show Abstracthide AbstractTo explore the relationship between light intensity and flavonoids accumulation in safflower flowers, transcriptome analysis was performed in this study. The safflower flowers under different light intensities were sequenced. A total of 82.01 GB data was gotten. The Q30 of each sample base was greater than or equal to 88.41%. 129 544 Unigenes were generated with 170 757 704 bp, 1 318 bp, 2 090 bp, and 41.59% in total length, mean length, N50 and GC content, respectively.
