Overexpression of four MiTFL1 genes from mango delays the flowering time in transgenic Arabidopsis

Abstract Background TERMINAL FLOWER 1 ( TFL1 ) belongs to the phosphatidylethanolamine-binding protein (PEBP) family, which is involved in inflorescence meristem development and represses flowering several plant species. In present study, four genes were cloned from mango Mangifera indica L.) variety ‘SiJiMi’ named MiTFL1-1 , MiTFL1-2 MiTFL1-3 MiTFL1-4 . Results Sequence analysis showed that encoded MiTFL1 proteins contained a conserved PEBP domain belonged group. Expression expressed not only vegetative organs but also reproductive expression levels related floral development. Overexpression of delayed transgenic Arabidopsis Additionally, changed flower morphology some plants. Yeast two-hybrid (Y2H) stress-related interacted with proteins. Conclusions The exhibited similar pattern, overexpression resulted flowering. affected organ Furthermore, could interact bHLH 14 - 3-3 These results indicate may play an important role process mango.
