Abstract

The invention discloses R2R3 MYB transcription factors promoting anthocyanin formation in two orchids. The transcription factors are shown in Figure 1 and Figure 2, and the transcription factors are isolated and identified from Cattleya. A transgenic material library of orchid ploants with a red flower trait can be enriched through corresponding transcription factors, and strong support for molecular breeding of orchids with the red flower trait in the future is provided.

Description

technical field

[0001] The invention relates to the field of biotechnology, in particular to an R2R3 MYB transcription factor that promotes the formation of anthocyanins in orchids. Background technique

[0002] Due to the special flower shape and rich flower color of orchids, many of their natural species and cultivars 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 of species. 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 improve orchid flower color according to the preference of the market.

[0003] At present, the main method of orchid breeding is through interspecific hybridization. In the breeding process, the randomness and blindness are high, and it usually takes a lo...
