Mitochondrial genome of African rice (<i>Oryza glaberrima</i>): comparative analysis and phylogenetic relationships.

ABSTRACT: We report the first complete mitochondrial genome of African rice (Oryza glaberrima), spanning 376,795 bp across two circular chromosomes (GC: 43.9%) and encoding 65 genes (39 protein-coding, 21 tRNA, 5 rRNA). Repeat analysis identified 37 simple sequence repeats and 50 dispersed repeats (including a 7,116 bp palindromic repeat), comprising 18.37% of the genome. Phylogenetic analysis confirmed O. glaberrima's placement within Oryza. This reference mitogenome enhances understanding of mitochondrial genome diversity and evolution, providing a foundation for genetic studies and molecular breeding strategies for African rice improvement.
