Abstract
SUMMARY: The major disease affecting Dioscorea cayenensis in the Ivory Coast is caused by a virus which was transmitted by mechanical inoculation to some Dioscorea spp. and Nicotiana benthamiana. In extracts of D. cayenensis leaves infectivity was lost after 10 min at 60 d̀C but not 55 d̀C and after dilution to 10‐3 but not 10‐2. A purification procedure is described. The virus particles are flexuous filaments c. 785 nm long. The virus was transmitted by four aphid species in the non‐persistent manner, and is serologically related to four African potyviruses. The name yam mosaic virus is proposed; the present cryptogram is: */*:*/6:E/E:S/Ve/Ap, potyvirus group.This publication has 3 references indexed in Scilit:
