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

Carya ovatais a slow-growing, long-lived deciduous species that belongs to sectionCaryaof genusCarya. In this study, wede novoassembled the complete chloroplast genome ofC.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 thatC.ovatawas closely related toC. illinoinensis, a representative of sectionApocaryawithin the genusCarya.
