Variation in repeated nucleotide sequences sheds light on the phylogeny of the wheat B and G genomes.

Abstract

A general method based on variation in repeated nucleotide sequences was developed for the identification of diploid species most closely related to a specific genome of a polyploid species. The utility of this method was demonstrated by showing that Triticum speltoides is the most closely related extant species to both the B and G genomes of tetraploid wheats.
