Targeted capture of homoeologous coding and noncoding sequence in polyploid cotton.

ABSTRACT: Targeted sequence capture is a promising technology in many areas in biology. These methods enable efficient and relatively inexpensive sequencing of hundreds to thousands of genes or genomic regions from many more individuals than is practical using whole-genome sequencing approaches. Here, we demonstrate the feasibility of target enrichment using sequence capture in polyploid cotton. To capture and sequence both members of each gene pair (homeologs) of wild and domesticated Gossypium hirsutum, we created custom hybridization probes to target 1000 genes (500 pairs of homeologs) using information from the cotton transcriptome. Two widely divergent samples of G. hirsutum were hybridized to four custom NimbleGen capture arrays containing probes for targeted genes. We show that the two coresi
