多様なマンゴー品種におけるフラボノイドを介した色彩変化の分子メカニズムを解明するマルチオミクス解析

Mango, as a major tropical fruit, is deeply loved by consumers due to its unique color and flavor. Fruit color is one of the important quality traits that determine its nutritional and commercial value. There are significant differences in the peel color of mango germplasm resources. However, the reason for the color difference in fruits is still unclear. In this study, we selected 43 representative mango varieties from the National Mango Germplasm Resources Nursery. Through the evaluation of germplasm resources fruit peels of 43 mango varieties, combined with transcriptomics and metabolomics, it was found that flavonoids play a decisive role in the color changes of mango peel. Overexpression of MiMYB33 can alter the color of tomato fruits by promoting an increase in flavonoid content. This study provides important theoretical basis for the subsequent research on mango fruit color and the cultivation of mango varieties that meet market demand.
