Forty-three Fusarium oxysporum strains and one Fusarium solani strain were analyzed for genetic diversity. These strains represent a wide range of geographic locations and were collected primarily from tomato (Lycopersicon esculentum) roots. Among all 43 F. oxysporum strains, 21 were not pathogenic to tomato, 20 were pathogenic, including 13 strains of Fusarium oxysporum lycopersici and seven s...
Few commercial genotypes of tomato are resistant to Fusarium wilt (Fusarium oxysporum f. sp. lycopersici [FOL]), especially race 3. We developed five intraspecific hybrids Solanum lycopersicum (FOX1 FOX5) and assessed them for agronomic traits resistance FOL races 1, 2, 3, a mixture these races. FOX1 FOX4 were all the but did not have desired traits. Next, as rootstocks cherry Sweet Heaven. The...
The I2 locus in tomato confers resistance to race 2 of the soil-borne fungus Fusarium oxysporum f sp lycopersici. The selective restriction fragment amplification (AFLP) positional cloning strategy was used to identify I2 in the tomato genome. A yeast artificial chromosome (YAC) clone covering approximately 750 kb encompassing the I2 locus was isolated, and the AFLP technique was used to derive...
Staniaszek M., Szczechura W., Marczewski W. (2014): Identification of a new molecular marker C2-25 linked to the Fusarium oxysporum f.sp. radicis-lycopersici resistance Frl gene in tomato. Czech J. Genet. Plant Breed., 50: 285–287. Fusarium oxysporum Schlecht. f.sp. radicis-lycopersici Jarvis & Schoemaker (FORL) is a saprophytic fungus, responsible for the fusarium crown and root rot disease in...
Peran jamur Fusarium non patogenik sangat penting dalam mengendalikan maupun mencegah serangan patogen oxysporum f. sp. lycopersici. Tujuan dari riset ini yaitu mengetahui keanekaragaman di lahan endemis dan supresif serta potensi antagonismnya terhadap layu fusarium. Penelitian dilakukan laboratorium Jurusan Hama Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya Balai Besar Karantin...
دستیابی به اطلاعات مولکولی و ژنتیکی توانسته است بسیاری از چالش‌های علوم زیستی را در جنبه‌های مختلف حل کند. روش‌های کاربردی بسیاری جهت استخراج DNA از بافت‌های جانوری و گیاهی و سایر موجودات زنده شناسایی و معرفی شده است.، در بسیاری مطالعات ژنتیکی در جوامع میکروبی، اغلب نیاز به استخراج مستقیم DNA از خاک است. در این تحقیق پس از مطالعه دقیق روش‌های مختلف پیشنهادی، سه روش (شیمیایی- آنزیمی)، (شیمیایی-...
Characterization of plant resistance genes is an important step in understanding plant defense mechanisms. Fusarium oxysporum f sp lycopersici is the causal agent of a vascular wilt disease in tomato. Genes conferring resistance to plant vascular diseases have yet to be described molecularly. Members of a new multigene family, complex I2C, were isolated by map-based cloning from the I2 F. o. ly...
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...
