Introduction of Bulked Segregant Analysis

Bulked Segregant Analysis (BSA) is a method for QTL mapping of extreme traits of animals and plants by using sample pooling. According to the extreme performance of the traits in the F2 generation, they were divided into two groups, and the DNA extracted from these two groups were hybridized with the cDNA with the test gene or its latory sequences to screen the molecular markers related to the tested trait. Then use the markers to analyze the separation between the markers and the traits in the analysis population to determine whether they are linked and the genetic distance between them, and for gene mapping. The BSA method only needs to extract DNA from two samples, while other QTL methods must extract DNA from each plant separately. Therefore, the BSA method is fast and convenient, and can quickly locate the molecular marker region closely linked to the target gene, and further excavate important functional genes.

Using bioinformatics methods to analyze the data obtained from Bulked Segregant Analysis sequencing, it is possible to locate the fertility genes, resistance genes, physiological genes, and morphological genes of plants. In addition, it can also conduct related research on variety resource management.

Application of Bulked Segregant Analysis

Locating crop fertility genes in the process of crop breeding.

Locating resistance-related genes in the process of crop resistance research.

Locating genes related to crop physiology and morphological traits.

Using in the research of species classification in species resource management.

Advantages of Bulked Segregant Analysis

Compared with other QTL analysis methods, the BSA analysis method has the following advantages:

The number of DNA samples to be extracted is small.

The difference between alleles can be determined.

It is widely used in various researches on crops.

Convenient and fast, it is a time-saving and more practical analysis technique.
