Plastome and RAD-seq of Polygonatum odoratum
收藏资源简介：
Polygonatum odoratum (Mill.) Druce (Asparagaceae, Asparagales) is a widely cultivated medicinal herb in China. However, this useful herb is understudied despite being known as a medicinal resource with top grade medical and edible properties since long. In this study, P. odoratum and four cultivars were investigated. The variations in morphological characteristics and vegetative phases of each cultivars were observed. For genetic aspect, the plastid genome of P. odoratum varies in length from 154,569 bp to 155,491 bp, containing a large single-copy region of 83,486â84,459 bp, a small single-copy region of 18,292â18,471 bp, and two inverted repeats of 26,302â26,370 bp. A total of 131 genes were predicted, including 85 protein-coding, 38 tRNA, and eight rRNA genes. Genome comparisons revealed a slight variation in the sequence across the five accessions, but two highly variable regions (trnC-petN and rpl32-trnL) were detected when comparing the four different cultivars. For the RAD-seq ma...
