Characterization of the complete chloroplast genome of Actinidia melliana (Actinidiaceae)

TL;DR

This paper reports the complete chloroplast genome of Actinidia melliana, providing new genetic data for evolutionary and conservation studies.

Contribution

The first complete chloroplast genome sequence of Actinidia melliana is presented, offering new insights into Actinidiaceae evolution.

Findings

The chloroplast genome is 156,159 bp long with specific LSC, SSC, and IR regions.

133 genes were annotated, including protein-coding, tRNA, and rRNA genes.

Phylogenetic analysis shows A. melliana is closely related to A. cylindrica var. cylindrica.

Abstract

Actinidia melliana is a unique Actinidia species whose genomic data is extremely lacking. In this study, we reported the complete chloroplast genome of A. melliana for the first time, which has a total length of 156,159 bp, consisting of a large single-copy (LSC) region of 90,525 bp, a small single-copy (SSC) region of 20,578 bp, and a pair of inverted repeat (IR) regions with 22,528 bp each. A total of 133 genes were annotated, including 84 protein-coding genes, 41 transfer RNA genes (tRNA) and 8 ribosomal RNA genes (rRNA). Phylogenetic analysis alongside 28 other species in the Actinidiaceae family revealed that A. melliana is most closely related to A. cylindrica var. cylindrica. This study provides new genetic resources for evolutionary studies of Actinidia and supports future efforts in species identification and conservation within the genus.
