SMT — Brassica juncea

Summary

BJUB06G06590S (symbol SMT, preferred name BjHMT2) encodes a homocysteine S-methyltransferase with selenocysteine methyltransferase activity, belonging to the BHMT-like family. It is localized to the cytosol and cytoplasm. The gene is associated with the S-methylmethionine cycle and methionine biosynthesis, and has been linked to responses to selenium ion. Associations with chlorophyll content and plant height have been recorded, and the gene is connected to seed methionine content. Studies of related genes in other species link the family to methionine synthesis and increased seed methionine content.
