PDS — Capsicum annuum

Summary

T459_10988 (PDS) on pepper chromosome 3 encodes a phytoene desaturase, a FAD-binding enzyme with 9,9'-di-cis-zeta-carotene desaturase and phytoene dehydrogenase activities. The gene is associated with carotenoid, isoprenoid, chlorophyll, fatty acid and secondary metabolism, as well as phytoene and carotene anabolism, the pentose-phosphate shunt, N-glycan processing, organelle organization, protein homotetramerization, response to herbicide and stress, and regeneration. It is linked to plastid membrane, chloroplast thylakoid and envelope, and cytosol localization. Traits connected to PDS include fruit and leaf color, anthocyanin and chlorophyll content, photosynthetic and respiration rates, and ethylene sensitivity. Phenotypes associated with the gene encompass phytoene desaturation, chlorophyll biosynthesis, leaf and fruit pigmentation, chilling injury resistance, and lateral root formation and primary root growth.
