RPB2 — Beta vulgaris subsp. vulgaris

Summary

BvRPB2 (BVRB_8G183220) on sugar beet chromosome 8 encodes a protein with DNA-directed RNA polymerase activity, ribonucleoside binding, and zinc-binding capacity, and contains RNA polymerase Rpb2 domains. The product localises to the RNA polymerase II core complex and nucleus. This gene is associated with transcription elongation from Pol II promoters, miRNA processing, RNA-dependent gene silencing, and responses to glucose and salinity. It is linked to traits including herbicide sensitivity, root meristem development, leaf composition, low temperature stress response, and plant growth and development. Associations with root development, stem cell niche maintenance, seed size, leaf size, sugar and starch accumulation, and freezing tolerance have been reported. Related genes in other species are linked to responses to multiple hormones, stress, and miRNA accumulation.
