A survey of grapevine fanleaf nepovirus isolates for the presence of satellite RNA

Grapevine fanleaf virus (GFLV) isolates from different geographical origins were surveyed for natural occurrence of satellite RNA. The results of molecular hybridization assays indicated that 5 isolates out of 34 tested, support the multiplication of a satellite RNA, both in Chenopodium quinoa and grapevine. The satellite molecules appear to have a high degree of sequence homology with, and the same size of, the satellite RNA supported by GFLV-F13 strain, isolated and characterized in France
