Involved in the resistance to the necrotropic bacteria Erwinia carotovora, probably via negative regulation of auxin signaling. Possesses lipase and antimicrobial activities, inhibiting germination of fungal spores (e.g. Alternaria brassicicola). Expressed seedlings, roots and stems. In roots, by salicylic acid (SA), jasmonic acid (JA), and ethylene (ET) treatments. In glip2, enhanced auxin responses, and higher susceptibility to E.carotovora. Belongs to the 'GDSL' lipolytic enzyme family.
