不同生长期棉花叶片中类黄酮代谢物的变化与分布
Changes and distribution of flavonoid metabolites in cotton leaves at different growth stages
摘要
Abstract
[Objective]This study aims to investigate the dynamic changes of flavonoids in cotton leaves at different growth and development periods.[Methods]Cotton leaves of sGK156 at seedling stage,flourishing flowering stage,and boll opening stage were used as study materials,and the differential metabolites were analysed and flavonoids abundance was detected by ultra-high-performance liquid chromatography-tandem mass spectrometry.[Results]Differential compounds of cotton leaves at three different periods were mainly enriched in the biosynthesis of flavone and flavonol,and the biosynthesis of flavonoids.Compared with those at the flourishing flowering stage and boll opening stage,kaempferol-3-O-arabinopyranoside and naringenin in cotton leaves were significantly higher at the seedling stage,and the contents of 16 flavonoids such as astragalin,tiliroside,and quercetin in cotton leaves at flourishing flowering stage were significantly higher than those at seedling stage and boll opening stage,and the contents of 5 compounds of epicatechin,kaempferol-3-O-rutinoside,kaempferol-3-O-vicianoside,procyanidin B2,and fraxin were significantly higher at the boll opening stage compared with seedling stage and flourishing flowering stage.[Conclusion]This study further analyses the dynamic changes of flavonoid secondary metabolites in cotton leaves during different growth periods,and discover the dominantly expressed flavonoid metabolites in cotton leaves during different growth periods.It provides a theoretical basis for the further study and utilization of flavonoid metabolites in cotton leaves and the selection and breeding of excellent cotton varieties.关键词
