SMT — Brassica juncea

Summary

BJUUNNG07820S (symbol SMT, also known as BjHMT2) in Indian mustard (Brassica juncea) encodes a homocysteine S-methyltransferase with selenocysteine methyltransferase activity, belonging to the BHMT-like family. The enzyme is localized to the cytosol and cytoplasm and is associated with the S-methylmethionine cycle and methionine biosynthesis. This gene is linked to responses to selenium ion and to seed methionine content. Associations also include chlorophyll content and plant height. Related genes in other species are linked to methionine synthesis and increased seed methionine content.
