Stage-Related Defense Response Induction in Tomato Plants by Nesidiocoris tenuis

The beneficial effects of direct predation by zoophytophagous biological control agents (BCAs), such as the mirid bug Nesidiocoris tenuis, are well-known. However, the benefits of zoophytophagous BCAs' relation with host plants, via induction of plant defensive responses, have not been investigated until recently. To date, only the females of certain zoophytophagous BCAs have been demonstrated ...

Tumorigenesis on mineral-deficient tomato plants.

SUMMARY Tumor morphogenesis on stems of Lycopersicon eseulen turn, variety Rutgers initiated by Agrobacterium tumefaciens varies with the absence of certain elements from the nutrient solutions. Examinations of the tumors on plants grown in complete and incomplete nutrient solutions revealed different quantities and sizes of vessel elements as well as differences in the quantities of soluble pr...

Effect of water activity and temperature on growth of Alternaria alternata on a synthetic tomato medium.

Alternaria alternata is a toxigenic fungus, predominantly responsible for Blackmould of ripe tomato fruits, a disease frequently causing substantial losses of tomatoes, especially those used for canning. The objective of this study was to determine the effect of water activity (a(w), 0.904, 0.922, 0.954, 0.982) and temperature (6, 15, 21 and 35 degrees C) on germination and radial growth rate o...

Multiple phytohormone signalling pathways modulate susceptibility of tomato plants to Alternaria alternata f. sp. lycopersici

Three phytohormone molecules - ethylene (ET), jasmonic acid (JA) and salicylic acid (SA) - play key roles in mediating disease response to necrotrophic fungal pathogens. This study investigated the roles of the ET, JA, and SA pathways as well as their crosstalk during the interaction between tomato (Solanum lycopersicum) plants and a necrotrophic fungal pathogen Alternaria alternata f. sp. lyco...

Tomato Plants

as a diagnostic probe for P. syringae pv. tomato. In a survey of 75 plant-associated bacteria, pTPR1 hybridized exclusively to those strains that produced coronatine. The detection limit for this probe, which was labeled with the Chemiprobe nonradioactive reporter system, was approximately 4 x 103 CFU of lesion bacteria. During the 1989 growing season, a total of 258 leaf and fruit lesions from...
