Impact of climate change on molecular interactions between the soybean cyst nematode (Heterodera glycines) and its main host, soy (Glycine max)
In Canada, the soybean cyst nematode, Heterodera glycines (SCN), was first detected in Ontario in 1988 and more recently in Quebec in 2013. It is the main cause of economic loss associated with soy production in Canada and the United States. Control methods against this pest are limited and mostly rely on soy’s natural resistance genes. It is essential to study the response of the SCN and that of its host under Quebec’s climate in order to develop effective control strategies. Moreover, the temperature fluctuations associated with climate change will modify SCN’s biological characters, its host’s phenology, and their interaction. This could affect both the efficacy and durability of management tools. In this context, the impact of the anticipated climate change on the interactions between the soybean cyst nematode and its principal host, soy, will be presented.
