13. Estudos realizados com o virus do mosaico dourado do feijoeiro do Brasil visando sua transmissão por metodos mecanicos
Bean golden mosaic virus in Brazil has not been transmitted mechanically by investigators that have tried it. Other related viruses associated with similar diseases present in Central America, Porto Rico, and Colombia have been transmitted by routine methods of mechanical inoculation without great difficulty. This apparent discrepancy led the writer to start

14. The N gene of tobacco confers resistance to tobacco mosaic virus in transgenic tomato.
It has been proposed that cloned plant disease resistance genes could be transferred from resistant to susceptible plant species to control important crop plant diseases. The recently cloned N gene of tobacco confers resistance to the viral pathogen, tobacco mosaic virus. We generated transgenic tomato plants bearing the N gene and demonstrate that N confers

15. Plant viral synergism: the potyviral genome encodes a broad-range pathogenicity enhancer that transactivates replication of heterologous viruses.
Synergistic viral diseases of higher plants are caused by the interaction of two independent viruses in the same host and are characterized by dramatic increases in symptoms and in accumulation of one of the coinfecting viruses. In potato virus X (PVX)/potyviral synergism, increased pathogenicity and accumulation of PVX are mediated by the expression of poty
