Problems solved by technology

However, compared to the huge taxa and rich color variations of Orchidaceae, as well as the diversity and specificity of homologous genes among species, only three R2R3 MYB transcription factors that can promote anthocyanin synthesis are important for future Orchidaceae flower color molecules. Breeding improvements are not enough

Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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.

[0014] The technical solution provided by the present invention is to isolate and identify two R2R3 MYB transcription factors that can promote the synthesis of anthocyanins in flowers from Cattleya Rhyncholaeliocattleya Beauty Girl 'KOVA' (KOVA), which are respectively Rhyncholaeliocattleya Promoted Anthocyanin Pigmentation 1 (RcPAP1) and Rhyncholaeliocattleya Promoted Anthocyanin Pigmentation 2 (RcPAP2).

[0015] Among them, some members of the R2R3 MYB fami...

Abstract

The invention discloses R2R3MYB transcription factors that promote anthocyanin formation in two kinds of orchids. The transcription factors are shown in SEQ ID NO: 1 and SEQ ID NO: 2, and the transcription factors are isolated and identified from Cattleya. The corresponding transcription factors can enrich the transgenic material library for the red trait of orchid flowers, which provides strong support for the molecular breeding of orchid red trait flowers in the future.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an R2R3 MYB transcription factor that promotes anthocyanin formation in orchids. Background technique [0002] Because orchids have special flower shapes and rich flower colors, many natural species and cultivated varieties thereof have high ornamental value and are widely popular in the world. Among them, Phalaenopsis spp., Oncidium spp. and Cattleya spp. are the most popular in the market, with the highest reputation and a wide variety. Flower color is one of the important ornamental characteristics of these orchids and a major contributor to their ornamental value. Therefore, it is one of the main goals of breeders to carry out breeding and improvement of orchid flower color according to the liking of the market public. [0003] At present, the main means of orchid breeding is selective breeding through interspecific hybridization. The randomness and blindness in the breeding p...
