PDS — Brassica oleracea

Summary

BoPDS (BOLC102_C04P044010.1) on cabbage chromosome 4 encodes a phytoene desaturase with 9,9'-di-cis-zeta-carotene desaturase and phytoene dehydrogenase activities, binding FAD. The protein localises to plastid membranes, chloroplast thylakoids and envelopes. In cabbage, BoPDS is associated with carotenoid and chlorophyll metabolism, pigmentation, anthocyanin biosynthesis, oviposition, regeneration, response to herbicide, virus-induced post-transcriptional gene silencing, and protein homotetramerization. It has been linked to leaf colour, self-incompatibility, anthocyanin content, and phenotypes including albinism, phytoene desaturation, chlorophyll biosynthesis, and root growth. Studies of related genes in other species connect the family to carotenoid content, photobleaching, drought tolerance, chlorophyll homeostasis, and RNAi silencing efficiency.
