Flower induction in pitaya (Hylocereus polyrhizus) is regulated by complex gene networks involving multiple signaling pathways that ensure flower bud (FB) formation, but its molecular determinants remain largely unknown. In this study, we aimed to identify key genes and involved analyzing transcriptomics profiles from differentiating buds. Our results indicate the process driven a combination of sugar, hormone, transcription factor (TF), flowering-related genes. We found during FB period, levels starch, auxin (AUX), cytokinin (CTK) active forms dihydrozeatin riboside (dhZR), zeatin (ZR), N6-isopentenyladenosine (iPA), brassinosteroid (BR) increase late stage (LS), while gibberellins (GA3, GA4) decrease, metabolic hormonal shift essential for flowering. Differential expression analysis identified starch sugar metabolism, AUX, CTK, BR synthesis, (GA) degradation, with notable differential photoperiod (COL, CDF, TCP), age-related (SPL), flowering (FT, FTIP, AGL, SOC1). This study reveals multidimensional regulatory network formation pitaya, primarily mediated crosstalk between hormone pathways, providing new insights into mechanism pitaya.
