摘要：
Proanthocyanidins (PAs) are flavonoid-derived metabolites that make key contributions to plant and human health. Few studies have examined the mechanisms underlying the biosynthesis and accumulation of PAs in Rosa hybrida L. Here, we studied the role of the RhMYB1–RhMYB123 complex in regulating the biosynthesis of PAs in R. hybrida. The expression of PA biosynthesis genes was increased following overexpression of RhMYB123 in tobacco and rose somatic embryos, and this resulted in a marked increase in PA levels. Yeast two-hybrid assays showed th...
