CBL — Solanum tuberosum

Summary

PGSC0003DMG400001884 (CBL) on potato chromosome 4 encodes a cystathionine beta-lyase, a pyridoxal phosphate-dependent enzyme with cysteine-S-conjugate beta-lyase and carbon-sulfur lyase activities. The gene is associated with transsulfuration, de novo L-methionine biosynthesis, TOR signaling, stomatal closure, virus-induced PTGS, response to salt, regulation of gene expression, and homeostasis. It has been linked to potassium uptake, proline content, water use efficiency, stomatal resistance, plant height, and plant growth and development traits, as well as histone methylation. The encoded protein localizes to the chloroplast stroma and cytoplasm. Studies of related genes in other species link the family to abiotic stress resistance, heavy metal stress tolerance, drought tolerance, cold stress tolerance, osmotic stress tolerance, root development, embryo patterning, and traits including leaf necrosis, auxin content, salt response, anthocyanin content, chlorophyll content, and low temperature stress response.
