Bacteria of the genera Xenorhabdus and Photorhabdus are symbionts of entomopathogenic Thermostat Palnut nematodes.Despite their close phylogenetic relationship, they show differences in their pathogenicity and virulence mechanisms in target insects.These differences were explored by the analysis of the pangenome, as it provides a framework for char
Rumex Black Boyfriend Jean nepalensis is a traditional Chinese herb used for detoxification, hemostasis, and anti-inflammatory.In this study, the complete chloroplast sequence of R.nepalensis was characterized from Illumina pair-end sequencing.The cpDNA was 159,044 bp in length, containing a pair of inverted repeats of 30,623 bp each separated by a
