The first complete chloroplast genome sequence and phylogenetic analysis of Actinidia trichogyna

Actinidia trichogyna is primarily distributed in the high-altitude regions of southwest China and its genomic data resources are still lacking. In this study, we assembled and annotated its complete chloroplast genome, which spanned 156,507 bp and consisted of a large single-copy region of 88,295 bp, a small single-copy region of 20,610 bp and two inverted repeat regions of 23,801 bp. The genome contained 131 genes, including 84 protein-coding genes, 8 ribosomal RNA genes, and 39 transfer RNA genes. Phylogenetic analysis revealed that it formed an independent branch to other species in the Sect. Maculatae, suggesting its unique evolutionary history. This study provides valuable data resources for kiwifruit evolutionary and functional genomic studies.
