Identification of Closely Related Polymorphisms with Striga Resistance Using Next Generation Sequencing
摘要
Molecular markers are powerful tools to enhance speed of breeding. Recent advances of sequencing technology allow us to identify most polymorphisms in a genome. Whole genome resequencing of an F2 segregating population can identify those polymorphisms that co-segregate with a mutant phenotype, which theoretically include the gene responsible for Striga resistance gained through mutagenesis. This protocol explains the isolation of high-quality genomic DNA for sequencing and step-by-step procedures for single nucleotide polymorphism (SNP) identification from bulked F2 sequences.
