Data from: Testing the impact of calibration on molecular divergence times using a fossil-rich group: the case of Nothofagus (Fagales)

Hervé Sauquet, Simon Y. W. Ho, Maria A. Gandolfo, Gregory J. Jordan, Peter Wilf, David J. Cantrill, Michael J. Bayly, Lindell Bromham, Gillian K. Brown, Raymond J. Carpenter, Daphne M. Lee, Daniel J. Murphy, J. M. Kale Sniderman & Frank Udovicic
Although temporal calibration is widely recognized as critical for obtaining accurate divergence-time estimates using molecular dating methods, few studies have evaluated the variation resulting from different calibration strategies. Depending on the information available, researchers have often used primary calibrations from the fossil record or secondary calibrations from previous molecular dating studies. In analyses of flowering plants, primary calibration data can be obtained from macro- and mesofossils (e.g., leaves, flowers, and fruits) or microfossils (e.g., pollen)....

Data from: Interspecific hybridization transfers a previously unknown glyphosate resistance mechanism in Amaranthus species

Todd A Gaines, Sarah M Ward, Bekir Bukun, Christopher Preston, Jan E Leach & Philip Westra
A previously unknown glyphosate resistance mechanism, amplification of the 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) gene, was recently reported in Amaranthus palmeri. This evolved mechanism could introgress to other weedy Amaranthus species through interspecific hybridization, representing an avenue for acquisition of a novel adaptive trait. The objective of this study was to evaluate the potential for this glyphosate resistance trait to transfer via pollen from A. palmeri to five other weedy Amaranthus species (A. hybridus, A. powellii,...

Data from: Rise of the machines – recommendations for ecologists when using next generation sequencing for microsatellite development.

Michael G Gardner, Alison J Fitch, Terry Bertozzi & Andrew J Lowe
Next generation sequencing (NGS) is revolutionizing molecular ecology by simplifying the development of molecular genetic markers, including microsatellites. Here we summarize the results of the large scale development of microsatellites for 54 non-model species using NGS and show there are clear differences amongst plants, invertebrates and vertebrates for the number and proportion of motif types recovered that are able to be utilised as markers. We highlight that the heterogeneity within each group is very large....
