The ripening process of Chinese bayberries () is intricate, involving a multitude of molecular interactions. Here, we integrated transcriptomic and metabolomic analysis across three developmental stages of the () to elucidate these processes. A differential gene expression analysis categorized the genes into four distinct groups based on their expression patterns. Gene ontology and pathway analyses highlighted processes such as cellular and metabolic processes, including protein and sucrose metabolism. A metabolomic analysis revealed significant variations in metabolite profiles, underscoring the dynamic interplay between genes and metabolites during ripening. Flavonoid biosynthesis and starch and sucrose metabolism were identified as key pathways, with specific genes and metabolites playing crucial roles. Our findings provide insights into the molecular mechanisms governing fruit ripening in and offer potential targets for breeding strategies aimed at enhancing fruit quality.
杨梅的成熟过程（）错综复杂，涉及多种分子相互作用。在这里，我们整合了三个发育阶段的转录组和代谢组分析（），以阐明这些过程。差异基因表达分析根据基因的表达模式将基因分为四个不同的组。基因本体论和途径分析强调了细胞和代谢过程等过程，包括蛋白质和蔗糖代谢。代谢组学分析揭示了代谢物谱的显著变化，强调了成熟过程中基因和代谢物之间的动态相互作用。类黄酮生物合成和淀粉和蔗糖代谢被确定为关键途径，特定的基因和代谢物起着关键作用。我们的研究结果为控制杨梅果实成熟的分子机制提供了深入了解，并为旨在提高果实品质的育种策略提供了潜在的目标。
