MS2 — Cicer arietinum

Summary

LOC101490782 (CaMS2) on chickpea chromosome 3 encodes a cobalamin-independent methionine synthase, a member of the MetE family. The gene is associated with de novo L-methionine biosynthesis, regulation of starch biosynthesis, and DNA methylation-dependent heterochromatin assembly. It has been linked to responses to oxidative stress, ozone, bacteria, insects, and hypoxia, as well as induced systemic resistance and defense responses involving callose deposition. Associations with whole plant size, seed growth and development, root morphology, salt tolerance, disease tolerance, and stress responses have been noted. Studies of related genes in other species link the family to pollen exine development, male sterility, anther development, and salt tolerance, while research in Arabidopsis and tobacco connects the family to immune responses, pathogen defense, callose deposition, and indolic glucosinolate biosynthesis.
