Data from: First Report of Squash vein yellowing virus in Watermelon in Guatemala

Watermelon (*Citrullus lanatus*) and other cucurbits are important crops grown in Guatemala for local consumption and export. Four samplings of crowns, peduncles, and/or leaves of symptomatic plants were made in March and April 2015. Total RNA was extracted from symptomatic plant tissue and tested by RT-PCR for SqVYV, CYSDV, PRSV, and/or begomoviruses. This is the first report of SqVYV infecting watermelon in Central America.

Data from: Construction of a High-Density American Cranberry (Vaccinium macrocarpon Ait.) Composite Map Using Genotyping-by-Sequencing for Multi-pedigree Linkage Mapping

To increase the availability of cranberry genomic resources, genotyping-by-sequencing (GBS) was used to discover and genotype thousands of single nucleotide polymorphisms (SNPs) within three interrelated cranberry full-sib populations.

Data from: Similarities among Test Sites Based on the Performance of Advanced Breeding Lines in the Great Plains Hard Winter Wheat Region

Data from USDA-ARS Hard Winter Wheat Regional Nurseries grown in 1987 to 2014 were used to identify similarities in agronomic performance and adaptation of experimental breeding lines among Great Plains test sites.

Data from: Phased Genotyping-by-Sequencing Enhances Analysis of Genetic Diversity and Reveals Divergent Copy Number Variants in Maize

This study supports the notion that genotyping-by-sequencing (GBS) can be tailored to particular aims, and using *Zea mays* results indicate that large samples of unknown pedigree can be genotyped to obtain complete and accurate GBS data. A GBS procedure was established that produces high call rates per marker (>85%) with accuracy exceeding 99.4%.

Data from: Selenium geochemistry in reclaimed phosphate mine soils and its relationship with plant bioavailability

Soil physicochemical properties, Se speciation, and Se distribution from a sequential extraction procedure (SEP) were examined in relation to bioavailability in the Se-hyperaccumulator, western aster (Symphyotrichum ascendens Lindl.), and potential toxicity in livestock grazing on phosphate mine soils in Southeastern Idaho.

Data from: Wild emmer genome architecture and diversity elucidate wheat evolution and domestication

A polyploid wheat genome assembly elucidates wheat domestication history. A 10.1-gigabase assembly of the 14 chromosomes of wild tetraploid wheat is reported, as well as analyses of gene content, genome architecture, and genetic diversity.

Data from: Development and Validation of KASP Markers for Wheat Streak Mosaic Virus Resistance Gene Wsm2

Data from: Proteomics analysis reveals novel host molecular mechanisms associated with thermotherapy of 'Ca. Liberibacter asiaticus'-infected citrus plants

The goal of this study is to identify potential Las resistance/tolerance-related genes in citrus plants for application in breeding or genetic engineering programs, and apply comparative proteomics analysis via 2-DE and mass spectrometry to elucidate the molecular processes associated with heat-induced mitigation of HLB in citrus plants.

Data from: Genetic Architecture of Resistance to Stripe Rust in a Global Winter Wheat Germplasm Collection

Virulence shifts in populations of *Puccinia striiformis* f. sp. *tritici* (*Pst*), the causal pathogen of wheat stripe rust, are a major challenge to resistance breeding. The majority of known resistance genes are already ineffective against current races of *Pst*, necessitating the identification and introgression of new sources of resistance. Germplasm core collections that reflect the range of genetic and phenotypic diversity of crop species are ideal platforms for examining the genetic architecture of complex traits such as resistance to stripe rust. We report the results of genetic characterization and genome-wide association analysis (GWAS) for resistance to stripe rust in a core subset of 1175 accessions in the National Small Grains Collection (NSGC) winter wheat germplasm collection, based on genotyping with the wheat 9K single nucleotide polymorphism (SNP) iSelect assay and phenotyping of seedling and adult plants under natural disease epidemics in four environments.
