This dataset contains a single whole-genome optical map file (.CMAP) for bread wheat (Triticum aestivum) cv Chinese Spring (CS). The methods for constructing this optical map and the properties of this map are described below. The definition of the CMAP format is documented in https://bionanogenomics.com/wp-content/uploads/2017/03/30039-CMAP-File-Format-Specification-Sheet.pdf. The extracted ultra-high-molecular weight DNA molecules of CS were labeled with the DLE-1 enzyme (Bionano Genomics, San Diego, CA, USA) and were then stained with the Bionano PrepTM DLS Kit...

Aim: If we are able to determine the geographic origin of an invasion, as well as its known area of introduction, we can better appreciate the innate environmental tolerance of a species and the strength of selection for adaptation that colonising populations have undergone. It also enables us to maximise the success of searches for effective biological control agents. We determined the number of successful colonisation events that have occurred throughout the world for two...
