Plant viruses transmitted by vectors (226416)
The main objective of course is to give Knowledge about different plant viruses that are transmitted by vectors (fungi, pseudofungi, insects, mites, nematodes). Through the course students will learn about structure, ecology and epidemiology of economically most important plant viruses which vectors are mentioned organisms, learn about virus-vector-plant interactions that are happening on molecular level and possibilities of their control or slowing down their spread.
