LP2 — Brassica napus

Summary

BnLP2 (LP2) on chromosome C04 of oilseed rape encodes a protein belonging to the plant non-specific lipid-transfer protein (nsLTP) family, with bifunctional inhibitor/LTP/seed storage domains. The gene product is associated with lipid binding and IgE binding molecular functions, and is linked to phospholipid transfer to membranes, pollen wall assembly, pollen tube development, cutin and wax anabolism, cuticle development, and autophagy. It localises to the extracellular region, plasma membrane, cell wall, Golgi, endosome, and TGN. Associations with agronomic traits include seed weight, germination rate, flowering time, and photosynthetic rate. Phenotypic connections observed for this gene include drought and cold tolerance, osmotic stress tolerance, root and flower development, cuticle integrity, and gravitropism. Studies of related genes in other species link the family to yield and nitrogen use efficiency, and to cuticle-cell wall interface integrity.
