ENO2 — Beta vulgaris subsp. vulgaris

Summary

BvENO2 (ENO2) on sugar beet chromosome 7 encodes an enolase with phosphopyruvate hydratase activity, also annotated with RNA folding chaperone, SUMO transferase, and DNA binding functions. It is associated with glycolytic and anaerobic respiration processes, cold acclimation, salt and cadmium responses, abscisic acid sensitivity, and sucrose metabolism. The protein localizes to the cytosol, mitochondria, plasmodesma, and apoplast. Associations include leaf length, respiration rate, ethylene sensitivity, stomatal opening, and low temperature stress response. Phenotypic links connect BvENO2 to plant growth, early flowering, altered freezing tolerance, lignin content, drought tolerance, and salt stress tolerance. Studies of related genes in other species link the family to seed size, fatty acid accumulation, pollen development, and immune response.
