Phylogenenetic relationships in the wheat-aegilops alliance through the prism of the chloroplast genome
The nucleotide sequence of the chloroplast genome of the diploid wheat Triticum sinskajae A. Filat. et Kurk. was determined. The comparison of the assembled genome with the chloroplast genomes of some di- and polyploid species of the wheat-aegilops alliance revealed a high evolutionary conservativeness and proximity to the plastid genome of T.monococcum, while the other diploid wheat T.urartu is somewhat distant from them. Alignment of the nucleotide sequences of complete chloroplast genomes of diploid wheat with those of diploid aegilops from the Sitopsis and Vertebrata sections, as well as with tetra - and hexaploid wheats from the turgidum-aestivum and timopheevii groups, allowed to establish that different aegilops from the subsection Truncata, close to the current Aegilops speltoides, were as maternal forms during their formation but not directly Ae.speltoides.
