Abstract

The invention discloses a method for efficiently and rapidly inhibiting endogenous-gene expression of cynodon dactylon. As genetic transformation of cynodon dactylon is quite difficult, the development of gene-function research and molecular breeding work of cynodon dactylon is seriously restricted. According to the new method, expression of endogenous genes of cynodon dactylon is specifically reduced through agrobacterium tumefaciens mediated transformation rice-tungro-bacilliform-virus-gene silencing vectors, and efficient and rapid technical means are provided for researching the gene function of cynodon dactylon. The method includes the following steps of 1, cloning of cynodon-dactylon target gene segments; 2, construction of the virus-induced gene silencing vectors; 3, cynodon-dactylon plant agrobacterium infection; 4, gene-expression-abundance molecular detection. By means of the method, expression of the endogenous genes of the cynodon dactylon can be successfully reduced by 50% or above.

Description

technical field [0001] The invention relates to a method for efficiently and rapidly inhibiting endogenous gene expression of bermudagrass by virus-induced gene silencing technology mediated by Agrobacterium, and belongs to the fields of genetic engineering and biotechnology. Background technique [0002] Bermudagrass (Cynodondactylon (L.) Pers.) is a plant of the genus Bermudagrass in the Poaceae Sansevieriae subfamily. It is an important warm-season turfgrass, forage and soil and water conservation plant. It is resistant to drought, salt, trampling, It has many advantages such as few pests and diseases, fast growth, thick grass layer, etc. It is widely used in the construction of slope protection lawns and grazing grasslands such as warm temperate, subtropical and tropical lawns, parks and road green belts, rivers and hillsides. very important position. [0003] In-depth research on the functions of important genes related to stress resistance and development of bermudagr...
