Abstract

Taxodium 'Zhongshanshan 401' is an important economic plant with ornamental and ecological values, and has been widely planted in southeastern China. In this study, the complete chloroplast (cp) genome of T. 'Zhongshanshan 401' was sequenced and illustrated to add the more genetic information. The entire cp genome of T. 'Zhongshanshan 401' was 132,037 bp in length with 35.3% overall GC content. The cp genome contained 120 genes, including 83 protein-coding genes, 33 tRNA genes, and four rRNA genes. Fifteen genes contain two exons and two contains three exons. Phylogenetic analysis based on whole cp genome sequences showed that T. 'Zhongshanshan 401' was more closely related to T. mucronatum.

Keywords: Taxodium ‘Zhongshanshan 401’; complete chloroplast genome; phylogenetic analysis.
