Adaptive constraints at the range edge of a widespread and expanding invasive plant Open
Identifying the factors that facilitate and limit invasive species’ range expansion has both practical and theoretical importance, especially at the range edges. Here, we used reciprocal common garden experiments spanning the North/South a…
Genetic dissection of morphological variation between cauliflower and a rapid cycling <i>Brassica oleracea</i> line Open
To improve resolution to small genomic regions and sensitivity to small-effect loci in the identification of genetic factors conferring the enlarged inflorescence and other traits of cauliflower while also expediting further genetic dissec…

Exploiting genetic variation from unadapted germplasm—An example from improvement of sorghum in Ethiopia Open
Societal Impact Statement The productivity of sorghum in Ethiopia has been largely limited by rain‐fed conditions because farmers tend to use local drought‐tolerant but low‐yielding landraces, as high‐yielding and late‐maturing landrace cu…

Unraveling the genetic components of perenniality: Toward breeding for perennial grains Open
Social Impact Statement Although tremendously successful at feeding humanity, row crop agriculture based on annuals contributes to numerous ecosystem dis‐services, ranging from soil degradation and aquatic eutrophication to greenhouse gas …

Natural variation further increases resilience of sorghum bred for chronically drought-prone environments Open
Climate-change-associated shifts in rainfall distribution together with a looming worldwide water crisis make drought resilience of central importance to food security. Even for relatively drought resilient crops such as sorghum, moisture …

New adaptive peaks for crops – an example from improvement of drought-resilience of sorghum in Ethiopia Open
Summary As the center of diversity for sorghum [ Sorghum bicolor (L.) Moench], elite cultivars selected in Ethiopia are of central importance to sub-Saharan food security. Despite being presumably well adapted to their center of diversity,…
Comparative evolution of vegetative branching in sorghum Open
Tillering and secondary branching are two plastic traits with high agronomic importance, especially in terms of the ability of plants to adapt to changing environments. We describe a quantitative trait analysis of tillering and secondary b…
Transmission Genetics of a Sorghum bicolor × S. halepense Backcross Populations Open
Despite a "ploidy barrier," interspecific crosses to wild and/or cultivated sorghum (Sorghum bicolor, 2n = 2x = 20) may have aided the spread across six continents of Sorghum halepense, also exemplifying risks of "transgene escape" from cr…
Genotyping by Sequencing of 393 <i>Sorghum bicolor</i> BTx623 × IS3620C Recombinant Inbred Lines Improves Sensitivity and Resolution of QTL Detection Open
We describe a genetic map with a total of 381 bins of 616 genotyping by sequencing (GBS)-based SNP markers in a F6-F8 recombinant inbred line (RIL) population of 393 individuals derived from crossing S. bicolor BTx623 to S. bicolor IS3620C…

Multi-Phase US Spread and Habitat Switching of a Post-Columbian Invasive, Sorghum halepense Open
Johnsongrass (Sorghum halepense) is a striking example of a post-Columbian founder event. This natural experiment within ecological time-scales provides a unique opportunity for understanding patterns of continent-wide genetic diversity fo…
