黑莓果实发育过程中黄酮和花色苷积累的作用机制研究
Study on the mechanism of flavonoids and anthocyanins accumulation during blackberry fruit development
[目的]重点研究第三代新兴的小浆果类果树黄酮和花色苷积累的动态变化,明确黑莓果实发育过程中黄酮和花色苷合成相关代谢物的变化规律,探究其果实成熟过程中颜色变化和花色苷积累的作用机制,以期为蔷薇科悬钩子属高效利用花色苷等药用成分提供参考依据。[方法]以黑莓'Chester'品种不同发育阶段的果实为植物材料,对果实发育过程中颜色和代谢物的变化进行观察和测定,同时分析相应时期关键基因和转录因子在转录层面的表达情况。[结果]研究结果表明,在黑莓果实发育过程…查看全部>>
[Objective]This study focused on the dynamic changes of flavonoid and anthocyanin accumulation in the third generation of small berry fruit trees,to clarify the changes of flavonoid and anthocyanin synthesis related metabolites during fruit development of blackberry,and to explore the mechanism of color change and anthocyanin accumulation during fruit ripening,to provide reference for the efficient utilization of anthocyanins and other medicinal components i…查看全部>>
