Lipid transfer protein involved in seed and ovule maturation and development, probably by regulating the fatty acids homeostasis during suberin and sporopollenin biosynthesis or deposition. Confined to the anthers and stamen of the inflorescence, especially in pollen. In the anthers, specifically expressed in pollen, with levels varying during the different developmental stages. Some early aborted shrunken and deformed seeds, with abnormal hair-like outgrowths, and infertile ovules, and increased salt permeability in seeds associated with an increase in unsubstituted fatty acids but a decrease in omega-hydroxy fatty acids in seed coats. Belongs to the plant LTP family.
