A kind of peony myb protein and its coding gene and application

Abstract

The invention belongs to the field of plant gene breeding, and in particular relates to a peony MYB protein, its encoding gene and its application. The amino acid sequence of the peony MYB protein is shown in SEQ ID No.1, the nucleotide sequence of the gene encoding the protein is shown in SEQ ID No.2, and the gene can regulate the synthesis of anthocyanins in tobacco leaves , to make tobacco leaves mottled, which is obviously different from the effects of other anthocyanin-regulated genes that have been reported, and can make tobacco bloom in advance. Thus, this gene has a dual role in the simultaneous regulation of anthocyanins and flowering time, which has not been found in other species. The peony MYB protein and its encoding gene provided by the invention can not only provide important gene resources for peony breeding, but also can be applied to the breeding of other flower plants.

Description

technical field [0001] The invention belongs to the field of plant gene breeding, and in particular relates to a peony MYB protein, its encoding gene and its application. Background technique [0002] Colored plants are one of the key traits that people pay attention to in the breeding process, especially in the field of ornamental plant breeding, a new colored variety can produce huge economic benefits. For a long time, color plant breeding has been dominated by traditional hybrid breeding, which has disadvantages such as long breeding cycle and difficulty in obtaining specific traits. With the development of molecular biology technology, researchers have begun to pay attention to the use of genetic engineering methods to carry out flower breeding research. Its typical feature is that the breeding cycle is greatly shortened, and the use of functional genes can effectively obtain the target traits. The main component of the color of most plants is anthocyanin, and the diffe...
