Dimorphism or morphogenic conversion is exploited by several pathogenic fungi and is required for tissue invasion and/or survival in the host. We have identified a homolog of a master regulator of this morphological switch in the plant pathogenic fungus Fusarium oxysporum f. sp. lycopersici. This non-dimorphic fungus causes vascular wilt disease in tomato by penetrating the plant roots and colo...
Development of tomato varieties and hybrids with resistance to the pathogen Fusarium oxysporum f sp. Lycopersici is a priority in breeding vegetable crops. Evaluation selection initial material important effective for pathogen. To do this, along classical methods breeding, method molecular marking widely used. The purpose this study was screen existing collection tomatoes markers I-2/5, I2OH At...
A field experiment was conducted at ARS, Bhavanisagar, during summer 2021, to investigate the effect of multi-nutrient-loaded electrospun PVA nanofibre on green gram. The developed from polyvinyl alcohol (10%) infused with macro and micronutrients. coated seeds recorded higher plant height (44.97 cm); crop growth rate (1.5- 18.43 g m-2 d-1); leaf area index (0.56-1.84 m2m-2) duration (13.29-34....
The fungus Fusarium oxysporum f. sp. radicis-lycopersici causes foot and root rot of tomato plants, which can be controlled by the bacteria Pseudomonas fluorescens WCS365 and P. chlororaphis PCL1391. Induced systemic resistance is thought to be involved in biocontrol by P. fluorescens WCS365. The antifungal metabolite phenazine-1-carboxamide (PCN), as well as efficient root colonization, are es...
چکیده گیاه گوجه فرنگی همانند سایر گیاهان دارای مکانیسمهای متعددی در برابر حمله پاتوژنها می باشد که یکی از این مکانیسم ها تولید ترکیبات phytoanticipine می باشد از جمله ? - tomatine که بطور طبیعی در گیاه گوجه فرنگی و در تمام قسمتهای آن وجود داشته و خاصیت antimicrobial دارد. یکی از مهمترین بیماریهای گوجه فرنگی بیماری پژمردگی آوندی با عامل fusarium oxysporum f.sp. lycopersici می باشد که این پاتو...
Fusarium oxysporum is an ascomycetous fungus that is well-known as a soilborne plant pathogen. In addition, a large population of nonpathogenic F. oxysporum (NPF) inhabits various environmental niches, including the phytosphere. To obtain an insight into the origin of plant pathogenic F. oxysporum, we focused on the tomato (Solanum lycopersicum) and its pathogenic F. oxysporum f. sp. lycopersic...
In this study, bacterial strains were isolated from soils from 30 locations of Samcheok, Gangwon province. Of the isolated strains, seven showed potential plant growth promoting and antagonistic activities. Based on cultural and morphological characterization, and 16S rRNA gene sequencing, these strains were identified as Paenibacillus species. All seven strains produced ammonia, cellulase, hyd...
during the growing seasons of 2009 and 2010, same tomato fields throughout marvdasht were visited and 96 isolates of fusarium spp. were collected from root, crown and stem of diseased tomato plants. isolates were identified as based on morphological characteristics. they were divided into four species namely: fusarium solani, f. pseudoanthophilum, f. oxysporum and f. equiseti. these species,...
Ocimum gratissimum L. or clove basil, belongs to the Lamiaceae family, has various desirable uses and applications. Beyond its aromatic, seasoning, and medicinal applications, this plant also has antimicrobial activity. This study was aimed at assessing the antifungal activity, yield, and composition of the essential oil (EO) of O. gratissimum. The species was cultivated in garden beds with dys...
Plants and animals rely on immune receptors, known as nucleotide-binding domain and leucine-rich repeat (NLR)-containing proteins, to defend against invading pathogens and activate immune responses. How NLR receptors respond to pathogens is inadequately understood. We previously reported single-residue mutations that expand the response of the potato immune receptor R3a to AVR3a(EM), a stealthy...
