Abstract

The invention discloses a gene for improving the plant disease resistance and application thereof. The gene LeAct1 codes an agmatine transferase, which has a DNA (Deoxyribonucleic Acid) sequence shown as SEQ ID NO.1 in a sequence table, or has a DNA sequence capable of being hybridized with SEQ ID NO.1 under the strictly strict condition, or the gene LeAct1 codes a DNA sequence with the same amino acid sequence as the SEQ ID NO.1 in the sequence table. The gene is transformed and imported into a receiver plant genome; the agmatine transferase is expressed; and the disease resistance capability of a receiver plant can be improved. When the gene is applied to the agricultural biological technology breeding for improving the crop disease-resistant properties, the breeding period can be greatly shortened; and the breeding efficiency is improved.

Description

technical field

[0001] The invention belongs to the field of genetic engineering, in particular to a gene for improving plant disease resistance and its application. Background technique

[0002] Tomato yellow leaf curl disease (TYLCD) is a devastating disease that is extremely difficult to control in tomato production. The disease was first discovered in the Jordan River area of ​​Israel, and then broke out in large areas around the world. The harm is becoming more and more serious in China (Antignus&Cohen, 1994; Boulton, 2003; Guoyanmei et al., 2009). The disease is caused by geminiviruses, especially Tomato yellow leaf curl virus (TYLCV) is the most harmful in China (Li Jiawei et al., 2016). There is a lack of TYLCV resistance genes in tomato cultivation germplasm resources, and the resistance genes Ty-1-Ty-5 identified so far are all derived from wild relatives. Among them, Ty-2 has a significantly stronger inhibitory effect on virus replication than Ty-1 / Ty-3, and the...
