A full length cDNA copy of the genomic RNA of lettuce mosaic virus (LMV) was constructed under the control of an enhanced CaMV 35S promoter and of the NOS terminator. This construct was found infectious when inoculated to lettuce plants. The intron II of the bean nitrite reductase gene was engineered into the LMV FL cDNA in order to relieve possible deleterious effects of viral sequences to Escherichia coli cells and to evaluate the effects of the presence of the intron on the FL cDNA infectivity. The intron-less FL cDNA was found to be as stable as its intron-containing counterpart in E. coli. Sequence analysis of progeny RNA derived from plants inoculated with the intron-containing FL cDNA demonstrated that the inserted intron was perfectly spliced out. The symptoms induced in lettuce by either the intron-less or the intro-containing constructs were identical to those caused by the wild-type virus. However a slight delay in the establishment of infection in lettuce and a more obvious lag in Nicotiana benthamiana were observed with the intron-containing FL cDNA.
