Abstract

Triticummilitinae Zhuk. et Migusch., a tetraploid wheat with the GAA genome, is considered a natural naked mutant of Triticum timopheevii Zhuk. Previously, the karyotype and crossing characteristics of this wheat were examined. To clarify the origin and relationships of T. militinae with other representatives of the wheat family, analysis of its chloroplast genome, which remained unexplored, is of great interest. In the present study, for the first time, sequencing and annotation of the complete chloroplast genome of T. militinae, the size of which was found to be 135 898 bp, was conducted. The plastome of this wheat is composed of two inverted repeats, each of 21 552 bp in length, the small single-copy (SSC) region of 12 791 bp, and the large single-copy (LSC) region of 80 003 bp. The chloroplast genome of T. militinae contains 132 annotated structural genes, of which 85 genes are protein-coding, 31 are tRNA genes, and four genes code for rRNA.
