Description
Summary:	<i>Secale strictum</i> ssp. <i>africanum</i> (synonym <i>Secale africanum</i>), a putative ancestor of the genus <i>Secale</i>, has been classified within <i>Secale strictum</i>, although recent phylogenetic studies suggest that it represents a distinct species. This study reports the first complete chloroplast genome of <i>S. africanum</i>, highlighting its structure, genetic composition, and phylogenetic relationships within <i>Secale</i> and related Triticiceae species. Phylogeny reconstruction based on the maximum-likelihood method reveals notable genetic similarity between <i>S. strictum</i> and <i>S. africanum</i>, supporting their genetic and phylogenetic distinction. Here, we assembled the complete, annotated chloroplast genome sequence of <i>Secale strictum</i> ssp. <i>africanum</i>. 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 of <i>Secale</i> and 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.
