Open AccessConserved chromatin and repetitive patterns reveal slow genome evolution in frogs
Frogs are an ecologically diverse and phylogenetically ancient group of anuran amphibians that include important vertebrate cell and developmental model systems, notably the genus Xenopus. Here we report a high-q...

Open AccessGenome analyses reveal population structure and a purple stigma color gene candidate in finger millet
Finger millet is a key food security crop widely grown in eastern Africa, India and Nepal. Long considered a ‘poor man’s crop’, finger millet has regained attention over the past decade for its climate resilie...

Open AccessGenome and transcriptome mechanisms driving cephalopod evolution
Cephalopods are known for their large nervous systems, complex behaviors and morphological innovations. To investigate the genomic underpinnings of these features, we assembled the chromosomes of the Boston ma...

Article
Open AccessFour chromosome scale genomes and a pan-genome annotation to accelerate pecan tree breeding
Genome-enabled biotechnologies have the potential to accelerate breeding efforts in long-lived perennial crop species. Despite the transformative potential of molecular tools in pecan and other outcrossing tre...

Open AccessThe tepary bean genome provides insight into evolution and domestication under heat stress
Tepary bean (Phaseolus acutifolis A. Gray), native to the Sonoran Desert, is highly adapted to heat and drought. It is a sister species of common bean (Phaseolus vulgaris L.), the most important legume protein so...

Open AccessGenomic mechanisms of climate adaptation in polyploid bioenergy switchgrass
Long-term climate change and periodic environmental extremes threaten food and fuel security1 and global crop productivity2–4. Although molecular and adaptive breeding strategies can buffer the effects of climati...

Article
Open AccessThe barley pan-genome reveals the hidden legacy of mutation breeding
Genetic diversity is key to crop improvement. Owing to pervasive genomic structural variation, a single reference genome assembly cannot capture the full complement of sequence diversity of a crop species (kno...

Open AccessGenome biology of the paleotetraploid perennial biomass crop Miscanthus
Miscanthus is a perennial wild grass that is of global importance for paper production, roofing, horticultural plantings, and an emerging highly productive temperate biomass crop. We report a chromosome-scale ass...

Article
Open AccessThe genomic landscape of molecular responses to natural drought stress in Panicum hallii
Environmental stress is a major driver of ecological community dynamics and agricultural productivity. This is especially true for soil water availability, because drought is the greatest abiotic inhibitor of ...

Article
Open AccessA mosaic monoploid reference sequence for the highly complex genome of sugarcane
Sugarcane (Saccharum spp.) is a major crop for sugar and bioenergy production. Its highly polyploid, aneuploid, heterozygous, and interspecific genome poses major challenges for producing a reference sequence. We...

Article
Open AccessThe Kalanchoë genome provides insights into convergent evolution and building blocks of crassulacean acid metabolism
Crassulacean acid metabolism (CAM) is a water-use efficient adaptation of photosynthesis that has evolved independently many times in diverse lineages of flowering plants. We hypothesize that convergent evolut...

Open AccessSub genome anchored physical frameworks of the allotetraploid Upland cotton (Gossypium hirsutum L.) genome, and an approach toward reference-grade assemblies of polyploids
Like those of many agricultural crops, the cultivated cotton is an allotetraploid and has a large genome (~2.5 gigabase pairs). The two sub genomes, A and D, are highly similar but unequally sized and repeat-r...

Article
Open AccessGenome evolution in the allotetraploid frog Xenopus laevis
To explore the origins and consequences of tetraploidy in the African clawed frog, we sequenced the Xenopus laevis genome and compared it to the related diploid X. tropicalis genome. We characterize the allotetra...

Open AccessThe genome of the seagrass Zostera marina reveals angiosperm adaptation to the sea
Whole-genome sequencing of the seagrass Zostera, representing the first marine angiosperm genome to be fully sequenced, provides insight into the evolutionary changes associated with a transition to a marine envi...

Article
Open AccessThe genome of Eucalyptus grandis
Eucalypts are the world’s most widely planted hardwood trees. Their outstanding diversity, adaptability and growth have made them a global renewable resource of fibre and energy. We sequenced and assembled >94...

Article
Open AccessInsights into bilaterian evolution from three spiralian genomes
Comparative analysis of the genomes of one mollusc (Lottia gigantea) and two annelids (Capitella teleta and Helobdella robusta) enable a more complete reconstruction of genomic features of the last common ancesto...

Article
Open AccessAlgal genomes reveal evolutionary mosaicism and the fate of nucleomorphs
Cryptophyte and chlorarachniophyte algae are transitional forms in the widespread secondary endosymbiotic acquisition of photosynthesis by engulfment of eukaryotic algae. Unlike most secondary plastid-bearing ...

Article
Open AccessRepeated polyploidization of Gossypium genomes and the evolution of spinnable cotton fibres
The Gossypium genus is used to investigate emergent consequences of polyploidy in cotton species; comparative genomic analyses reveal a complex evolutionary history including interactions among subgenomes that re...

Article
Open AccessThe genomic basis of adaptive evolution in threespine sticklebacks
Marine stickleback fish have colonized and adapted to thousands of streams and lakes formed since the last ice age, providing an exceptional opportunity to characterize genomic mechanisms underlying repeated e...

Erratum: Genome sequence of the palaeopolyploid soybean
Nature 463, 178–183 (2010) During resubmission of this work, a paper was published1 that used a comparative genomics approach between soybean and maize to show that a single-base mutation in chromosome 19 acco...
