aat — Cicer arietinum

Summary

LOC101508851 (symbol aat) on chickpea chromosome 4 encodes a class-IV pyridoxal-phosphate-dependent aminotransferase with L-isoleucine, L-valine, and L-leucine aminotransferase activities. The gene is associated with valine and L-leucine biosynthesis and carboxylic acid metabolism. Its product has been linked to extracellular localization. Associations with seed protein content, protein content, and root length have been noted, as well as a connection to decreased salt stress tolerance. Studies of related genes in other species link the family to drought tolerance and arsenic concentration, though these relationships are not established for chickpea.
