摘要： The star fruit is a perennial woody fruit tree, which can blossom and bear fruit many times a year. The time and quantity of flowering are the key indicators of its economic value. However, the flowering molecular mechanism of star fruit is still unknown. This study provides a genome-wide analysis of the key flowering genes of star fruit. Based on a previous morphological study of flower bud differentiation, the reproductive buds, vegetative buds and mature leaves of star fruit were sampled for transcriptome analysis. The results showed that the expression of GI, COL4, COL5, FT, FCA, FVE, PIF4, LFY, SVP-like, AP1 and FUL was correlated with floral induction and transition. The expression of TFL1, SVP-like genes (Yangtao2015203 and Yangtao2021074) was correlated with the inhibition of floral transition. Thus, we proposed a putative network of flower blooming in star fruit. This study provides useful information for investigating the genetic mechanism of flowering in star fruit and other perennial woody fruit trees.
