Abstract

The invention relates to rapid identification of MLO (Mycoplasma Like Organism) powdery mildew resistant genes of a melon, relates to comparative genomics of plants, genetics, bioinformatics and other disciplinary knowledge, and belongs to the field of biotechnology science of plants. The rapid identification is mainly carried by the following steps: 1) downloading the whole genome sequence of the melon, and acquiring MLO genes; 2) identifying the MLO genes; 3) obtaining the phylogenetic relationship of MLO genes; 4) comparing MLO powdery mildew resistant genes. By virtue of adopting the rapid identification, the powdery mildew resistant genes mining cycle of the melon can be effectively reduced, which is beneficial to the rapid identification of powdery mildew resistant genes; the identified candidate powdery mildew resistant genes are utilized to develop corresponding coseparation functional markers (such as SNR and SCAR) and can also be quickly used for assistant selection of molecular markers resistant to powdery mildew resistant genes, and the accuracy is high; in combination with other anti-disease gene molecular markers, a plurality of resistive breeding materials can be created, the breeding periods can be reduced, and the breeding efficiency can be increased; the foundation is provided for describing a powdery mildew resistant molecular mechanisms of the melon.

Description

technical field

[0001] The present invention is to quickly identify the powdery mildew gene of melon by means of sequencing the whole genome sequence of melon, using methods such as plant comparative genomics, genetics, bioinformatics and candidate gene strategies, and mainly involves the download of the whole genome sequence of melon and the identification of candidate genes , gene comparison, clustering and other means, and then identify the powdery mildew gene, which belongs to the field of plant biotechnology science. Background technique

[0002] Melon is also called sweet melon or muskmelon. Melon is named for its sweet taste, and it is also called muskmelon because of its delicate fragrance. Melon is a summer melon to cool off the summer heat, and its nutritional value is comparable to that of watermelon. According to the measurement, except that the content of water and protein in melon is lower than that of watermelon, other nutrients are not less than that of wat...
