MUM4 — Camelina sativa

Summary

CsMUM4 (CSA14G064070) encodes a protein with UDP-4-keto-6-deoxy-glucose-3,5-epimerase activity, UDP-4-keto-rhamnose-4-keto-reductase activity, UDP-glucose 4,6-dehydratase activity, DTDP-glucose 4,6-dehydratase activity, UDP-L-rhamnose synthase activity, UDP-D-xylose-4-epimerase activity, and UDP-glucose 4-epimerase activity, belonging to the dTDP_Gluc_deHydtase and RmlD-like-bd domain families. This Camelina sativa gene is associated with nucleotide-sugar metabolism, UDP-rhamnose anabolism, UDP-L-arabinose anabolism, mucilage anabolism, galactose metabolism, monosaccharide metabolism, capsule polysaccharide anabolism, and cell wall organization. The encoded protein localizes to the Golgi stack membrane, cytosol, nucleus, and stress granules. CsMUM4 is associated with seed coat mucilage synthesis and composition, seed oil content, rhamnogalacturonan I biosynthesis, root hair development, seed mucilage development, seed coat development, mucilage synthesis, and UDP-rhamnose biosynthesis. Related genes in other species are linked to mucilage biosynthesis and flavonoid glycoside production.
