Huang W.Z., and Li Z.G., 2025, Genetic regulation of nocturnal flowering in pitaya floral morphology, olfactory cues, and pollination adaptation, International Journal of Horticulture, 15(4): 162-170 (doi: 10.5376/ijh.2025.15.0017)

This study investigated the genetic regulation mechanism of night flowering in Pitaya (Hylocereus spp.). In the application of multi-omics technology, transcriptome and metabolome analysis were used to reveal the central role of sugar and hormone signaling in flower bud induction, as well as the potential role of epigenetic and miRNA in flowering regulation. The flower structure and aroma components showed a high degree of coordination with nocturnal pollinators, providing a new perspective for understanding the pollination adaptation of pitaya fruit. The integration of genetic and environmental factors plays a very important role in optimizing the flowering time and breeding strategy of Pitaya fruit, improving the yield and quality of Pitaya fruit, and providing theoretical basis for future research.
