Data from: Genetic Diversity and Population Structure of the USDA Sweetpotato (Ipomoea batatas) Germplasm Collections Using GBSpoly

Population structure and genetic diversity of 417 USDA sweetpotato (*Ipomoea batatas*) accessions originating from 8 broad geographical regions (Africa, Australia, Caribbean, Central America, Far East, North America, Pacific Islands, and South America) were determined using single nucleotide polymorphisms (SNPs) identified with a genotyping-by-sequencing (GBS) protocol, GBSpoly, optimized for highly heterozygous and polyploid species.

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.
