The complete chloroplast genome sequence of flowering banana, Musa ornata.

ABSTRACT: Musa ornata (flowering banana) is one of more than 50 species of banana in the genus Musa of the family Musaceae. As sources of resistance to pathogens exist in germplasm, M. ornata is one of the possible hybrid parents for ameliorate commercial banana varieties. Herein, we report the complete chloroplast genome of M. ornata. The total length of the chloroplast genome is 169,989 bp with 36.82% GC content. The genome consisted of 35,426 bp of a pair of inverted repeat regions (IRs), 10,775 bp of small single copy region (SSC) and 88,362 bp of large single-copy region (LSC). A total of 136 functional genes were annotated, including 113 unique genes comprising 79 protein-coding genes, 4 ribosomal RNA (rRNA) genes and 30 transfer RNA (tRNA) genes. Maximum-likelihood phylogenetic analysis with Musaceae and Zingiberaceae species revealed that M. ornata is most closely grouped with Musa acuminata.

Project description:Banana streak virus (BSV) belongs to the members of the genus Badnavirus, family Caulimoviridae. At present, BSV contains nine species in the International Committee on Taxonomy of Viruses (ICTV) classification report (2018b release). Previous study indicated that the viral particles of Banana streak virus Acuminata Yunnan (BSV-Acum) were purified from banana (Cavendish Musa AAA group) leaves in Yunnan Province, China, and its complete genome was obtained. To further determine whether this sample infecting with Banana streak GF virus (BSGFV), the polymerase chain reaction (PCR) cloning and complete genome analysis of the Banana streak GF virus Yunnan isolate (BSGFV-YN) isolate were carried out in this study. The result showed that BSGFV-YN infecting Cavendish Musa AAA group was co-infecting this sample. Its genome contains a total of 7,325 bp in length with 42% GC content. This complete genome sequence was deposited in GenBank under accession number MN296502. Sequence analysis showed that the complete genome of BSGFV-YN was 98.14% sequence similarity to BSGFV Goldfinger, while it was 49.10-57.09% to other BSV species. Two phylogenetic trees based on the complete genome and ORFIII polyprotein indicated that BSGFV-YN and other BSV species clustered into a group, while it was the highest homology with BSGFV Goldfinger. Although BSGFV-YN and BSGFV Goldfinger were highly homologous, their cultivating bananas are different. The former cultivating banana was from Cavendish Musa AAA group, while the latter cultivating banana was from Goldfinger Musa AAAB group. Compared with BSGFV Goldfinger, the genome of BSGFV-YN has an extra multiple repetitive sequences in the intergenetic region between ORFIII and ORFI, suggesting that this region might be related to host selection. In summary, a BSGFV-YN distant from BSV-Acum was identified from the same sample, and its complete genome sequence was determined and analyzed. The study extends the polymorphism of BSVs in China and provides scientific clue for the evolutionary relationship with host selection of badnaviruses.
