The Complete Chloroplast Genome and Characteristics Analysis of Musa basjoo Siebold

Abstract Musa basjoo Siebold is an ornamental plant often seen in gardens and farmhouses. It can also be used as a kind of Chinese herbal medicine. The decoct soup of its pseudo stem can help relieve the heat. Its pseudo stem and leaves are diuretic. The decoct soup of its dried flower can treat cerebral hemorrhage. Its root can be decocted together with ginger and licorice to cure gonorrhea and diabetes. The chloroplast genome study on Musa basjoo Siebold is rarely seen. This paper showed that the length of the chloroplast genome Musa basjoo Siebold was 172,322 bp, with 36.45% GC content. Musa basjoo Siebold included a large single-copy region of 90,160 bp, a small single-copy region of 11,668 bp, and a pair of inverted repeats of 35,247 bp. Comparing the genomic structure and sequence data of closely related species, we revealed the conserved gene order of the IR and LSC/SSC regions, which provided a very inspiring discovery for future phylogenetic research. Overall, this study is the first time an evolutionary tree of the genus Musa species has been constructed with the complete chloroplast genome sequence. We can see that there is no obvious multi-branching in the genus, and Musa basjoo Siebold, and Musa itinerans are the closest relatives.
