Dear Mycovirus Researchers,

This is the second circular for the forthcoming Third International Mycovirus Symposium being organized by Angus Dawe DAWE, Nobuhro Suzuki and Bradley Hillman, comprising the organizing committee, are pleased to inform you of the forthcoming Third International Mycovirus Symposium. We are pleased to inform you that three great scientists Drs. Don Nuss, Said Ghabrial and Reed Wickner, who have been leading the field, accepted our invitation to deliver keynote lectures. Other confirmed speakers (PIs) are also listed below. We shall be able to learn a lot more about mycoviruses and prions from them. It is not too late to sign up for the symposium on line. We would greatly appreciate it if you could encourage your colleagues to do so.


The venue has now been fixed to University of Vermont (please see the attached file for UVM overnight accommodation). Further information on the symposium arrangements will be available at our web site. For those of you who did not receive the first circular, please visit the site. Please start visa preparation now for those of you are required to enter USA and/or Canada. We, as the symposium organizer, would be happy to provide you an invitation letter if necessary.
