DHNS — Capsicum annuum

Summary

CaDHNS (T459_33283) on pepper chromosome PGAv.1.6.scaffold1110 encodes a DHNA-CoA synthase (MenB family) with enoyl-CoA hydratase/isomerase domains and multiple enzyme activities including 1,4-dihydroxy-2-naphthoyl-CoA synthase, enoyl-CoA hydratase, 3-hydroxybutyryl-CoA epimerase, and delta3-delta2 enoyl-CoA isomerase. The gene is associated with phylloquinone and menaquinone biosynthesis, fatty acid beta-oxidation, embryogenesis, virus-induced PTGS, and response to cold. It localizes to mitochondria and microtubules. CaDHNS is associated with germination rate, chlorophyll content, and drought tolerance. Studies of related genes in other species link the family to photochemical quenching.
