Abstract

SUMMARY

Neither tobacco mesophyll protoplasts nor tobacco leaves could be infected with wild type brome mosaic virus (BMV ) or its RNA, but both were infected when inoculated with 50 µg/ml or more of a variant of BMV (BMV ). This is about 100 × the amount required for efficient infection by cowpea chlorotic mottle virus (CCMV). Poly--ornithine stimulated the infection of protoplasts with BMV , but was not essential. BMV . RNA inoculum caused infection of protoplasts under conditions similar to those needed for their infection with CCMV-RNA.
