A1 — Solanum lycopersicum

Summary

SOLYC12G088880.2, also known as PAR, A1, or SlFLDH, encodes a protein with farnesol dehydrogenase, cinnamoyl-CoA reductase, dihydroflavanol 4-reductase, and flavanone 4-reductase activities, belonging to the epimerase/dehydratase and NAD(P)-binding domain superfamilies. In tomato, this gene is associated with anthocyanin, cytokinin, fatty acid, and chlorophyll breakdown, as well as farnesol and brassinosteroid metabolism, flavonoid metabolism, and responses to water, flooding, and phenylpropanoid stimuli. It has been linked to fruit type, color, shape, and size, flower and leaf color, carotene and carotenoid content, sugar content, anthocyanin content, stomatal resistance, and oxidative stress response. The encoded protein localizes to the ER, vacuole, plasmalemma, cytoplasm, and nucleus. Studies of related genes in other species connect the family to abscisic acid sensitivity and climacteric fruit ripening.
