What this paper is about
Complete chloroplast genomes for two members of the milkweed subfamily, Gomphocarpus siniacus and Duvalia velutina, sequenced and compared against other Apocynaceae.
Both carry 119 genes. Gomphocarpus is the genus that includes balloon plant, which is naturalized in the United States.
Summarised here from the abstract below. Not the authors’ words.
Abstract
We studied the complete chloroplast genome of Gomphocarpus siniacus and Duvalia velutina from Asclepiadoideae subfamily; due to their medicinal importance and distribution worldwide their interest became high. In this study we analyzed the complete chloroplast genomes of G. siniacus and D. velutina using Illumina sequencing technology. The sequences were compared with the other species from Apocynaceae family. The complete genome of G. siniacus is 162,570 bp while D. velutina has154, 478 bp in length. Both genomes consist of 119 genes; encode 31 tRNA genes, and eight rRNA genes. Comparative studies of the two genomes showed variations in SSR markers in which G. siniacus possesses 223 while D. velutina has 186. This could be used for barcoding in order to aid in easy identification of the species. Phylogenetic analysis on the other hand reaffirms the tribal position of G. siniacus in Asclepiadeae and D. velutina in Ceropegieae. These findings could be used in subsequent research studies of angiosperms identification, genetic engineering, herb genomics and phylogenomic studies of Apocynaceae family.
