CBL — Solanum tuberosum

Summary

PGSC0003DMG400029836, designated CBL (StCBL, StCbL) on potato chromosome 10, encodes a pyridoxal phosphate-dependent enzyme with cysteine-S-conjugate β-lyase, cystathionine gamma-synthase, and mimosinase activities (EC 4.4.1.13). The protein localises to the chloroplast stroma and cytoplasm. It is associated with methionine and cysteine biosynthesis, transsulfuration, homocysteine metabolism, sulfate assimilation, and regulation of sulfur metabolism, as well as with TOR signalling, MAPK cascades, oxidative phosphorylation, lignin and sucrose metabolism, and detoxification. The gene has been linked to traits including potassium uptake, proline and anthocyanin content, chlorophyll content, plant height, water use efficiency, stomatal resistance, and salt response. Related genes in other species are linked to abiotic stress resistance, including drought, cold, osmotic, and heavy metal stress tolerance, as well as to embryo patterning and root development.
