CBL — Beta vulgaris subsp. vulgaris

Summary

BvCBL (BVRB_3G062630) on sugar beet chromosome 3 encodes a pyridoxal phosphate-dependent enzyme with cysteine-S-conjugate beta-lyase, cystathionine gamma-synthase, and mimosinase activities, belonging to the Cys/Met metabolism pyridoxal phosphate-dependent transferase family. The gene is associated with transsulfuration, de novo L-methionine biosynthesis, detoxification, and homeostasis, and its product localizes to the chloroplast stroma and cytoplasm. It is linked to salt tolerance and histone methylation. Studies of related genes in other species connect the family to abiotic stress resistance, including drought, cold, osmotic, and heavy metal stress tolerance, as well as methionine biosynthesis, root development, embryo patterning, and traits such as leaf necrosis, potassium uptake, proline and anthocyanin content, water use efficiency, stomatal resistance, chlorophyll content, plant height, and growth.
