Annotation:
Analysis of exomes from 434 bread wheat accessions (the WHEALBI collection) identified almost 25 thousand putative introgressed segments of at least 2 Mb. The most frequent donor of the introgressions was Triticum timopheevii or its close relatives. Besides, we identified multiple events where distal chromosomal segments of one subgenome were duplicated in the genome and replaced the homoeologous segment in another subgenome, possibly by the process of inter-homoeologue recombination. The study produced an extensive catalogue of the wheat introgression landscape, providing a useful resource for wheat breeding.
