-regulated upon infection by oomycetes, but not by bacterial or fungal pathogens. No visible phenotype. Reduced basal and R-protein-mediated disease resistances. Belongs to the LOR family.
