Abstract:

Abstract: This paper introduced flower pigments composition, and related enzymes and genes involved in the main pigments biosynthetic pathway in yellow flowers, and reviewed the advances in study on the biochemical and molecular biological mechanism of yellow flowers' formation are summarized, and analyzed the feasibility of using genetic engineering to breed yellow flower plants. The main pathways include inhibiting the gene expression of the key enzymes of anthocyanin biosynthesis or introducing some exotic related genes about yellow flower generation. This review intended to offer the reference on yellow flower molecular breeding. Finally, main problems and perspectives about the research of yellow flower genetic engineering were discussed.
