SE2 — Pisum sativum

Summary

PSAT6G166120 (SE2, also known as PsACCICER or PsCHITINASE) on garden pea chromosome 6LG2 encodes a protein with a glycosyl hydrolase family 18 catalytic domain, exhibiting chitinase and lysozyme activity and binding calcium ions. The gene is associated with chitin and polysaccharide breakdown, amino sugar metabolism, and protein secretion. It is linked to defence responses, including response to biotic stimulus, defence response to fungi, response to wounding, and cell death. Additional associations include seed germination, seedling development, post-embryonic development, nodulation, and response to cadmium. The encoded protein localises to the amyloplast, vacuole, and extracellular space. The gene is also associated with protein content and root length. Studies of related genes in other species link the family to traits including seed weight, seed hardness, seed dormancy, plant height, biomass yield, root traits, chlorophyll content, drought tolerance, and salt tolerance.
