M2 — Beta vulgaris subsp. vulgaris

Summary

BvM2 (BVRB_9G214560) on sugar beet chromosome 9 encodes a cyclophilin-type peptidylprolyl isomerase (PPIase) with cis-trans proline isomerase activity, and is also annotated for peroxidase activity, salicylic acid binding, and L-serine O-acetyltransferase activity. The gene is associated with diverse biological processes including protein proline isomerization, chaperone-mediated protein complex assembly, alternative mRNA splicing, response to light intensity, and regulation of ARF protein signal transduction. It has been linked to traits such as sucrose content, photosynthetic rate, respiration rate, starch grain synthesis, root mass density, and responses to temperature stress, herbicide sensitivity, and zinc sensitivity. Localization evidence connects the product to the thylakoid lumen, Golgi stack, and proteasome. Related genes in other species are linked to drought response, cold stress tolerance, phototropism, and embryo patterning.
