ZDS — Brassica oleracea

Summary

BoZDS (BOLC102_C05P066010.1) on cabbage chromosome 5 encodes a protein with zeta-carotene desaturase domains, 9,9'-di-cis-zeta-carotene desaturase and phytoene dehydrogenase activities, FAD binding, and redox activity. The gene is associated with carotenoid, carotene and lycopene anabolism, as well as response to herbicide and protein homotetramerization. Its product localises to the chloroplast thylakoid, chloroplast envelope and membrane. BoZDS is associated with chloroplast development, photoprotection, plant growth and development, abscisic acid biosynthesis, retrograde signalling and leaf development. Studies of related genes in other species link the family to carotenoid biosynthesis and Pigment Defective Embryo, while sequence similarity associations connect the family to flower colour, leaf colour, carotenoid content, transpiration rate, stomatal resistance, chlorophyll content, photochemical quenching and root morphology traits.
