Ruben Rellán-Álvarez, Guillaume Lobet, Heike Lindner, Pierre-Luc Pradier, Jose Sebastian, Muh-Ching Yee, Yu Geng, Charlotte Trontin, Therese LaRue, Amanda Schrager-Lavelle, Cara H. Haney, Rita Nieu, Julin Maloof, John P. Vogel & José R. Dinneny
Root systems develop different root types that individually sense cues from their local environment and integrate this information with systemic signals. This complex multi-dimensional amalgam of inputs enables continuous adjustment of root growth rates, direction and metabolic activity that define a dynamic physical network. Current methods for analyzing root biology balance physiological relevance with imaging capability. To bridge this divide, we developed an integrated imaging system called Growth and Luminescence Observatory for Roots (GLO-Roots) that...

Danièle L. Filiault, Evangeline S. Ballerini, Terezie Mandakova, Gökçe Aköz, Nathan J. Derieg, Jeremy Schmutz, Jerry Jenkins, Jane Grimwood, Shengqiang Shu, Richard D. Hayes, Uffe Hellsten, Kerrie Barry, Juying Yan, Sirma Mihaltcheva, Miroslava Karafiatova, Viktoria Nizhynska, Elena M. Kramer, Martin A. Lysak, Scott A. Hodges & Magnus Nordborg
The columbine genus Aquilegia is a classic example of an adaptive radiation, involving a wide variety of pollinators and habitats. Here we present the genome assembly of A. coerulea 'Goldsmith', complemented by high-coverage sequencing data from 10 wild species covering the world-wide distribution. Our analyses reveal extensive allele sharing among species, and demonstrate that introgression and selection played a role in the Aquilegia radiation. We also present the remarkable discovery that the evolutionary history of...

Data from: Genome-wide association analysis of stalk biomass and anatomical traits in maize

Background: Maize stover is an important source of crop residues and a promising sustainable energy source in the United States. Stalk is the main component of stover, representing about half of stover dry weight. Characterization of genetic determinants of stalk traits provide a foundation to optimize maize stover as a biofuel feedstock. We investigated maize natural genetic variation in genome-wide association studies (GWAS) to detect candidate genes associated with traits related to stalk biomass (stalk...

Delayed transition from the vegetative stage to the reproductive stage of development and increased plant height have been shown to increase biomass productivity in grasses. The goal of this project was to detect quantitative trait loci using extremes from a large synthetic population, as well as a related recombinant inbred line mapping population for these two traits. Ten thousand individuals from a B73 × Mo17 noninbred population intermated for 14 generations (IBM Syn14) were grown...

Data from: Convergent losses of decay mechanisms and rapid turnover of symbiosis genes in mycorrhizal mutualists

Costa, Jeanne Dore, Dimitrios Floudas, Gilles Gay, Mariangela Girlanda, Bernard Henrissat, Sylvie Herrmann, Jaqueline Hess, Nils Hogberg, Tomas Johansson, Hassine-Radhouane Khouja, Kurt LaButti, Urs Lahrmann … & Francis Martin
To elucidate the genetic bases of mycorrhizal lifestyle evolution, we sequenced new fungal genomes, including 13 ectomycorrhizal (ECM), orchid (ORM) and ericoid (ERM) species, and five saprotrophs, which we analyzed along with other fungal genomes. Ectomycorrhizal fungi have a reduced complement of genes encoding plant cell wall–degrading enzymes (PCWDEs), as compared to their ancestral wood decayers. Nevertheless, they have retained a unique array of PCWDEs, thus suggesting that they possess diverse abilities to decompose lignocellulose....

Data from: Evolution of novel wood decay mechanisms in Agaricales revealed by the genome sequences of Fistulina hepatica and Cylindrobasidium torrendii

Ransdell, Hina Younus, Julianna Chow, Jennifer Chiniquy, Anna Lipzen, Andrew Tritt, Hui Sun, Sajeet Haridas, Kurt LaButti, Robin A. Ohm, Ursula Kues, Robert A. Blanchette, Igor V. Grigoriev, Robert E. Minto & David S. Hibbett
Wood decay mechanisms in Agaricomycotina have been traditionally separated in two categories termed white and brown rot. Recently the accuracy of such a dichotomy has been questioned. Here, we present the genome sequences of the white rot fungus Cylindrobasidium torrendii and the brown rot fungus Fistulina hepatica both members of Agaricales, combining comparative genomics and wood decay experiments. Cylindrobasidium torrendii is closely related to the white-rot root pathogen Armillaria mellea, while F. hepatica is related...

Data from: Multiple maize reference genomes impact the identification of variants by GWAS in a diverse inbred panel

Use of a single reference genome for genome-wide association studies (GWAS) limits the gene space represented to that of a single accession. This limitation can complicate identification and characterization of genes located within presence/absence variations (PAVs). In this study, we present the draft de novo genome assembly of PHJ89, an Oh43-type inbred line. Using three separate reference genome assemblies (B73, PH207, and PHJ89) that represent the predominant germplasm groups of maize, we generated three separate...

Data from: Extensive genetic diversity is present within North American switchgrass germplasm

Kaeppler, E. Charles Brummer, Michael D. Casler & C. Robin Buell
Switchgrass (Panicum virgatum L.) is a perennial native North American grass present in two ecotypes: upland, found primarily in the northern range of switchgrass habitats, and lowland, found largely in the southern reaches of switchgrass habitats. Previous studies focused on a diversity panel of primarily northern switchgrass, so to expand our knowledge of genetic diversity in a broader set of North American switchgrass, exome capture sequence data were generated for 632 additional, primarily lowland individuals....

Data from: Diel rewiring and positive selection of ancient plant proteins enabled evolution of CAM photosynthesis in Agave

Background: Crassulacean acid metabolism (CAM) enhances plant water-use efficiency through an inverse day/night pattern of stomatal closure/opening that facilitates nocturnal CO2 uptake. CAM has evolved independently in over 35 plant lineages, accounting for ~ 6% of all higher plants. Agave species are highly heat- and drought-tolerant, and have been domesticated as model CAM crops for beverage, fiber, and biofuel production in semi-arid and arid regions. However, the genomic basis of evolutionary innovation of CAM in...

Tracking the ancestry of known and ‘ghost’ homeologous subgenomes in model grass Brachypodium polyploids

Rubén Sancho, Luis Ángel Inda, Antonio Díaz-Pérez, David L Des Marais, Sean Gordon, John Vogel, Joanna Lusinska, Robert Hasterok, Bruno Contreras-Moreira & Pilar Catalán
Unraveling the evolution of plant polyploids is a challenge when their diploid progenitor species are extinct or unknown or when genome sequences of known progenitors are unavailable. Existing subgenome identification methods cannot adequately infer the homeologous genomes that are present in the allopolyploids if they do not take into account the potential existence of unknown progenitors. We addressed this challenge in the widely distributed dysploid grass genus Brachypodium, which is a model genus for temperate...

HT-SIP: a semi-automated stable isotope probing pipeline identifies cross-kingdom interactions in the hyphosphere of arbuscular mycorrhizal fungi

Erin E. Nuccio, Steven J. Blazewicz, Marissa Lafler, Ashley N. Campbell, Anne Kakouridis, Jeffrey A. Kimbrel, Jessica Wollard, Dariia Vyshenska, Robert Riley, Andy Tomatsu, Rachel Hestrin, Rex R. Malmstrom, Mary Firestone & Jennifer Pett-Ridge
Abstract Background Linking the identity of wild microbes with their ecophysiological traits and environmental functions is a key ambition for microbial ecologists. Of many techniques that strive for this goal, Stable-isotope probing—SIP—remains among the most comprehensive for studying whole microbial communities in situ. In DNA-SIP, actively growing microorganisms that take up an isotopically heavy substrate build heavier DNA, which can be partitioned by density into multiple fractions and sequenced. However, SIP is relatively low throughput...

Guy, Yousry A. El-Kassaby, Shawn D. Mansfield … & Gerald A. Tuskan
Genetic mapping of quantitative traits requires genotypic data for large numbers of markers in many individuals. For such studies, the use of large single nucleotide polymorphism (SNP) genotyping arrays still offers the most cost-effective solution. Herein we report on the design and performance of a SNP genotyping array for Populus trichocarpa (black cottonwood). This genotyping array was designed with SNPs pre-ascertained in 34 wild accessions covering most of the species latitudinal range. We adopted a...

Data from: Generation of transcript assemblies and identification of single nucleotide polymorphisms from seven lowland and upland cultivars of switchgrass

Kevin L. Childs, Aruna Nandety, Candice N. Hirsch, Elsa Góngora-Castillo, Jeremy Schmutz, Shawn M. Kaeppler, Michael D. Casler & C. Robin Buell
Switchgrass (Panicum virgatum) is a North American perennial prairie species that has been used as a rangeland and forage crop and has recently been targeted as a potential biofuel feedstock species. Switchgrass, which occurs as tetraploid and octoploid forms, is classified into lowland or upland ecotypes that differ in growth phenotypes and adaptation to distinct habitats. Using RNA-sequencing reads derived from crown, young shoot and leaf tissues, we generated sequence data from seven switchgrass cultivars,...

Data from: Insights into the maize pan-genome and pan-transcriptome

Candice N. Hirsch, Jillian M. Foerster, James M. Johnson, Rajandeep S. Sekhon, German Muttoni, Brieanne Vaillancourt, Francisco Peñagaricano, Erika Lindquist, Mary Ann Pedraza, Kerrie Barry, Natalia De Leon, Shawn M. Kaeppler & C. Robin Buell
Genomes at the species level are dynamic, with genes present in every individual (core) and genes in a subset of individuals (dispensable) that collectively constitute the pan-genome. Using transcriptome sequencing of seedling RNA from 503 maize (Zea mays) inbred lines to characterize the maize pan-genome, we identified 8681 representative transcript assemblies (RTAs) with 16.4% expressed in all lines and 82.7% expressed in subsets of the lines. Interestingly, with linkage disequilibrium mapping, 76.7% of the RTAs...

Szarkándi, Viktor Papp, László Albert, William Andreopoulos, Claudio Angelini, Vladimír Antonín, Kerrie W. Barry, Neale L. Bougher, Peter Buchanan, Bart Buyck, Viktória Bense, Pam Catcheside, Mansi Chovatia, Jerry Cooper, Wolfgang Dämon, Dennis Desjardin, Péter Finy, József Geml … & László G. Nagy
Mushroom-forming fungi (Agaricomycetes) have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfill diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. Despite the importance of mushroom-forming fungi, large-scale patterns of their evolutionary history are poorly known, in part due to the lack of a comprehensive and dated molecular phylogeny. Here, using multigene and genome-based data, we assemble a 5,284-species phylogenetic tree...

Nolan Bornowski, Kathryn J. Michel, John P. Hamilton, Shujun Ou, Arun S. Seetharam, Jerry Jenkins, Jane Grimwood, Chris Plott, Shengqiang Shu, Jayson Talag, Megan Kennedy, Hope Hundley, Vasanth R. Singan, Kerrie Barry, Chris Daum, Yuko Yoshinaga, Jeremy Schmutz, Candice N. Hirsch, Matthew B. Hufford, Natalia De Leon, Shawn M. Kaeppler & C. Robin Buell
The Stiff Stalk heterotic group is an important source of inbreds used in U.S. commercial hybrid production. Founder inbreds B14, B37, B73, and to a lesser extent B84, are found in the pedigrees of a majority of commercial seed parent inbred lines. We created high-quality genome assemblies of B84 and four ex-Plant Variety Protection lines LH145 representing B14, NKH8431 of mixed descent, PHB47 representing B37, and PHJ40 which is a Pioneer Hi-Bred early Stiff Stalk...

Supporting data for: Gene-rich UV sex chromosomes harbor conserved regulators of sexual development (Carey et al., 2021)

Sarah Carey, Shenqiang Shu, John Lovell, Avinash Shenqiang, Florian Maumus, George Tiley, Noe Fernandez-Pozo, Kerrie Barry, Cindy Chen, Mei Wang, Anna Lipzen, Chris Daum, Christopher Saski, Adam Payton, Jordan McBreen, Roth Conrad, Leslie Kollar, Sanna Olsson, Sanna Huttunen, Jacob Landis, Norman Wickett, Matthew Johnson, Stefan Rensing, Jane Grimwood, Jeremy Schmutz … & Adam Healey
Non-recombining sex chromosomes, like the mammalian Y, often lose genes and accumulate transposable elements, a process termed degeneration. The correlation between suppressed recombination and degeneration is clear in animal XY systems, but the absence of recombination is confounded with other asymmetries between the X and Y. In contrast, UV sex chromosomes, like those found in bryophytes, experience symmetrical population genetic conditions. Here we generate and use nearly gapless female and male chromosome-scale reference genomes of...

Genome sequencing of spatially distributed individuals sheds light on how evolution structures genetic variation. Populations of Phellopilus nigrolimitatus, a red-listed wood-inhabiting fungus associated with old-growth coniferous forests, have decreased in size over the last century due to a loss of suitable habitats. We assessed the population genetic structure and investigated local adaptation in P. nigrolimitatus, by establishing a reference genome and genotyping 327 individuals sampled from 24 locations in Northern Europe by RAD sequencing. We...
