Protein
pEARLI1-like lipid transfer protein 1
Organism
Arabidopsis thaliana
Function
Probable lipid transfer protein (LTP). Seems to control the flowering process and lignin synthesis. Together with DIR1, required for glycerol-3-phosphate- (G3P) and azelaic acid- (AA) induced systemic acquired resistance (SAR). Component of plant systemic immunity involved in priming defenses in a AA-dependent manner, by modulating production and/or translocation of a mobile signal(s) during SAR. Confers resistance to Botrytis cinerea and Pseudomonas syringae pv. tomato DC3000 and PmaDG3. May be involved in induced systemic resistance (ISR) mediated by non-pathogenic bacteria (e.g. P. fluorescens GM30). Prevents electrolyte leakage during freezing damage.
Similarity
Belongs to the plant LTP family. PEARLI1 subfamily.
