LP1 — Cicer arietinum

Summary

LOC101503723 (CaLP1, also known as CaATLTP1, CaLTPI-4, CaCDF3, and several LTP designations) on chickpea chromosome 6 encodes a protein belonging to the plant non-specific lipid-transfer protein (nsLTP) family, with bifunctional inhibitor/LTP/seed storage domains. The product exhibits lipid carrier activity, lipid binding, calmodulin binding, calcium ion binding, and protein binding. CaLP1 is associated with phospholipid transfer to membranes, cutin anabolism and cuticle development, lipid transport, plant epidermal cell differentiation, programmed cell death, and responses to salinity, abscisic acid, bacteria, fungi, and mechanical stimulus. It localizes to the apoplast, plant-type cell wall, plasmodesmata, secretory vesicles, Golgi, plastids, and endosomes. The gene is linked to traits including ethylene and abscisic acid sensitivity, jasmonic acid content, stomatal closure, leaf senescence, seed development, flowering time, and salt tolerance. Related genes in other species are associated with yield, nitrogen use efficiency, pathogen resistance, and embryo development.
