Kiwifruit (Actinidia) has been recently domesticated as a horticultural crop with remarkably economic and nutritional value. In this study, by combining sequence datasets from Oxford Nanopore long-reads and Illumina short-reads, we de novo assembled two mitogenomes of Actinidia latifolia and A. valvata, respectively. The results indicated that the A. latifolia mitogenome has a single, circular, 825,163 bp molecule while the A. valvata mitogenome possesses two distinct circular molecules, 781,709 and 301,558 bp, respectively. We characterized the genome structure, repeated sequences, DNA transfers, and dN/dS selections. The phylogenetic analyses showed that A. valvata and A. arguta, or A. latifolia and A. eriantha, were clustered together, respectively. This study provides valuable sequence resources for evolutionary study and molecular breeding in kiwifruit.
