Comparative genome and metabolome analyses uncover the evolution and flavonoid biosynthesis between Apocynum venetum and Apocynum hendersonii.

ABSTRACT: Apocynum species have great application prospects in textile and phytoremediation of saline soil, are rich in flavonoids, and possess medicinal significance. Here, we report the draft genomes of Apocynum venetum and Apocynum hendersonii, and elucidate their evolutionary relationship. The high synteny and collinearity between the two suggested that they have experienced the same WGD event. Comparative analysis revealed that flavone 3-hydroxylase (ApF3H) and differentially evolved flavonoid 3-O-glucosyl transferase (ApUFGT) genes are critical for determining natural variation in flavonoid biosynthesis between the species. Overexpression of ApF3H-1 enhanced the total flavonoid content and promoted the antioxidant capacity of transformed plants
