GSA — Triticum turgidum subsp. durum

Summary

TRITD7BV1G077550 (symbol TtGSA) on durum wheat chromosome 7B encodes a chloroplastic glutamate-1-semialdehyde 2,1-aminomutase (EC 5.4.3.8), a pyridoxal phosphate-dependent enzyme. The gene is associated with chlorophyll biosynthesis and content, porphyrin-containing compound biosynthesis, and biotin, arginine, proline and alkaloid anabolism. It has been linked to leaf vein morphology, vascular tissue pattern formation, phloem transport, and responses to flooding, oxidative stress, brassinosteroid and jasmonic acid. Associations with plant growth, shoot development, premature senescence and leaf cell death have also been noted. Studies of related genes in other species connect the family to chlorophyll biosynthesis and shoot development.
