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...
Coffee, tea, and chocolate converge Caffeine has evolved multiple times among plant species, but no one knows whether these events involved similar genes. Denoeud et al. sequenced the Coffea canephora (coffee) genome identified a conserved gene order (see Perspective by Zamir). Although this species underwent fewer duplications than related relevant caffeine genes experienced tandem that expanded their numbers within species. Scientists have seen independent expansions in distantly of tea...
Abstract Sugarcane ( Saccharum spp.) is a major crop for sugar and bioenergy production. Its highly polyploid, aneuploid, heterozygous, interspecific genome poses challenges producing reference sequence. We exploited colinearity with sorghum to produce BAC-based monoploid sequence of sugarcane. A minimum tiling path 4660 sugarcane BAC that best covers the gene-rich part was selected based on whole-genome profiling, sequenced, assembled in 382-Mb single high-quality total 25,316...
Banana cultivars (Musa ssp.) are diploid, triploid and tetraploid hybrids derived from Musa acuminata balbisiana. We presented a high-quality draft genome assembly of M. balbisiana with 430 Mb (87%) assembled into 11 chromosomes. identified that the recent divergence (A-genome) (B-genome) occurred after lineage-specific whole-genome duplication, B-genome may be more sensitive to fractionation process compared A-genome. Homoeologous exchanges frequently between A- B-subgenomes in...
Sugarcane, the world's most harvested crop by tonnage, has shaped global history, trade and geopolitics, is currently responsible for 80% of sugar production worldwide
Whole genome duplications (WGDs) occurred in the distant evolutionary history of many lineages and are particularly frequent flowering plant lineages. Following paleopolyploidization plants, most duplicated genes deleted by intrachromosomal recombination, a process referred to as fractionation. In examples studied so far, disproportionately lost from one parental subgenomes (biased fractionation) subgenome having lowest number is more expressed (genome dominance). present study, we analyzed...
Banana is one of the world's favorite fruits and most important crops for developing countries. The banana reference genome sequence (Musa acuminata) was recently released. Given taxonomic position Musa, completed genomic has particular comparative value to provide fresh insights about evolution monocotyledons. study been enhanced by a number tools resources that allows harnessing its sequence. First, we set up essential such as Community Annotation System, phylogenomics metabolic pathways....
Summary Modern sugarcane ( Saccharum spp.) is an important grass that contributes 60% of the raw sugar produced worldwide and has a high biofuel production potential. It was created about century ago through hybridization two highly polyploid species, namely S. officinarum spontaneum. We investigated genome dynamics in this context by analyzing homoeologous sequences (97 126 kb) region already been studied several cereals. Our findings indicate species diverged 1.5–2 million years from one...
Musa species (Zingiberaceae, Zingiberales) including bananas and plantains are collectively the fourth most important crop in developing countries. Knowledge concerning genome structure origin of distinct cultivars has greatly increased over last few years. Until now, however, no large-scale analyses genomic sequence have been conducted. This study compares two with orthologous regions rice genome. We produced 1.4 Mb from 13 BAC clones, annotated analyzed them along 4 previously sequenced...
Abstract The genome of modern sugarcane cultivars is highly polyploid (∼12x), aneuploid, interspecific origin, and contains 10 Gb DNA. Its size complexity represent a major challenge for the isolation agronomically important genes. Here we report on first attempt to isolate gene from by map-based cloning, targeting durable rust resistance (Bru1). We describe genomic strategies that have developed overcome constraints associated with high polyploidy in successive steps cloning approaches,...
A consensus genetic map of tetraploid cotton was constructed using six high-density maps and after the integration a sequence-based marker redundancy check. Public SSR libraries (17,343 markers) were curated for sequence 90% as similarity cutoff. As result, 20% markers (3,410) could be considered redundant with some other markers. The information had been crucial part process, in which most informative interspecific Gossypium hirsutum×G. barbadense used assembling high density (HDC) cotton....
Using GWAS approaches, we detected independent resistant markers in sugarcane towards a vectored virus disease. Based on comparative genomics, several candidate genes potentially involved virus/aphid/plant interactions were pinpointed. Yellow leaf of is an emerging viral disease whose causal agent Polerovirus, the Sugarcane yellow (SCYLV) transmitted by aphids. To identify quantitative trait loci controlling resistance to which are direct relevance for breeding, undertook genome-wide...
Abstract Among legumes (Fabaceae) capable of nitrogen-fixing nodulation, several Aeschynomene spp. use a unique symbiotic process that is independent Nod factors and infection threads. They are also distinctive in developing root stem nodules with photosynthetic bradyrhizobia. Despite the significance these features, their understanding remains limited. To overcome such limitations, we conduct genetic studies nodulation evenia , supported by development genome sequence for A. transcriptomic...
• Modern sugarcane (Saccharum spp.) is the leading sugar crop and a primary energy crop. It has highest level of 'vertical' redundancy (2n = 12x 120) all polyploid plants studied to date. was produced about century ago through hybridization between two autopolyploid species, namely S. officinarum spontaneum. In order investigate genome dynamics in this highly context, we sequenced compared seven hom(oe)ologous haplotypes (bacterial artificial chromosome clones). Our analysis revealed high...

Modern sugarcane cultivars (Saccharum spp.) are high polyploids, aneuploids (2n = ~12x ~120) derived from interspecific hybridizations between the domesticated sweet species Saccharum officinarum and wild S. spontaneum.To analyse architecture origin of such a complex genome, we analysed sequences all 12 hom(oe)ologous haplotypes (BAC clones) two distinct genomic regions typical modern cultivar, as well corresponding sequence in Miscanthus sinense Sorghum bicolor, monitored their distribution...
The advent of next-generation sequencing (NGS) has revolutionized the study single nucleotide polymorphisms (SNPs), making it increasingly cost-effective. Haplotypes, which combine alleles from adjacent variants, offer several advantages over bi-allelic SNPs, including enhanced information content, reduced dimensionality, and improved statistical power in genomic studies. These benefits are particularly significant for polyploid species, where distinguishing all homologous copies using SNP...
Cultivated peanut, Arachis hypogaea is an allotetraploid of recent origin, with AABB genome. In common many other polyploids, it seems that a severe genetic bottle-neck was imposed at the species via hybridisation two wild and spontaneous chromosome duplication. Therefore, study genome peanut hampered both by crop's low diversity its polyploidy. contrast to cultivated most are diploid high diversity. The genomes therefore attractive, simplify construction physical maps, for isolation...
