in leaves systemically inoculated with tmv using a differential temperature inoculation procedure to synchronize the infection , 1 mm 2-thiouracil inhibited viral protein and rna synthesis totally when treatment began within the first 4 h after initiation of replication , but not at all when treatment began at 12 h or later , even though earlier reports had shown that most rna and protein synthesis occurred after 12 h .
