Lycium ruthenicum is a characteristic plant resource in Northwest China. The fruit with high anthocyanin content is the main reason for its high nutritional value and economic value, while the regulation of key genes regulating anthocyanin biosynthesis in black fruit is not clear. In this study, high-throughput sequencing technology was used to compare the expression differences of all genes in black and purple fruits. The purple samples obtained 45.13 and 51.49 M Raw reads, while...
