Protein: GDSL esterase/lipase 1 (EC 3.1.1.-) (Extracellular lipase 1) (Q9FLN0)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Confers resistance to the necrotrophic fungus Alternaria brassicicola. Possesses lipase and antimicrobial activities that directly disrupt fungal spore integrity. Triggers systemic resistance, mostly by the ethylene-dependent pathway.
Subcellular location: Secreted {ECO:0000269|PubMed:16126835}. Note=Secreted upon salicylic acid treatment. {ECO:0000269|PubMed:16126835}.
