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...

ABSTRACT In the Mediterranean Basin, Fusarium oxysporum f. sp. ciceris and the root-knot nematode Meloidogyne artiellia coinfect chickpea. The influence of root infection (after inoculation with 20 nematode eggs and second-stage juveniles per gram of soil) by two M. artiellia populations, from Italy and Syria, on the reaction of chickpea lines and cultivars with partial resistance to Fusarium w...

ABSTRACT Fusarium oxysporum f. sp. ciceris and the root-lesion nematode Pratylenchus thornei coinfect chickpeas in southern Spain. The influence of root infection by P. thornei on the reaction of Fusarium wilt-susceptible (CPS 1 and PV 61) and wilt-resistant (UC 27) chickpea cultivars to F. oxysporum f. sp. ciceris race 5 was investigated under controlled and field conditions. Severity of Fusar...

OBJECTIVES Antifungal treatment of uncommon filamentous fungal infections is problematic. This study determined the in vitro susceptibility of miltefosine, as a single agent and in combination with posaconazole or voriconazole, against these pathogens. METHODS Susceptibility to miltefosine of 34 uncommon filamentous fungi was tested using CLSI broth microdilution M38-A2 methodology. Twenty is...

fusarium wilt of chickpea, caused by f. oxysporum f. sp. ciceris, is one of the most important diseases of this plant in iran. in order to control this disease, fluorescent pseudomonads were isolated from the rhizosphere of chickpea plants in khorasan province by using king,s b medium (kb). antifungal activity of 80 bacterial strains against f. oxysporum f. sp. ciceris was evaluated on kb and p...

The tomato vascular wilt pathogen Fusarium oxysporum f. sp. lycopersici produces an array of pectinolytic enzymes that may contribute to penetration and colonization of the host plant. Here we report the isolation of pg5, encoding a novel extracellular endopolygalacturonase (endoPG) that is highly conserved among different formae speciales of F. oxysporum. The putative mature pg5 product has a ...

Background: Chickpea wilt complex caused by several soil-borne pathogens is the major yield-reducing malady worldwide. Biological control one of best, low-cost and ecologically sustainable method for managing plant diseases pathogens. Methods: In this present investigation Panchagavya Trichoderma spp. were evaluated following poisoned food technique dual culture against causing i.e. Fusarium ox...

the genus fusarium is a species rich genus. different media are required to study themorphological characters and classify different species, a time consuming technique. in this study pecticzymograms were used to identify species and form species of fusarium isolates. fusarium isolates (318) wereobtained from different areas and hosts in isfahan province, iran. isolates were identified to speci...

Monoconidial cultures of 15 isolates of Trichoderma harzianum were characterized on the basis of 82 morphological, physiological, and biochemical features and 99 isoenzyme bands from seven enzyme systems. The results were subjected to numerical analysis which revealed four distinct groups. Representative sequences of the internal transcribed spacer 1 (ITS 1)-ITS 2 region in the ribosomal DNA ge...
