Durum wheat is an economically important crop for Canadian farmers. Fusarium head blight (FHB) is one of the most destructive diseases that threatens durum production in Canada. FHB reduces yield and end-use quality and most commonly contaminates the grain with the fungal mycotoxin deoxynivalenol, also known as DON. Serious outbreaks of FHB can occur in durum wheat in Canada, and combining...

Flagellar motility is considered an important virulence factor in different pathogenic bacteria. In Listeria monocytogenes the transcriptional repressor MogR regulates motility in a temperature-dependent manner, directly repressing flagellar- and chemotaxis genes. The only other bacteria known to carry a mogR homolog are members of the Bacillus cereus group, which includes motile species such as...

Dispersal limitation is cited as the driver of biogeography in archipelagic Southeast Asia. Could environmental filtering play an equally important role? From west to east across the archipelago there are three bioregions: Sunda, Wallacea and Sahul. Historic spatial separation of Sunda and Sahul is thought to limit species exchange. Here, I hypothesise that the Wallacean environment may be too...
