30G — Beta vulgaris subsp. vulgaris

Summary

Bv30G (BVRB_6G136750) on sugar beet chromosome 6 encodes a 14-3-3 domain-containing protein. The gene is associated with RISC complex binding and a wide array of annotated molecular functions including glyceraldehyde-3-phosphate dehydrogenase, xylose isomerase, and fumarate hydratase activities. It is linked to positive regulation of miRNA metabolic processes, activation of syringal lignin anabolism, and fumarate metabolism. Associations with agronomically relevant traits include ferulic acid content, starch grain size, zinc concentration, fruit yield, hexose content, and responses to spot blotch disease and nematode damage. 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 drought sensitivity, tuber sprouting, fungal disease resistance, and seed development.
