SE2 — Beta vulgaris subsp. vulgaris

Summary

BVRB_3G051020 (SE2, also known as CHIB, CHIA, BvSE2, LYS1, BvCHLY, BvCHIB, BvLYS1, CHLY, BvCHIA) on sugar beet chromosome 3 encodes a protein with lysozyme, chitinase and beta-glucosidase activities, belonging to the glycosyl hydrolase 18 family. The gene is associated with chitin and polysaccharide breakdown, amino sugar metabolism, and defence responses to fungi and wounding. It has been linked to seed germination, seedling development, and responses to cold, drought, salinity, and light intensity. The encoded protein localises to the amyloplast, vacuole and extracellular space. SE2 is also associated with bacterial disease resistance. Studies of related genes in other species link the family to traits including carotene and sucrose content, plant height, stem diameter, and tolerance to salt, heat and abiotic stress.
