Problems solved by technology

The most important thing is that lignin is involved in the formation of wood and the improvement of its strength. However, the existence of lignin also has many negative effects on practical applications. For example, the degradation of lignin has always been one of the difficulties in the bamboo pulp and paper industry.

Abstract

The invention belongs to the technical field of plant genetic engineering, and particularly discloses a Phyllostachys edulis MYB transcription factor gene PeMYB103A, the nucleotide sequence of which is as shown in SEQ ID NO: 1. The invention further discloses application of the Phyllostachys edulis MYB transcription factor gene PeMYB103A in increasing the content of cellulose, the content of hemicellulose and the content of biomass and reducing the content of lignin. The Phyllostachys edulis MYB transcription factor gene PeMYB103A provided by the invention has a wide application prospect in directional breeding of plants, and a new gene resource is provided for plant genetic engineering.

Description

technical field [0001] The invention belongs to the technical field of plant genetic engineering, and in particular relates to a MYB transcription factor gene PeMYB103A of moso bamboo and its application. Background technique [0002] The application of Phyllostachys edulis involves various aspects such as furniture, construction and papermaking, and has broad application prospects and huge market value. [0003] Transcription factors, also known as trans-acting factors, refer to DNA-binding proteins that can specifically interact with cis-acting elements in the gene promoter region, and activate or inhibit certain genes through the interaction between them and other related proteins. transcription of some genes. During the long-term evolution of plants, a complex and multi-level secondary cell wall biosynthesis regulatory network has been formed. Various transcription factors are involved in the secondary cell wall biosynthesis regulatory network, which can be regulated by...
