Differentially abundant anthocyanin compounds between Kunlun10 and purple Nierumuzha at three stages. A Numbers of differentially abundant anthocyanin compounds between varieties at each stage. B Heatmap showing the patterns of differential abundance across the 41 anthocyanin compounds at each stage. Cell colors correspond to the log10 magnitude of the difference in abundance (fold change values + 1): redder cells indicate higher abundance, and bluer cells indicate lower abundance. C Numbers of differentially accumulated anthocyanins shared and unique between the two varieties at the three developmental stages. D Content of four anthocyanin compounds absent from all stages of Kunlun10 and the early milk stage of Nierumuzha
