RUBY — Brassica oleracea var. botrytis

Summary

BoRUBY (BOLND125_C07P023520.1_BOLND125_V1) encodes a protein with galactose oxidase and aldehyde oxidase activities, containing glyoxal oxidase N-terminal and galactose oxidase/kelch beta-propeller domains. In cauliflower, this gene is associated with cell wall modification, mucilage extrusion from the seed coat, regeneration, and defence response to fungi. The encoded protein localises to the plant-type cell wall, extracellular region, and cytoplasm. BoRUBY is associated with several seed coat mucilage phenotypes, including suppressed mucilage defects and abnormal seed coat structure, as well as detached epidermal cells. Studies of related genes in other species connect the family to flower colour, cell-to-cell adhesion, pectin composition and cross-linking, and seed coat cell detachment with mucilage extrusion.
