Comparative analyses of chloroplast genomes from 13 Lagerstroemia (Lythraceae) species: identification of highly divergent regions and inference of phylogenetic relationships

Complete chloroplast genome sequence of turnip (Brassica rapa. ssp. rapa): genome structure and phylogenetic analysis

“…The distribution of GC content in turnip cp genome was similar with that in Lagerstroemia (Zheng et al. 2020 ). Conversely, the overall AT content in SSC region (71.9%) was higher than that in the IR region (57.7%), and the content of A and T were 31.4 and 32.3%, respectively.…”

Comparative Analyses of Chloroplast Genomes From 14 Zanthoxylum Species: Identification of Variable DNA Markers and Phylogenetic Relationships Within the Genus

“…Z. bungeanum and Z. schinifolium recorded in the Chinese Pharmacopeia belong to a different subgenus and are relatively distantly related, consistent with the research of Wang et al (2016). Identification success rate (%) = [(the total number of species -the number of species with bootstrap values below 50%)/the total number of species] × 100% (Zheng et al, 2020). Overall, the phylogenetic position of Zanthoxylum revealed by our phylogenetic tree is more credible than in previous studies given the higher number of cp genomes analyzed in our research.…”

“…SSRs are important genetic markers to identify closely related species (Zhao et al, 2020;Zheng et al, 2020). Here, SSRs in the cp genomes of 14 Zanthoxylum species were detected using MISA software.…”

“…To evaluate the ability of the seven selected sequences to identify Zanthoxylum plants, we constructed the ML tree separately based on each sequence (Supplementary Figure 1). The number of species successfully identified in the ML tree is used to evaluate the resolution power of the sequence (Zheng et al, 2020). When the value of the node is lower than 50, the species on the branch cannot be distinguished (Zheng et al, 2020).…”

“…The number of species successfully identified in the ML tree is used to evaluate the resolution power of the sequence (Zheng et al, 2020). When the value of the node is lower than 50, the species on the branch cannot be distinguished (Zheng et al, 2020). matK and rpl32-trnL-UAG had the same highest resolution power (identification success rate) of 93%, followed by trnH-GUG-psbA with 86%, and ycf4-cemA with 79%.…”
