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

Characterization of the complete plastome sequence of Korean endemic, Cardamine glechomifolia H.Lév. (Brassicaceae, Brassicales)

In this study, we report the complete plastome sequence of Cardamine glechomifolia H.Lév. 1913 (NCBI acc. no. OP894664). This plastome shows typical quadripartite structure. The plastome size is 154,307 bp, which consists of 84,015 bp large single-copy (LSC), 17,690 bp small single-copy (SSC), and 26,301 bp inverted repeat (IR) regions. The plastome contains 112 genes, including 78 protein-coding, 30 tRNA, and four rRNA genes. The infA gene is pseudogenized. Sixteen genes contain one intron and two genes (clpP and ycf3) have two introns. The phylogenomic analysis conducted in our study reveals that the genus Cardamine, which encompasses C. glechomifolia, exhibits three distinct clades. In order to elucidate the interrelationship among the three clades, it is imperative to conduct additional investigations by augmenting the number of Cardamine samples.

Complete chloroplast genome of Cardamine hupingshanensis K.M.Liu, L.B.Chen, H.F.Bai & L.H.Liu (Brassicaceae) in Enshi, Hubei

Cardamine hupingshanensis K.M.Liu, L.B.Chen, H.F.Bai & L.H.Liu 2008, also called Cardamine enshiensis, belongs to the genus Cardamine, Brassicaceae. As a plant with selenium enrichment ability, it has high development value. Here, we analyzed the chloroplast genome of C. hupingshanensis. The complete chloroplast genome had a total size of 154,832 bp with a typical quadripartite structure, including a large single-copy region (LSC, 83,908 bp) and a small single-copy region (SSC, 17,938 bp), separated by a pair of inverted repeat regions (IRs, 26,493 bp). Genome annotation showed the chloroplast genome contained 113 unique genes, including 79 protein-coding genes, 30 tRNA genes, and four rRNA genes. A total of 143 SSRs were found in the chloroplast genome. Phylogenetic analysis showed that C. hupingshanensis was closer to the C. circaeoides and C. lyrata. This chloroplast genome resource will be useful for study of the phylogeny and evolution of Cardamine in the future.
