MUM4 — Camelina sativa

Summary

CsMUM4 (CSA03G060770) on Camelina sativa chromosome 3 encodes a protein with UDP-glucose 4,6-dehydratase, UDP-4-keto-6-deoxy-glucose-3,5-epimerase, UDP-4-keto-rhamnose-4-keto-reductase, UDP-L-rhamnose synthase, UDP-D-xylose-4-epimerase, and UDP-glucose 4-epimerase activities, belonging to the dTDP-glucose dehydratase and RmlD-like binding domain families. The gene is associated with UDP-rhamnose, UDP-L-arabinose, and mucilage anabolism, cell wall organization, and galactose metabolism, and localizes to the Golgi stack membrane, cytosol, nucleus, and stress granules. CsMUM4 is associated with seed coat mucilage synthesis and development, seed oil content, rhamnogalacturonan I biosynthesis, root hair development, and seed mucilage composition. Related genes in other species are linked to mucilage biosynthesis and flavonoid glycoside production.
