Shifts in the abiotic and biotic environment of cultivated sunflower under future climate change
Sunflower is a unique model species for assessing crop responses and adaptation to climate change. We provide an initial assessment of how climate change may influence the abiotic and biotic environment of cultivated sunflower across the world. We find an 8% shift between current and future climate space in cultivated...Mehrabi, Zia ; Pironon, Samuel ; Kantar, Michael ; Ramankutty, Navin ; Rieseberg, Loren

A customized nuclear target enrichment approach for developing a phylogenomic baseline for Dioscorea yams (Dioscoreaceae)
Premise We developed a target enrichment panel for phylogenomic studies of Dioscorea, an economically important genus with incompletely resolved relationships. Methods Our bait panel comprises 260 low- to single-copy nuclear genes targeted to work in Dioscorea, assessed here using a preliminary taxon sampling that includes both distantly and closely related...Soto Gomez, Marybel ; Pokorny, Lisa ; Kantar, Michael ; Forest, Félix ; Leitch, Ilia …

A Target Capture-Based Method to Estimate Ploidy From Herbarium Specimens
Whole genome duplication (WGD) events are common in many plant lineages, but the ploidy status and possible occurrence of intraspecific ploidy variation are unknown for most species. Standard methods for ploidy determination are chromosome counting and flow cytometry approaches. While flow cytometry approaches typically use fresh tissue, an increasing number...Viruel, Juan ; Conejero, María ; Hidalgo, Oriane ; Pokorny, Lisa ; Powell, Robyn …
