30G — Beta vulgaris subsp. vulgaris

Summary

Bv30G (BVRB_6G138550) on sugar beet chromosome 6 encodes a 14-3-3 domain-containing protein. The gene is associated with RISC complex binding and numerous enzyme activities including glyceraldehyde-3-phosphate dehydrogenase, xylose isomerase, and fumarate hydratase activities. It has been linked to diverse biological processes such as positive regulation of miRNA metabolic processes, activation of syringal lignin anabolism, fumarate metabolism, and non-photoreactive DNA repair. Associations with agronomically relevant traits include ferulic acid content, starch grain size, zinc content, fruit yield, hexose content, and spot blotch response. The gene is also connected to iron-deficiency response, low phosphorus stress tolerance, root growth under alkaline stress, and immunity-associated programmed cell death. Studies of related genes in other species link the family to seed development, pathogen response, drought sensitivity, and tuber sprouting.
