CHLM — Brassica oleracea

Summary

BoCHLM (BOLC102_C01P021740.1_BOLC102_V1) on cabbage chromosome 1 encodes a magnesium-protoporphyrin O-methyltransferase, a SAM-dependent methyltransferase family protein with a Mg_prot_MeTrfase domain. The gene is associated with chlorophyll metabolism, including both anabolism and breakdown, and with anthocyanin anabolism, sumoylation, and NO storage. It has been linked to chlorophyll content and flowering time traits. The product localises to the chloroplast thylakoid membrane, envelope, cytosol, and nucleus. Studies of related genes in other species connect the family to chlorophyll biosynthesis, photosynthesis-associated nuclear gene expression, stomatal aperture, ABA sensitivity, drought tolerance, and leaf temperature, as well as immune response in tomato.
