This study was carried out to investigate the possibility of isolating the useful gene of soybean plant, anthocyanin, through NGS (Next Generation Sequencing) and molecular biology experiments. Lespedeza cuneata. G. don is a resource plant but has many useful materials. Especially, D-pinitol, which has anti-diabetic function, is contained in a large amount. However, the gene related to the biosynthesis of D-piniol has not been isolated in the non-spermatid. Lespedeza cuneata. G. don was treated with abiotic stress (drought), total RNA was extracted, and a library was constructed to perform NGS. In this way, the genes involved in D-pinitol biosynthesis were isolated and sequenced in silico. In order to support this, ononitol epimerase involved in D-pinitol amplification was identified using the Blast program and RT-PCR confirmed the increased gene expression in vitro, and the gene was isolated and identified by convergence study.
