CCD8 — Pisum sativum

Summary

PSAT0S1928G0120, also known as CCD8 or RMS1, encodes a carotenoid cleavage dioxygenase 8 B with 9-cis-10'-apo-beta-carotenal cleavage oxygenase activity. This garden pea gene is associated with strigolactone anabolism, auxin polar transport, and cytokinin anabolism. It has been linked to shoot branching, axillary branching, lateral shoot growth, and secondary shoot formation, as well as root system architecture and stem elongation. The gene is connected to responses to phosphate starvation, nitrogen deficiency, and herbicides, along with leaf senescence, somatic embryogenesis, and shoot regeneration. Localised to the chloroplast stroma, it is also associated with carotenoid and xanthophyll breakdown, abscisic acid anabolism, and exploration behaviour. Studies of related genes in other species link the family to lateral branching, flowering time, and endophytic fungal symbiosis.
