Journal ArticleDOI
Ethylene-insensitive tobacco lacks nonhost resistance against soil-borne fungi
M. Knoester,Leendert C. van Loon,Joop van den Heuvel,Jacek Hennig,John F. Bol,Huub J. M. Linthorst +5 more
TL;DR: Tobacco plants were transformed with the mutant etr1-1 gene from Arabidopsis, conferring dominant ethylene insensitivity, but these transformants did not slow growth when contacting neighboring plants, hardly expressed defense-related basic pathogenesis-related proteins, and developed spontaneous stem browning.
Journal ArticleDOI
Differential induction of acquired resistance and PR gene expression in tobacco by virus infection, ethephon treatment, UV light and wounding.
TL;DR: Increased levels of resistance to TMV, comparable to resistance obtained by pre-infection with the virus, were found in UV-irradiated leaves but not in wounded or ethephon-treated leaves, which indicates that the basic PR proteins are not involved in resistance toTMV infection.
Journal ArticleDOI
Overproduction of salicylic acid in plants by bacterial transgenes enhances pathogen resistance
Marianne C. Verberne,Robert Verpoorte,John F. Bol,Jesús Mercado-Blanco,Jesús Mercado-Blanco,Huub J. M. Linthorst +5 more
TL;DR: Tobacco is transformed with two bacterial genes coding for enzymes that convert chorismate into SA by a two-step process and the CSA plants showed a resistance to viral and fungal infection resembling SAR in nontransgenic plants.
Journal ArticleDOI
A tobacco mosaic virus-induced tobacco protein is homologous to the sweet-tasting protein thaumatin
TL;DR: The cDNA cloning of another mRNA whose synthesis is induced by TMV infection showed that the encoded protein is highly homologous to thaumatin, the intensely sweet-tasting protein from the fruits of the monocot Thaumatococcus daniellii Benth, a West African rainforest shrub.
Journal ArticleDOI
The complete nucleotide sequence of potato virus X and its homologies at the amino acid level with various plus-stranded RNA viruses.
TL;DR: Double-stranded cDNA of potato virus X (PVX) genomic RNA has been cloned and sequenced and revealed five open reading frames (ORFs) which encoded proteins of Mr 165588 (166K), 24622 (25K), 12324 (12K), 7595 (8K) and 25080 (coat protein), respectively.
