RESUMO
Pulsatilla chinensis f. alba D. K. Zang 1993 is a forma of Pulsatilla chinensis (Bge.) Regel, the root of P. chinensis is traditional Chinese medicine called Pulsatillae radix. The biggest difference between P. chinensis f. alba and P. chinensis is that P. chinensis f. alba sepals is white. The complete chloroplast genome of P. chinensis f. alba was sequenced using the Illumina NovaSeq platform for the first time. The lengths of the genome, large single-copy (LSC), small single-copy (SSC), two inverted repeats (IRs), and GC content were 163,654 bp, 82,355 bp, 19,069 bp, 31,115 bp, and 37.2%, respectively. It had 134 genes, including 90 protein-coding genes, 36 tRNA genes, and eight rRNA genes. The maximum-likelihood tree indicated that P. chinensis f. alba had a closer relationship with P. chinensis. This study would provide a theoretical basis for the further study of Pulsatilla plants genetics phylogenetic research.
RESUMO
Grewia biloba var. parviflora (Bunge) Hand.-Mazz. (1933), a shrub or small tree, is native to northern and southern China. It is an excellent relief and medicinal plant. The complete chloroplast genome is 158,043 bp in length, with a large single-copy region of 86,957 bp, a small single-copy region of 20,138 bp, two inverted repeat regions of 25,474 bp each, and a GC content of 37.4%. There were 129 genes annotated, including 84 known protein-coding genes, 37 tRNAs, and eight rRNAs. The phylogenetic trees are constructed using plastome data from 38 species and the maximum-likelihood method. The results of the chloroplast genome-wide analysis and the phylogenetic tree show the taxonomic phylogeny of the G. biloba var. parviflora in relation to other species, increasing the accuracy of the phylogenetic classification of the plant.
