Problems solved by technology

[0005]Although GST has been confirmed to be involved in the transport and accumulation of anthocyanins in a variety of plants, most of the studies have focused on model plants or crops. For ornamental flowers in this The research on gene family is relatively scarce, especially in peony.

Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention are clearly and completely described below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] The technical solution provided by the present invention specifically isolates and identifies a GST gene involved in anthocyanin transport and accumulation from peony (P. suffruticosa), named PsGSTF3. Although the GSTs genes that have been confirmed to have the function of anthocyanin transport and accumulation play similar functions in different plants, their CDS sequences are not the same. Therefore, the isolation and identification of GSTs involved in the transport and accumulation of anthocyanins in tree peonies can enrich ...

Abstract

The invention discloses a GST gene participating in anthocyanin transport and accumulation in Paeonia suffruticosa (P.suffrutacosa) and application thereof. The GST gene participating in anthocyanin transport and accumulation is separated and identified from P.suffrutacosa, and the GST gene plays an important role in anthocyanin transport and accumulation, can enrich a transgenic material library of red characters of P.suffrutacosa flowers, and powerful support is provided for molecular breeding for cultivating and regulating red P.suffrutacosa flowers in the future.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a GST (Glutathione S-transferase) gene involved in anthocyanin transport and accumulation in peony and its application. Background technique [0002] Plant flower color is one of the important ornamental traits of ornamental plants, and improvement of flower color has always been an important breeding goal of horticulturalists. Peony (Paeonia suffruticosa) is a fine product of traditional famous flowers in my country. It is known as the "king of flowers". After long-term cultivation and selection, it has formed a variety of colors and is very popular in domestic and foreign markets. [0003] However, for a long time, the breeding mode of peony has been mainly based on hybridization between varieties, and the randomness and blindness in the breeding process are relatively high. It usually takes a lot of time and energy to obtain the ideal variety through multiple generations of select...
