RUBY — Brassica oleracea var. botrytis

Summary

BoRUBY (BOLND125_C05P019150.1_BOLND125_V1) on cauliflower chromosome 5 encodes a protein with galactose oxidase and aldehyde oxidase activities, belonging to the glyoxal oxidase N-terminal domain and galactose oxidase/kelch beta-propeller families. The gene is associated with cell wall modification, mucilage extrusion from the seed coat, regeneration, and defence response to fungi. Its product localises to the plant-type cell wall, extracellular region, and cytoplasm. BoRUBY is linked to several seed coat mucilage phenotypes, including suppressed mucilage defects, abnormal seed coat structure, and enhanced extrusion, 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.
