ROC3 — Brassica oleracea

Summary

BoROC3 (ROC3) on cabbage chromosome 9 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with cis-trans proline isomerase activity and cyclosporin A binding. It also shows DNA binding transcription factor activity, protein binding, and chromatin binding. The gene is associated with sex differentiation, estrogen anabolism, spermatogenesis, guard cell fate commitment, and responses to salt, mannitol, and low humidity. It has been linked to heterosis, flowering time, plant growth and development, abiotic stress response, oxidative stress response, abscisic acid sensitivity, and traits including salt tolerance, drought stress response, pathogen resistance, and wound response. Localisation evidence connects the product to the cytosol, chloroplast stroma, nucleolus, plasmodesma, stress granule, and mitochondria. Studies of related genes in other species link the family to stomatal development, drought response, basal immunity, and chromatin structure.
