Mitochondrial DNA B Resour. 2022 Jul 29;7(7):1389-1391. doi: 10.1080/23802359.2022.2102442. eCollection 2022.

Abstract

Acer miaotaiense P. C. Tsoong is a rare and endangered tree endemic to the Qinling Mountains of China and is listed as a national third-class protected plant. In this study, we sequenced the complete mitochondrial genome of Acer miaotaiense using the Illumina Novaseq 6000 and Nanopore platforms. The total mitochondrial genome length is 819,227 bp and has 69 genes, including 41 protein-coding, 25 tRNA, and 3 rRNA genes. The genome nucleotide composition was asymmetric, with an overall G + C content of 45.7%. Phylogenetic analysis indicated that Acer miaotaiense is closely related to the congeneric Acer yangbiense.

Keywords: Acer miaotaiense; mitochondrial genome; phylogenetic relationship.
