Infectivity of in vitro transcripts of Johnsongrass mosaic potyvirus full-length cDNA clones in maize and sorghum

In vitro transcripts of full-length cDNA clones of the Johnsongrass strain of Johnsongrass mosaic potyvirus (JGMV-Jg) were infectious on maize and sorghum when inoculated by mechanical or by biolistic bombardment. Two of the cDNA clones with spontaneous mutations in the coat protein were not infecti...
