Auxin is a vital phytohormone. but its synthesis pathway is poorly understood. This study used bioinformatic analysis to identify and analyze the gene family members that encode tomato auxin biosynthesis. The FZY gene family members encoding flavin-containing monooxygenases were retrieved from the tomato genome database. https://www.parisnaturalfoodes.shop/product-category/all-purpose-baking-flour/
