Background: The yellow potato cyst nematode Globodera rostochiensis is a devastating plant pathogen of global economic importance. This biotrophic parasite secretes effectors from pharyngeal glands, some of which were acquired by horizontal gene transfer, to manipulate host processes and promote parasitism. G. rostochiensis is classified into pathotypes with different plant resistance-breaking phenotypes. Results: We generate a high-quality genome assembly for G. rostochiensis pathotype Ro1, identify putative effectors and horizontal gene transfer events, map gene expression...

Irreproducibility in searches of scientific literature: a comparative analysis

Gabor Pozsgai, Gabor Lövei, Liette Vasseur, Geoff Gurr, Péter Batáry, Janos Korponai, Nick Littlewood, Jian Liu, Arnold Móra, John Obrycki, Olivia Reynolds, Jenni Stockan, Heather VanVolkenburg, Jie Zhang, Wenwu Zhou & Minsheng You
1. Repeatability is the cornerstone of science and it is particularly important for systematic reviews. However, little is known on how researchers’ choice of database and search platform influence the repeatability of systematic reviews. Here, we aim to unveil how the computer environment and the location where the search was initiated from influence hit results. 2. We present a comparative analysis of time-synchronized searches at different institutional locations in the world, and evaluate the consistency...

Chromosome evolution and the genetic basis of agronomically important traits in greater yam

Jessen Bredeson, Jessica Lyons, Ibukun Oniyinde, Nneka Okereke, Olufisayo Kolade, Ikenna Nnabue, Nneka Okereke, Christian Nwadili, Eva Hribova, Matthew Parker, Jeremiah Nwogha, Shengqiang Shu, Joseph Carlson, Robert Kariba, Samuel Muthemba, Katarzyna Knop, Geoffrey Barton, Anna Sherwood, Antonio Lopez-Montes, Robert Asiedu, Ramni Jamnadass, Alice Muchugi, David Goodstein, Chiedozie Egesi, Jonathan Featherston … & Daniel Rokhsar
The nutrient-rich tubers of the greater yam, Dioscorea alata L., provide food and income security for millions of people around the world. Despite its global importance, however, greater yam remains an ‘orphan crop.’ Here we address this resource gap by presenting a highly contiguous chromosome-scale genome assembly of D. alata combined with a dense genetic map derived from African breeding populations. The genome sequence reveals an ancient allotetraploidization in the Dioscorea lineage, followed by extensive...

Data from: Location, but not defensive genotype, determines ectomycorrhizal community composition in Scots pine (Pinus sylvestris L.) seedlings

Jim Downie, Andy F. S. Taylor, Glenn Iason, Ben Moore, Jonathan Silvertown, Stephen Cavers & Richard Ennos
1. For successful colonisation of host roots, ectomycorrhizal (EM) fungi must overcome host defence systems, and defensive phenotypes have previously been shown to affect the community composition of EM fungi associated with hosts. Secondary metabolites, such as terpenes, form a core part of these defence systems, but it is not yet understood whether variation in these constitutive defences can result in variation in colonisation of hosts by specific fungal species. 2. We planted seedlings from...

Long-term multisite Scots pine single nucleotide polymorphism (SNP) genotypes and phenotypes for marker-trait association analysis

A. Perry, J. Beaton, G. Iason, J. Cottrell, J. Stockan & S. Cavers
This dataset contains data pertaining to the phenotypes (height and budburst) and genotypes (via SNP array) for a subset of trees from a long term multi-site Scots pine experimental trial.

Data from: An exceptionally high nucleotide and haplotype diversity and a signature of positive selection for the eIF4E resistance gene in barley are revealed by allele mining and phylogenetic analyses of natural populations.

In barley, the eukaryotic translation initiation factor 4E (eIF4E) gene situated on chromosome 3H is recognised as an important source of resistance to the bymoviruses Barley yellow mosaic virus and Barley mild mosaic virus. In modern barley cultivars two recessive eIF4E alleles, rym4 and rym5, confer different isolate-specific resistances. In this study the sequence of eIF4E was analysed in 1090 barley landraces and non-current cultivars originating from 84 countries. An exceptionally high nucleotide diversity was...
