Abstract
In order to study the pathways of biosynthesis of flavonoids in Sophora japonica, 113 797 unigenes were obtained by Trinity software, with an average length of 803 bp, of which 72 752 unigenes were obtained from the database by high-throughput sequencing, and a total of 38 891 SSR loci were searched. Through the metabolic pathway analysis, we found that there were 135 unigenes involved in the biosynthesis of flavonoids and 959 unigene involved in other secondary metabolic pathways. Further analysis of genes involved in rutin biosynthesis revealed that 24 were associated with CHS, 52 were associated with FLS, and 11 were associated with UFGT. The obtained data of S. japonica transcriptome lays the foundation for studying the pathways of biosynthesis of flavonoids in S. japonica and provides theoretical basis for the formation of the quality of S. japonica.
