Complete chloroplast genome features and phylogenetic implications of Cardamine fallax (O. E. Schulz) Nakai

Abstract

Cardamine fallax (O. E. Schulz) Nakai. is a perennial plant distributed in Eastern Asia. However, no extensive genomic studies are available on C. fallax. In this paper, the authors describe the complete chloroplast (cp) genome of C. fallax and its phylogenetic analysis. The cp genome is 154,797 bp in length with 36.3% GC content and consists of a pair of inverted repeats (IRs) of 26,521 bp that separated a large single-copy (LSC) region of 83,817 bp and a small single-copy (SSC) region of 17,938 bp. It was found to contain 113 unique genes, of which 80 were protein-coding genes, 29 were transfer RNAs, and four were ribosomal RNAs. Also, six PCGs, eight tRNA and four rRNA genes were duplicated in the IR region and one gene as a pseudogene. Phylogenetic analysis showed that all Cardamine species are highly conserved, and C. fallax was associated with the sister clade C. amaraeformis and C. parviflora.
