This is the first study reporting the evaluation of transgenic lines of tomato harboring rice chitinase (RCG3) gene for resistance to two important fungal pathogens Fusarium oxysporum f. sp. lycopersici (Fol) causing fusarium wilt and Alternaria solani causing early blight (EB). In this study, three transgenic lines TL1, TL2 and TL3 of tomato Solanum lycopersicum Mill. cv. Riogrande genetically...

Kitagawa, T., Sakamoto, Y., Furumi, K., and Ogura, H. 1989. Novel enzyme immunoassays for specific detection of Fusarium oxysporum f. sp. cucumerinum and for general detection of various Fusarium species. Phytopathology 79:162-165. Competitive types of two novel enzyme-linked immunosorbent assays including nine other strains of Fusarium, showed little cross-reactivity. (ELISA) for Fusarium spec...

abstract this study was carried out of identify the tomatinase extracellular enzyme in fusarium oxysporum f.sp. lycopersici race1 the casual agent of wilting in tomato. 20 isolates of fusarium oxysporum were recovered from infected roots,crown and stems of tomato plants collected from fields in major tomato producing areas in northern and razavi khorasan province during 2009-2010 . pathogenicit...

MicroRNAs (miRNAs) are a specialized group of small RNAs (sRNAs) that regulate gene expression in plants at both transcriptional and post-transcriptional levels. Numerous families miRNA target genes involved regulating plant immunity. In this study, we studied the role miRNAs defensive response against fungal pathogen, Fusarium oxysporum f. sp. lycopersici, which causes wilt disease tomatoes. F...

Phytohormones such as salicylic acid (SA), ethylene (ET) and jasmonic acid (JA) play key roles in plant defense following pathogen attack. Involvement of these hormones in plant susceptibility following Fusarium oxysporum (Fo) infection has mostly been studied in Arabidopsis thaliana. However, Fo causes vascular wilt disease in a broad range of crops, including tomato (Solanum lycopersicum). Su...

Abstract The tomato ( Solanum lycopersicum L.) is one of the most important vegetables grown globally. However, production tomatoes restricted by Fusarium oxysporum f. sp. lycopersici (Fol). This study aims to investigate ability Fol-resistant genotypes be a rootstock for susceptible cultivar. In this study, cultivar was grafted on rootstocks same species (intraspecific), and grafting compatibi...

XSP10 is an abundant 10 kDa protein found in the xylem sap of tomato. The protein displays structural similarity to plant lipid transfer proteins (LTPs). LTPs are involved in various physiological processes, including disease resistance, and some are able to bind and transfer diverse lipid molecules. XSP10 abundance in xylem sap declines upon infection with Fusarium oxysporum f. sp. lycopersici...

Greenhouse tomato growers in the United States have few products available for chemical control of plant pathogens. Biological control of soilborne plant pathogens by antagonistic microorganisms is a potential alternative to the use of chemical pesticides during greenhouse production. Biological control experiments were conducted to test the effects of commercial and noncommercial strains of Tr...

Wilt is an important disease of tomato crop causing significant reduction in yield. In present study, the pathogenic fungus was isolated from infected plant and identified based on morphological and cultural characters as Fusarium oxysporum f.sp.lycopersici whose pathogenicity was confirmed by Koch’s postulate on tomato seedling. In vitro evaluation of extracts of 20 plant species was done by p...
