LP1 — Sorghum bicolor

Summary

SbLP1 (SORBI_3008G031000) on sorghum chromosome 8 encodes a protein with lipid carrier activity, chitosan and chitin binding, calcium ion binding, calmodulin binding, and protein serine/threonine kinase activity, and belongs to the plant non-specific lipid-transfer protein family. The gene is associated with lipid transport, phospholipid transfer to membranes, cutin-based cuticle development, seed development, programmed cell death, and responses to chitin and bacterial molecules. It has been linked to grain yield, bacterial blight disease resistance, flowering time, leaf senescence, seed growth and development, abscisic acid sensitivity, stomatal closure, and salt tolerance. Additional associations include seedling growth, cuticle permeability, gravitropism, pollen tube growth, shoot branching, osmotic stress tolerance, and freezing tolerance. Studies of related genes in other species connect the family to drought recovery, pathogen resistance, yield, and nitrogen use efficiency.
