ssp.(synonym), a putative ancestor of the genus, has been classified within, although recent phylogenetic studies suggest that it represents a distinct species. This study reports the first complete chloroplast genome of, highlighting its structure, genetic composition, and phylogenetic relationships withinand related Triticiceae species. Phylogeny reconstruction based on the maximum-likelihood method reveals notable genetic similarity betweenand, supporting their genetic and phylogenetic distinction. Here, we assembled the complete, annotated chloroplast genome sequence ofssp.. The genome is 137,068 base pair (bp) long. It is the first complete chloroplast genome that can be used as a reference genome for further analysis. The genome can be accessed on GenBank with the accession number OQ700974. This work sheds light on the evolutionary history ofand contributes to our understanding of chloroplast genomics in cereal ancestors, with potential applications in improving cereal crop resilience, advancing breeding strategies, and informing conservation efforts for genetic diversity.
