Complete chloroplast genomes of five <i>Aegilops aucheri</i> Boiss. accessions having different geographical origins

The subject of this study is <i>Aegilops aucheri</i> Boiss. 1844: a member of the section <i>Sitopsis</i>, subsection <i>Truncata</i>. This species is infrequently included in phylogenetic studies and is commonly regarded as a heterotypic synonym of <i>Aegilops speltoides</i> Tausch. The aim of this study was to detect genetic differences between <i>Ae. aucheri</i> and <i>Ae. speltoides</i> using the phylogenetic signal retrieved from chloroplast genomes. Plastomes of five <i>Ae. aucheri</i> accessions from different geographical locations were sequenced, annotated, and subjected to a phylogenetic analysis. Plastome sizes were found to range between 135,666 and 135,668 bp in <i>Ae. aucheri</i>. Comparative analysis of the chloroplast genome sequences from five <i>Ae. aucheri</i> accessions revealed single-nucleotide polymorphisms (SNPs) and insertions/deletions (indels) relative to the <i>Ae. speltoides</i> plastome. To gain a more comprehensive understanding of the genetic divergence within the <i>Truncata</i> subsection, sequencing the nuclear genome of <i>Ae. aucheri</i> and comparing it to that of <i>Ae. speltoides</i> is essential.
