Data from: Population structure and reticulate evolution of Saccharomyces eubayanus and its lager-brewing hybrids

David Peris, Kayla Sylvester, Diego Libkind, Paula Gonçalves, José Paulo Sampaio, William G. Alexander & Chris Todd Hittinger
Reticulate evolution can be a major driver of diversification into new niches, especially in disturbed habitats and at the edges of ranges. Industrial fermentation strains of yeast provide a window into these processes, but progress has been hampered by a limited understanding of the natural diversity and distribution of Saccharomyces species and populations. For example, lager beer is brewed with Saccharomyces pastorianus, an alloploid hybrid of S. cerevisiae and S. eubayanus, a species only recently...

Data from: Nucleotide polymorphism and copy number variant detection using exome capture and next generation sequencing in the polyploid grass Panicum virgatum

Switchgrass (Panicum virgatum) is a polyploid, outcrossing grass species native to North America and has recently been recognized as a potential biofuel feedstock crop. Significant phenotypic variation including ploidy is present across the two primary ecotypes of switchgrass, referred to as upland and lowland switchgrass. The tetraploid switchgrass genome is approximately 1400 Mbp, split between two subgenomes, with significant repetitive sequence content limiting the efficiency of re-sequencing approaches for determining genome diversity. To characterize genetic...

Data from: Avoided heat-related mortality through climate adaptation in three US cities

, Jason Vargo, Peng Liu, Dana Habeeb, Anthony DeLucia, Marcus Trail, Yongtao Hu, Armistead Russell & Brian Stone
Heat-related mortality in US cities is expected to more than double by the mid-to-late 21st century. Rising heat exposure in cities is projected to result from: 1) climate forcings from changing global atmospheric composition; and 2) local land surface characteristics responsible for the urban heat island effect. The extent to which heat management strategies designed to lessen the urban heat island effect could offset future heat-related mortality remains unexplored in the literature. Using coupled global...

Data from: Hallauer's Tusón: a decade of selection for tropical- to-temperate phenological adaptation in maize

Juliana E. C. Teixeira, Teclemariam Weldekidan, Natalia De Leon, Sherry Flint-Garcia, James B. Holland, Nick Lauter, Seth C. Murray, Wenwei Xu, David A. Hessel, Adrienne E. Kleintop, James A. Hawk, Arnel R. Hallauer & Randall J. Wisser
Crop species exhibit an astounding capacity for environmental adaptation, but genetic bottlenecks resulting from intense selection for adaptation and productivity can lead to a genetically vulnerable crop. Improving the genetic resiliency of temperate maize depends upon the use of tropical germplasm, which harbors a rich source of natural allelic diversity. Here, the adaptation process was studied in a tropical maize population subjected to 10 recurrent generations of directional selection for early flowering in a single...

Data from: Population dynamics of a northern-adapted mammal: disentangling the influence of predation and climate change

John W. Pokallus, Jonathan N. Pauli &
Community structure and interspecific interactions are particularly vulnerable to rapidly changing climatic regimes. Recent changes in both climate and vertebrate community assemblages have created a unique opportunity to examine the impacts of two dynamic forces on population regulation. We examined the effects of warming winter conditions and the reestablishment of a previously extirpated predator, the fisher (Martes pennanti), on regulatory mechanisms in a northern-adapted mammal, the porcupine (Erethizon dorsatum), along their southern range boundary. Using...

Data from: Defining the role of Prolamin-box binding factor1 gene during maize domestication

Zhihong Lang, David M. Wills, Zachary H. Lemmon, Laura M. Shannon, Robert Bukowski, Yongrui Wu, Joachim Messing & John F. Doebley
The prolamin-box binding factor1 (pbf1) gene encodes a transcription factor that controls the expression of seed storage protein (zein) genes in maize. Prior studies show that pbf1 underwent selection during maize domestication although how it affected trait change during domestication is unknown. To assay how pbf1 affects phenotypic differences between maize and teosinte, we compared nearly isogenic lines (NILs) that differ for a maize versus teosinte allele of pbf1. Kernel weight for the teosinte NIL...
