Tomato has been a good model plant to analyze plant-pathogen interactions and its prospects for the future are promising. An international consortium named International Solanaceae Genomics Project (SOL) is proceeding with whole genome sequencing of tomato. In order to be relevant in the post-genomic era, accumulation of information on tomatopathogen interactions is important. In this review, t...

in this research, the effect of using vermicompost on growth rate, fertility and characteristics oftomatoes has been studied. four vermicompost: soil mixture were supplied with ratios of 1:1, 1:2, 1:3, and 1:4 and also four different beds were provided. total of 24 small globe tomato plants were tested and in each bed combination, six tomato plants were embedded. rate of growth and yielding of ...

Plant residues of broccoli, melon, and tomato with or without addition of chicken manure were used as biofumigants in two pot experiments with Meloidogyne incognita-infested soils. The efficacy of these biofumigants in controlling M. incognita infestation in susceptible tomato bio-assay plants was studied at soil temperatures of 20 masculine, 25 masculine, and 30 masculineC. None of the plant r...

The importance of plant volatiles in mediating interactions between plant species is much debated. Here, we demonstrate that the parasitic plant Cuscuta pentagona (dodder) uses volatile cues for host location. Cuscuta pentagona seedlings exhibit directed growth toward nearby tomato plants (Lycopersicon esculentum) and toward extracted tomato-plant volatiles presented in the absence of other cue...

Pseudomonas syringae pv. tomato DC3000 is a model pathogen for studying the molecular basis of plant immunity and disease susceptibility in tomato and Arabidopsis. DC3000 uses a type III secretion system to inject effector proteins into the plant cell. Type III effectors are thought to promote bacterial virulence by suppressing plant defenses and enhancing access to nutrients trapped in the pla...

Verticillium wilts caused by soilborne fungal species of the Verticillium genus are economically important plant diseases that affect a wide range of host plants and are notoriously difficult to combat. Perception of pathogen(-induced) ligands by plant immune receptors is a key component of plant innate immunity. In tomato, race-specific resistance to Verticillium wilt is governed by the cell s...

The AvrPto protein from Pseudomonas syringae pv tomato is delivered into plant cells by the bacterial type III secretion system, where it either promotes host susceptibility or, in tomato plants expressing the Pto kinase, elicits disease resistance. Using two-dimensional gel electrophoresis, we obtained evidence that AvrPto is phosphorylated when expressed in plant leaves. In vitro phosphorylat...

powdery mildew is one of the most important disease concerns of tomato production in different regions of the world, which is caused by different species of erysiphales. the most important causal agents of which are leveillula taurica and oidium neolycopersici. in the present study tomato farms in qazvin province were surveyed and tomato leaves with powdery mildew symptoms were collected. after...

Pseudomonas syringae pv. tomato, the causal agent of bacterial speck of tomato, and the plant growth-promoting bacterium Azospirillum brasilense were inoculated onto tomato plants, either alone, as a mixed culture, or consecutively. The population dynamics in the rhizosphere and foliage, the development of bacterial speck disease, and their effects on plant growth were monitored. When inoculate...
