CPN60 — Beta vulgaris subsp. vulgaris

Summary

BvCPN60 (BVRB_002330) on sugar beet chromosome 0073.scaffold00248 encodes a chaperonin of the Cpn60/GroEL family with ATP-dependent protein folding chaperone activity, ATPase, RNA and copper binding functions. The gene is associated with protein folding, refolding, chaperone-mediated protein complex assembly, group II intron splicing, mitochondrial biogenesis, cell death, programmed cell death and response to heat. It localises to the mitochondrial lumen, cytosol, chloroplast envelope and stroma, ER, plant-type vacuole and cytosolic ribosome. BvCPN60 is associated with cytoplasmic male sterility, heat stress tolerance and plant stature. Studies of related genes in other species link the family to protein content, chlorophyll content, plant height, root length and morphology, and tolerance to drought, high temperature and oxidative stress.
