Characterization and phylogenetic relationships analysis of the complete chloroplast genome of Carya ovata

Abstract

Carya ovata is a slow-growing, long-lived deciduous species that belongs to section Carya of genus Carya. In this study, we de novo assembled the complete chloroplast genome of C. ovata, and analyzed its phylogenetic relationship. The circular genome was 160,765 bp in length, comprising a large single-copy region (89,975 bp), a small single-copy region (18,788 bp), and a pair of inverted repeat regions (26,001 bp each). The chloroplast genome was predicted to contain 131 genes, including 83 protein-coding genes, 40 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. Overall, the GC content of the chloroplast genome was 36.16%. Phylogenetic analysis suggested that C. ovata was closely related to C. illinoinensis, a representative of section Apocarya within the genus Carya.
