Abstract:
In this study, the complete chloroplast genome of Polemonium chinense was determined by next-generation sequencing technology. The plastome is 155,578 bp in length, with a large single-copy region (LSC) of 85,864 bp and a small single-copy region (SSC) of 18,246 bp, separated by a pair of inverted repeat regions (IRs) of 25,734 bp. It contains 135 genes, including 89 protein-coding genes, 37 tRNA genes, 8 rRNA genes, and 1 pseudogene. The overall GC content is 37.1%, while the corresponding values in the LSC, SSC and IR region are 35.1, 30.3, and 42.9%, respectively. The phylogenetic tree shows that Polemoniaceae is sister to Fouquieriaceae.

Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
