Abstract

There is much talk today about global warming, and the latest assessment report of the Intergovernmental Panel on Climate Change has brought numerical evidence of the occurrence of changes in our atmosphere.The rise of temperature directly affects agriculture on a global level, whereas it influences the environment in which plant interactions with herbivores and pathogens occur.An example of this is plant diseases that have become important in places where they were not relevant or have the potential to do so if climate change intensifies. In this context, the rust group has shown increasing potential and relevance, such as soybean rust in the United States and wheat rust in Europe.Experiments with Phakopsora euvitis on vines (Vitis labrusca L.) 'Niagara Rosada', conducted by our team, have raised new questions about this plant-pathogen interaction. At temperatures of 20 to 25 ° C there is high germination rate of urediniospores and high severity, and at 30 ° C, even with the low germination of urediniospores, there is high severity, with the presence of necrosis. An intriguing fact, not only because of the absence of the relationship between spore germination rate and disease efficiency, but also due to the appearance of necrosis, hypersensitivity response, which is commonly associated with low severity. The aim of the proposal is to identify the changes caused by temperature in the plant-pathogen relationship between Phakopsora euvitis and two grapevine species, V. labrusca 'Niagara Rosada' and V. vinifera ' Cabernet '.
