TY - JOUR T1 - Possible Role Of Fungal Viruses in the Distribution and Spread Of the Dutch Elm Disease Fungus JF - Arboriculture & Urban Forestry (AUF) SP - 230 LP - 232 DO - 10.48044/jauf.1981.057 VL - 7 IS - 9 AU - P. Lawrence Pusey AU - Charles L. Wilson Y1 - 1981/09/01 UR - http://auf.isa-arbor.com/content/7/9/230.abstract N2 - Double-stranded RNA, which is characteristic of fungal viruses, has been detected previously in isolates of Ceratocystis ulmi. Isolates from states with a long history of Dutch elm disease contained dsRNA, whereas isolates from states with a short history of the disease had no dsRNA. It is suggested that fungal viruses may be a factor in the distribution and spread of C. ulmi. ER -
