The complete chloroplast genome and phylogenetic analysis of Miq 1861 (Roseaceae).

The wild raspberry species Miq 1861 is a promising resource for breeding thermotolerant cultivars. Its complete chloroplast genome spans 155,935 base pairs (bp), featuring the classic quadripartite structure: an 18,729 bp small single-copy region, an 85,662 bp large single-copy region, and two 25,772 bp inverted repeats. A total of 130 genes were identified, including 86 protein-coding, 36 tRNA genes, and 8 rRNA genes. A maximum likelihood phylogenetic tree based on chloroplast genomes shows that , within the subgenus , is sister to the subgenus . This confirms the polyphyletic nature of the subgenus . The chloroplast genome assembly of enhances our understanding of its evolutionary history.
