Abstract

Sequencing of chloroplast genomes provides new data for phylogenetic studies of controversial species of the tribe Triticinae. One such species is Aegilops aucheri Boiss., which is considered to be a subspecies of Ae. speltoides Tausch. The chloroplast genomes of accessions k-2278 and k-657 of Ae. aucheri from different geographical origins were sequenced and annotated to complete the picture of the phylogenetic position of this representative of the genus Aegilops. The size of the plastomes of both samples was 135 668 bp. A phylogenetic tree based on the complete nucleotide sequence data of the chloroplast genomes of seven different Ae. aucheri accessions (five of which were already sequenced in the previous study) showed a separate position of this representative of the genus Aegilops from Ae. speltoides. The species status of Ae. aucheri is discussed in the context of these results.
