abstract tomato spotted wilt virus (tswv) was detected in tomato leaf and fruit samples collected from viiramin reyion in tehran province using indicator test plants including petunia hybrida, nicatiana glutinosa, n. tabacum cv. snmsun nn, n. clevelandit and n. benthamiana and seroloyical tests. small browinsh local necrotic lesions appeared on p. hybrida leaves 2-4 days post-inoculation. syste...

Tomato plants often grow in saline environments in Mediterranean countries where salt accumulation in the soil is a major abiotic stress that limits its productivity. However, silicon (Si) supplementation has been reported to improve tolerance against several forms of abiotic stress. The primary aim of our study was to investigate, using comparative physiological and proteomic approaches, salin...

Tomato mottle mosaic virus (ToMMV) is an emerging seed-transmissible tobamovirus that infects tomato and pepper. Since the first report in 2013 Mexico, ToMMV has spread worldwide, posing a serious threat to production of both crops. To prevent this virus, early accurate detection infection required. In study, we developed method for based on reverse-transcription loop-mediated isothermal amplif...

Evaluation of crop N status will assist optimal N management of intensive vegetable production. Simple procedures for monitoring crop N status such as petiole sap [NO 3--N], leaf N content and soil solution [NO 3-] were evaluated with indeterminate tomato and muskmelon. Their sensitivity to assess crop N status throughout each crop was evaluated using linear regression analysis against nitrogen...

Plant constituents such as carotenoids and flavonoids are involved in the light-protecting system in plants and contribute to the prevention of UV damage in humans. As micronutrients they are ingested with the diet and are distributed into light-exposed tissues where they provide systemic photoprotection. beta-Carotene is an endogenous photoprotector, and its efficacy to prevent UV-induced eryt...

This study investigated the sensitivity of 92 isolates Passalora fulva from tomato plants in Wakayama Prefecture to thiophanate-methyl, penthiopyrad, boscalid, azoxystrobin, and triflumizole using agar dilution methods. All exhibited reduced more than two fungicides. Bioassays seedlings showed that mancozeb WP (wettable powder), TPN WP, iminoctadin-albesilate were effective against strains resi...

The major challenge for the tomato farmers is getting a fair price at the market price given that there are many actors involved in the tomato value chain. Given this situation, this project's goal was to improve communication pathways in dissemination of agricultural market information in tomato value chains in Iringa and Dodoma Regions in Tanzania. The specific objectives were to: identify an...

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...
