aF, viral RNA from CMV-Fny; Z, viral RNA from the CMV-ZMBJ; FZ, chimeric viral RNA with 5′UTR and MP gene from Fny-RNA3 and CP gene and 3′-UTR from ZMBJ-RNA3; and ZF, chimeric viral RNA with 5′-UTR and MP gene from ZMBJ-RNA3 and CP gene and 3′-UTR from Fny-RNA3.
bAll of the inoculated plants were analyzed by western blotting from three independent experiments. The number of plants infected/the number of plants inoculated is indicated in the parenthesis.
