VQ9 — Beta vulgaris subsp. vulgaris

Summary

BvVQ9 (BVRB_5G105910) on sugar beet chromosome 5 encodes a VQ-domain-containing protein with transcription cis-regulatory region binding, DNA binding transcription factor activity, and protein binding. This gene is associated with regulation of seed size, endosperm development, cellular responses to heat, hydrogen peroxide, hypoxia, and UV-B, systemic acquired resistance, JA signaling, camalexin anabolism, and antiviral response. Associations with agronomically relevant traits include submergence tolerance, salinity stress tolerance, high temperature stress response, disease tolerance, shoot axis branching, root development, leaf senescence, and seedling growth. The gene is also linked to cellular sodium and potassium ion homeostasis, cell wall modification, and positive regulation of autophagy. Related genes in other species link the VQ family to seed size and endosperm growth.
