RT Journal Article SR Electronic T1 Genome sequencing of Musa acuminata Dwarf Cavendish reveals a duplication of a large segment of chromosome 2 JF bioRxiv FD Cold Spring Harbor Laboratory SP 691923 DO 10.1101/691923 A1 Mareike Busche A1 Boas Pucker A1 Prisca Viehöver A1 Bernd Weisshaar A1 Ralf Stracke YR 2019 UL http://biorxiv.org/content/early/2019/10/21/691923.abstract AB Different Musa species, subspecies, and cultivars are currently investigated to reveal their genomic diversity. Here, we compare the genome sequence of one of the commercially most important cultivars, Musa acuminata Dwarf Cavendish, against the Pahang reference genome assembly. Numerous small sequence variants were detected and the ploidy of the cultivar presented here was determined as triploid based on sequence variant frequencies. Illumina sequence data also revealed a duplication of a large segment on the long arm of chromosome 2 in the Dwarf Cavendish genome. Comparison against previously sequenced cultivars provided evidence that this duplication is unique to Dwarf Cavendish. Although no functional relevance of this duplication was identified, this example shows the potential of plants to tolerate such aneuploidies.
