OSTI ID:5770239

During the last year we have made a number of important observations in the fields of virology and plant molecular biology. By directly sequencing Tomato Mosaic Virus (ToMV) movement genes, previously undetected sequence alterations common to specific viral strains were found. The difficulty in regenerating transgenic tomato plants containing the Tm-2 gene was overcome. Tobacco plants transformed with Cucumber Mosaic Virus (CMV) are being characterized. Analysis of transgenic tobacco plants expressing CMV coat protein have shown no correlation between coat protein expression and level of resistance. Specific amino acid changes have been found to correlate with CMV resistance breaking and degree of pathogenicity. Satellite RNAs are shown to be too unstable for use as a biological control agent. The aphid transmission domain CMV has been localized to one (or more) of three amino acids; constructs have been made to determine the exact amino acids involved. 15 refs.
