Gene PLD gamma capable of preventing anthracnose

Abstract

The invention relates to the technical field of biology, in particular to a gene PLD gamma capable of preventing anthracnose. The gene PLD gamma is encoded by a base sequence shown in a sequence tableSEQ ID NO:1; the invention further discloses a protein encoded by the gene PLD gamma, and the protein is composed of amino acid sequences shown in the sequence table SEQ ID NO:2; a phospholipase D inhibitor is applied to the gene PLD gamma or the protein encoded by gene PLD gamma for preventing banana anthracnose.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of biotechnology, in particular to a gene PLDγ for preventing and treating anthracnose. [0003] 【Background technique】 [0004] Banana is a monocotyledonous plant of Musa (Musaceae) and is an important economic crop growing in tropical and subtropical regions. In recent years, the annual output of bananas in the world is about 100 million tons, which has become the main economic pillar in many parts of the world. my country's banana production has always been in the forefront of the world and showing a growing trend. Banana is a typical climacteric fruit. It is difficult to store and transport for a long time, and the loss caused by harvesting and transport is quite serious. In recent years, the post-harvest loss rate of bananas in my country has been as high as nearly 50%, which is much higher than the average loss rate of 25% in my country and 5% in developed countries. [0005] Phospholipids are not only...

AI Technical Summary

Problems solved by technology

[0008] At present, there have been many reports on the prevention and treatment of banana fruit anthracnose. Chemical agents such as carbendazim, thiophanate-methyl, Spauke, prohyne, and teketol are mainly used for the prevention and control of banana anthracnose. Rational use can easily lead to excessive pesticide residues in bananas, seriously endangering human health, thereby affecting the import and export of bananas and causing huge losses

The incidence rate of anthracnose in banana fruit at different stages of growth and development is not yet clear, and the expression level of phospholipase D, especially PLDγ, and the mechanism of action of banana fruit under anthracnose stress are still unclear
