LP1 — Sorghum bicolor

Summary

SORBI_3008G030600, designated LP1 (SbLP1) on sorghum chromosome 8, encodes a protein belonging to the plant non-specific lipid-transfer protein (nsLTP) family, with annotated lipid carrier, lipid binding, and chitosan binding activities. The gene is associated with phospholipid transfer to membranes, lipid transport, cutin-based cuticle development, and plant epidermal cell differentiation. It has been linked to grain yield, bacterial blight disease resistance, flowering time, leaf senescence, seed growth and development, abscisic acid sensitivity, stomatal complex closure time, and salt tolerance. The encoded protein localizes to the apoplast, plant-type cell wall, plasmodesmata, and secretory vesicles. Studies of related genes in other species connect the family to cuticle integrity, pathogen resistance, seed set, and stress responses.
