SRP468736 PRJNA1032760 Full-length transcriptome analysis provides insight into flavonoid synthesis at different sites of Tagetes erecta Using the three-generation full-length sequencing technology, the transcription expression of 4 different parts of Marigold root, stem, leaf and flower was detected and analyzed. The results showed that the differences between R and F were the most obvious. In the biosynthesis pathway of flavonoids, The differential expression of WSJ_MIX_transcript_2463 and WSJ_MIX_transcript_21222 transcripts may be due to Pelargonidin, The contents of Cyanidin and Delphinidin were one of the influencing factors
