F — Asparagus officinalis

Summary

AoDFR (A4U43_C06F2420) on asparagus chromosome 6 encodes an NAD-dependent epimerase/dehydratase domain-containing protein with multiple annotated enzyme activities, including anthocyanidin reductase, racemase and epimerase, cinnamyl-alcohol dehydrogenase, dihydroflavonol 4-reductase, and flavanone 4-reductase activity, along with NADP binding and general oxidoreductase activity. The gene is associated with anthocyanin and flavonoid biosynthesis and has been linked to photosynthetic rate and anthocyanin content. Its product is predicted to localise to the nucleus. Studies of related genes in other species connect the family to traits including flower, fruit, leaf and petal colour, flavonoid and carotenoid content, photosynthetic parameters such as net photosynthetic rate and quantum yield, shoot biomass, drought tolerance, and water use efficiency.
