Bananas (Musa spp.), including dessert and cooking types, are giant perennial monocotyledonous herbs of the order Zingiberales, a sister group to well-studied Poales, which include cereals. vital for food security in many tropical subtropical countries most popular fruit industrialized countries. The Musa domestication process started some 7,000 years ago Southeast Asia. It involved hybridizations between diverse species subspecies, fostered by human migrations, selection diploid triploid...
Abstract Crop landraces have unique local agroecological and societal functions offer important genetic resources for plant breeding. Recognition of the value landrace diversity concern about its erosion on farms led to sustained efforts establish ex situ collections worldwide. The degree which these succeeded in conserving has not been comprehensively assessed. Here we modelled potential distributions eco-geographically distinguishable groups 25 cereal, pulse starchy root/tuber/fruit crops...
Bananas and plantains (Musa spp.) are grown in more than a hundred tropical subtropical countries provide staple food for hundreds of millions people. They seed-sterile crops propagated clonally this makes them vulnerable to rapid spread devastating diseases at the same time hampers breeding improved cultivars. Although socio-economic importance bananas cannot be overestimated, they remain outside focus major research programs. This slows down study nuclear genome development molecular tools...
The production of triploid banana and plantain (Musa spp.) cultivars with improved characteristics (e.g. greater disease resistance or higher yield), while still preserving the main features current popular taste cooking quality), remains a major challenge for Musa breeders. In this regard, breeders require sound knowledge lineage sterile cultivars, to select diploid parents that are able transmit desirable traits, together breeding strategy ensuring final triploidization sterility. Highly...
Identifying the molecular mechanisms underlying tolerance to abiotic stresses is important in crop breeding. A comprehensive understanding of gene families associated with drought therefore highly relevant. NAC transcription factors form a large plant-specific family involved regulation tissue development and responses biotic stresses. The main goal this study was set up framework orthologous groups determined by an expert sequence comparison genes from both monocots dicots. In order clarify...
Banana (Musa sp.) is a vegetatively propagated, low fertility, potentially hybrid and polyploid crop. These qualities make the breeding targeted genetic improvement of this crop difficult long process. The Genome-Wide Association Study (GWAS) approach becoming widely used in plants has proven efficient to detecting candidate genes for traits interest, especially cereals. GWAS not been applied yet propagated However, successful banana would considerably help unravel genomic basis interest...
Abstract Crop wild relatives are valuable resources for future genetic improvement. Here, we report the de novo genome assembly of Musa itinerans , a disease-resistant banana relative in subtropical China. The assembled size was 462.1 Mb, covering 75.2% (615.2Mb) and containing 32, 456 predicted protein-coding genes. Since approximate divergence around 5.8 million years ago, genomes acuminata have shown conserved collinearity. Gene family expansions contractions enrichment analysis revealed...
Hybridization and introgressions are important evolutionary forces in plants. They contribute to the domestication of many species, including understudied clonal crops. Here, we examine their role a crop outmost importance, banana (Musa ssp.). We used genome-wide SNPs generated for 154 diploid cultivars 68 samples wild M. acuminata estimate geo-localize contribution different subspecies cultivated banana. further investigated domesticate transition New Guinea, an center. found high levels...
Abstract Background Ensete glaucum (2n = 2x 18) is a giant herbaceous monocotyledonous plant in the small Musaceae family along with banana (Musa). A high-quality reference genome sequence assembly of E. resource for functional and evolutionary studies Ensete, Musaceae, Zingiberales. Findings Using Oxford Nanopore Technologies, chromosome conformation capture (Hi-C), Illumina RNA survey sequence, supported by molecular cytogenetics, we report 481.5 Mb 9 pseudo-chromosomes 36,836 genes. total...
Bananas and plantains (Musa spp.) are one of the major fruit crops worldwide with acknowledged importance as a staple food for millions people. The rich genetic diversity this crop is, however, endangered by diseases, adverse environmental conditions changed farming practices, need its characterization preservation is urgent. With aim providing simple robust approach molecular Musa species, we developed an optimized genotyping platform using 19 published sequence repeat markers.The system...

Background and Aims Dessert cooking bananas are vegetatively propagated crops of great importance for both the subsistence livelihood people in developing countries. A wide diversity diploid triploid cultivars including AA, AB, AS, AT, AAA, AAB, ABB, AAS AAT genomic constitutions exists. Within each this genome groups, classified into subgroups that reported to correspond varieties clonally derived from other after a single sexual event. The number those founding events at basis is matter...
Abstract The CGIAR genebank International Musa Germplasm Transit Centre (ITC) currently holds 1617 banana accessions from 38 countries as an in vitro collection, backed-up by a cryopreserved collection to safeguard global diversity perpetuity. ITC also serves vital safety backup and transit centre for national genebanks ensures that germplasm is clean of pests diseases freely available under the Treaty on Plant Genetic Resources Food Agriculture. In more than 35 years activity, has...
Bananas (Musa spp.) are a major staple food for hundreds of millions people in developing countries. The cultivated varieties seedless and parthenocarpic clones which the ancestral origin remains to be clarified. most important cultivars triploids with an AAA, AAB or ABB genome constitution, A B genomes provided by M. acuminata balbisiana, respectively. Previous studies suggested that inter-genome recombinations were relatively common banana more likely have passed through intermediate...
Abstract To explore the transcriptomic global response to osmotic stress in roots, 18 mRNA-seq libraries were generated from three triploid banana genotypes grown under mild (5% PEG) and control conditions. Illumina sequencing produced 568 million high quality reads, of which 70–84% mapped diploid reference genome. Using different uni- multivariate statistics, 92 genes commonly identified as differentially expressed genotypes. our house workflow analyze GO enriched underlying biochemical...

Bananas (Musa spp.) are an important crop worldwide. Most modern cultivars resulted from a complex polyploidization history that comprised three whole genome duplications (WGDs) shaping the haploid Musa genome, followed by inter- and intra-specific crosses between acuminata M. balbisiana (A B respectively). Unresolved hybridizations finally led to banana diversification into several autotriploid (AAA) allotriploid (AAB ABB). Using transcriptomic data, we investigated impact of structure on...
Bananas (Musa spp.), including dessert and cooking types, are of major importance in the tropics. Due to extremely high levels sterility, diversity cultivated bananas is fixed over long periods time existing genotypes. This pattern puts banana-based agrosystems at risk. Therefore, assessing extent wild banana diversity, conserving it making available for further use a priority. We report here collection new germplasm Autonomous Region Bougainville, Papua New Guinea. In total, 61 accessions...
Societal Impact Statement Climate resilient crops will become increasingly important, especially in regions where smallholder farmers are vulnerable to climate extremes. Enset, a multipurpose perennial staple crop consumed by over 20 million people Ethiopia, purportedly provides food security during periods of drought. Here, we find evidence that frequent severe drought events led an increase enset production area. This is consistent with broader pattern whereby preferentially cultivate and...
