Analysis of YUC and TAA/TAR Gene Families in Tomato

Auxin is a vital phytohormone, but its synthesis pathway poorly understood. This study used bioinformatic analysis to identify and analyze the gene family members that encode tomato auxin biosynthesis. The FZY encoding flavin-containing monooxygenases were retrieved from genome database. DNAMAN revealed nine genes within landmark domain WL(I/V)VATGENAE, between FAD NADPH domains. Phylogenetic showed in closely related YUC Arabidopsis thaliana. A qRT-PCR SlFZY2, SlFZY3, SlFZY4-1, SlFZY5 highly expressed flower organs. of promoter cis-acting elements light-responsive promoters all tomato, indicating their sensitivity light signals. Furthermore, SlFZY4-2, SlFZY5, SlFZY7 contain low-temperature-responsive elements. demonstrated SlTAA5 expression was 2.22 times SlTAA3 roots, pistils 83.58 stamens during flowering stage. Therefore, various are involved regulating development floral organs responsive abiotic stresses, such as low temperature weak light.
