LP1 — Sorghum bicolor

Summary

SbLP1 (SORBI_3008G030700) on sorghum chromosome 8 encodes a protein with lipid carrier activity, chitosan binding, lipid binding, chitin binding, calmodulin binding, calcium ion binding, protein kinase activity, and ATP binding, belonging to the plant non-specific lipid-transfer protein family. It is associated with phospholipid transfer to membranes, cutin-based cuticle development, lipid transport, seed development, programmed cell death, and responses to chitin and bacterial molecules. The gene has been connected to grain yield, bacterial blight disease resistance, flowering time, leaf senescence, seed growth and development, abscisic acid sensitivity, stomatal closure time, and salt tolerance. It localizes to the apoplast, plant-type cell wall, plasmodesma, secretory vesicle, Golgi, endosome, and plastid. Studies of related genes in other species link the family to drought recovery, pathogen resistance, freezing tolerance, and yield traits.
