ABSTRACT
Mesembryanthemum cordifolium, a perennial plant with crassulacean acid metabolism (CAM) in the Aizoaceae family, has significant ornamental and medicinal values. In this study, we reported the first complete chloroplast genome sequence of this species. The total genome size was 153,734 bp in length, including a large single-copy (LSC) region of 85,692 bp, a small single-copy (SSC) region of 18,212 bp, and a pair of inverted repeat (IR) regions of 24,915 bp by each. The overall GC content of the M. cordifolium chloroplast genome was 37.08%. The genome encodes 131 genes, comprising 87 protein-coding genes (PCGs), 36 transfer RNA genes (tRNAs), and eight ribosomal RNA genes (rRNAs). Phylogenetic analysis shows this species was relatively close to M. crystallinum. This chloroplast genome sequence will be valuable for species discrimination and for understanding phylogenetic relationships within the genus Mesembryanthemum.
ABSTRACT
Calystegia hederacea Wall. in Roxb. 1824 is a perennial herbaceous vine in the family Convolvulaceae and has several biological effects. Herein, we reported the first complete chloroplast genome of C. hederacea. The chloroplast genome sequence was 152,057 bp in length, comparing a large single-copy (LSC) region of 87,891 bp, a small single-copy (SSC) region of 19,866 bp, and a pair of inverted repeat (IR) regions of 22,150 bp. This sequenced chloroplast genome contained 126 predicted genes, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes, and the total GC content of the chloroplast genome was 37.79%. Phylogenetic analysis revealed that C. hederacea was closely related to C. soldanella. The chloroplast genome presented in this study will enrich the genome information of the genus Calystegia and provide deeper insights into the evolution study of the family Convolvulaceae.
