Abstract

A comprehensively analysis of the transcriptomics and metabolomics was conducted to investigate the mechanism of plant growth regulators on the quality of jujube fruit. After the application of plant growth regulators, a total of 3097 differentially expressed genes (DEGs) were identified, which were mainly annotated in 123 pathways such as flavonoid biosynthesis, metabolism of alanine, aspartate, and glutamate. In addition, 1091 differential expressed metabolites (DEMs), including 519 up-regulated and 572 down-regulated metabolites, were significantly altered after application of plant growth regulators. DEGs and DEMs simultaneously annotated 69 metabolic pathways, including biosynthesis of phenylpropane, flavonoid, starch and sucrose. The key genes in flavonoid biosynthesis pathway were revealed, which may play an important role in plant growth regulator regulation quality of jujube fruit. Besides, the application of plant growth regulator during the jujube flowering period increased the contents of gibberellin and indole-3-acetic acid in leaves, and decreased the contents of abscisic acid. The results may help to reveal the metabolic network and molecular mechanism of plant growth regulators in jujube fruit.

摘要

对转录组学和代谢组学进行了全面分析，以研究植物生长调节剂对枣果实品质的作用机制。在使用植物生长调节剂后，共鉴定出 3097 个差异表达基因（DEGs），这些基因主要注释在黄酮类生物合成、丙氨酸、天冬氨酸和谷氨酸代谢等 123 个途径中。此外，1091 个差异表达代谢物（DEMs），包括 519 个上调和 572 个下调代谢物，在使用植物生长调节剂后发生了显著变化。DEGs 和 DEMs 同时注释了 69 个代谢途径，包括苯丙烷、黄酮类、淀粉和蔗糖的生物合成。揭示了类黄酮生物合成途径中的关键基因，这些基因可能在植物生长调节剂调控枣果实品质中发挥重要作用。此外，在枣树花期使用植物生长调节剂增加了叶片中赤霉素和吲哚-3-乙酸的含量，降低了脱落酸的含量。这些结果可能有助于揭示植物生长调节剂在枣果实中的代谢网络和分子机制。
