Striking variation in chromosome structure within Musa acuminata and its diploid cultivars
<p>The majority of cultivated bananas originated from inter- and intra(sub)specific crosses between two wild diploid species, <em>Musa acuminata</em> and <em>Musa balbisiana</em>. Hybridization and polyploidization events during the evolution of bananas led to the formation of clonally propagated cultivars characterized by a high level of genome heterozygosity and reduced fertility. The combination of low fertility of edible clones and differences in the chromosome structure among <em>M. acuminata</em> subspecies greatly hampers the breeding of improved banana cultivars. Using comparative oligo painting we investigated large chromosomal rearrangements in a set of wild <em>M. acuminata</em> subspecies and cultivars that originated by natural crosses. Additionally, we analyzed chromosome structure of F1 progeny that resulted from crosses between Mchare bananas and wild <em>M. acuminata </em>'Calcutta 4' genotype. Analysis of chromosome structure within <em>M. acuminata</em> revealed the presence of a large number of chromosomal rearrangements showing a correlation with banana speciation. Chromosome painting of F1 hybrids was complemented by Illumina resequencing, which enabled to identify the contribution of parental subgenomes to the diploid hybrid clones. Balanced presence of both parental genomes was revealed in all F1 hybrids with the exception of one clone, which contained only Mchare specific SNPs, and thus most probably originated from an unreduced diploid gamete of Mchare.</p>

Data from: The banana (Musa acuminata) genome and the evolution of monocotyledonous plants
Bananas (Musa spp.), including dessert and cooking types, are giant perennial monocotyledonous herbs of the order Zingiberales, a sister group to the well-studied Poales, which include cereals. Bananas are vital for food security in many tropical and subtropical countries and the most popular fruit in industrialized countries1. The Musa domestication process started some 7,000 years ago in Southeast Asia. It involved hybridizations between diverse species and subspecies, fostered by human migrations2, and selection of diploid and triploid seedless, parthenocarpic hybrids thereafter widely dispersed by vegetative propagation. Half of the current production relies on somaclones derived from a single triploid genotype (Cavendish)1. Pests and diseases have gradually become adapted, representing an imminent danger for global banana production3, 4. Here we describe the draft sequence of the 523-megabase genome of a Musa acuminata doubled-haploid genotype, providing a crucial stepping-stone for genetic improvement of banana. We detected three rounds of whole-genome duplications in the Musa lineage, independently of those previously described in the Poales lineage and the one we detected in the Arecales lineage. This first monocotyledon high-continuity whole-genome sequence reported outside Poales represents an essential bridge for comparative genome analysis in plants. As such, it clarifies commelinid-monocotyledon phylogenetic relationships, reveals Poaceae-specific features and has led to the discovery of conserved non-coding sequences predating monocotyledon–eudicotyledon divergence.
