Watermelon female lines gene C1WIP1 and chromosome translocation and linkage marker

Abstract

The invention belongs to the molecular biology field, and more specifically relates to watermelon female lines gene(i) C1WIP1( / i) and chromosome translocation and linkage marker, which comprises a DNA sequence of watermelon female lines gene(i) gy( / i) gene(i) C1WIP1( / i), its acquisition method, a molecular marker linked with the DNA sequence, a chromosome translocation section due to appearance of the watermelon female lines and its acquisition method. According to the invention, a classic gene positioning method and a whole genome re-sequencing technology are organically combined, and watermelon female lines gene(i) C1WIP1( / i) is rapidly and accurately cloned; a PCR technology is used for confirming that a watermelon spontaneous mutant material XHBFGM is appeared by female lines phenotype due to chromosome translocation, and a preliminary research is carried out on the effect mechanism of (i) C1WIP1( / i); By aiming at the existence of the chromosome translocation, the molecular marker linked with watermelon female lines gene(i) C1WIP1( / i) is designed, the watermelon female lines phenotype which takes XHBFGB as a transfer material can be rapidly detected, the molecular marker is used for assistant breeding, seed production cost of watermelon is greatly reduced, and the seed purity is increased.

Description

technical field [0001] The invention belongs to the field of molecular biology, and specifically relates to watermelon female line gene ClWIP1 and chromosome translocation and linkage markers, including: the DNA sequence of watermelon female line gene gy gene ClWIP1 and its obtaining method, the molecular marker linked thereto and its obtaining method, And the chromosomal translocation segment leading to the female line of watermelon and its obtaining method. Background technique [0002] Watermelon (Citrullus lanatus) is an annual herbaceous plant belonging to Cucurbitaceae Cucumber, and is an important economic crop widely cultivated at home and abroad. my country has a history of growing watermelons since the Han Dynasty. It is one of the earliest countries in the world to cultivate watermelons, and it is also the country with the largest watermelon cultivation area and the highest yield in the world. [0003] Watermelon is a model crop for the study of plant sex differe...

Problems solved by technology

[0006] In the current scientific research work, the design of markers based on the SNP / InDel differential sites obtained by whole genome resequencing has not yet been implemented to fine-map the watermelon gy gene, and the candidate gene of the gy gene has been found in the mapped gene region, and the candidate gene has not yet been identified. Verify in other groups, and finally get the watermelon gy gene
