ظهور تکنولوژی های جدید و پیشرفت دانش بشری در امر حفاظت از محیط زیست و نیز توجه خاص به آلاینده های خاک و خطر ناشی از مدیریت ناصحیح مواد شیمیایی بر سلامت بشر، به نگرش جدیدی در مدیریت بیماری های گیاهی منجر شده است. در این راستا کاربرد مواد آلی به عنوان کود با توجه به قیمت پایین و اثرات زیانبار محیطی کمتر آن در مقایسه با قارچ کش ها و ترکیبات تدخینی، نویددهنده مدیریت سالم تر تولیدات کشاورزی می باشد....
MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are short (19-25 nucleotides) non-coding RNA molecules that have large-scale regulatory effects on development and stress responses in plants. Verticillium wilt is a vascular disease in plants caused by the fungal pathogen Verticillium dahliae. The objective of this study is to investigate the transcriptional profile of miRNAs and other sma...
Verticillium wilt, a vascular disease in more than 200 dicotyledonous plants, is due to the ascomycete fungus Verticillium dahliae. As documented by video-microscopy, the soil bacterium Streptomyces lividans strongly reduces the germination of V. dahliae conidia, and the subsequent growth of hyphae. Quantification by the use of DNA-intercalating dyes and Calcofluor-staining revealed that during...
امروزه پژمردگی ورتیسیلیومی با عامل Verticillium dahliae از مشکلات متداول در باغهای زیتون شمال ایران میباشد. نماتد ریشه گرهی Meloidogyne javanica از نظر پراکنش یکی از گستردهترین نماتدهای باغات زیتون در ایران به شمار میآید. هدف از انجام این تحقیق بررسی تاثیر دو نوع بستر رویش بر تعامل دو بیمارگر مورد نظر میباشد. در اینآزمایش میکرواسکلروتهایVerticillium dahliae و لاروهای سن دوم Meliodogyne...
Verticillium nonalfalfae is a fungal plant pathogen that causes wilt disease by colonizing the vascular tissues of host plants. The disease induced by hop isolates of V. nonalfalfae manifests in two different forms, ranging from mild symptoms to complete plant dieback, caused by mild and lethal pathotypes, respectively. Pathogenicity variations between the causal strains have been attributed to...
Verticillium dahliae, a ubiquitous phytopathogenic fungus, forms resting structures, known as microsclerotia that play crucial roles in Verticillium wilt diseases. VdHog1, a mitogen-activated protein kinase (MAPK), controls microsclerotia formation, virulence, and stress response in V. dahliae. In this study, we present detailed evidence that the conserved upstream component of VdHog1, VdPbs2, ...
The plant defensin NaD1, from Nicotiana alata, has potent antifungal activity against a range of filamentous fungi including the two important cotton pathogens, Fusarium oxysporum f. sp. vasinfectum (Fov) and Verticillium dahliae. Transgenic cotton plants expressing NaD1 were produced and plants from three events were selected for further characterization. Homozygous plants were assessed in gre...
Arbuscular mycorrhizal fungi (AMF) play an important role in nutrient cycling processes and plant stress resistance. To evaluate the effect of Rhizophagus irregularis CD1 on plant growth promotion (PGP) and Verticillium wilt disease, the symbiotic efficiency of AMF (SEA) was first investigated over a range of 3% to 94% in 17 cotton varieties. The high-SEA subgroup had significant PGP effects in...
MicroRNAs (miRNAs) are a group of endogenous small non-coding RNAs that play important roles in plant growth, development, and stress response processes. Verticillium wilt is a vascular disease in plants mainly caused by Verticillium dahliae Kleb., the soil-borne fungal pathogen. However, the role of miRNAs in the regulation of Verticillium defense responses is mostly unknown. This study aimed ...
Verticillium dahliae Kleb. the causal agent of vascular wilt is an important pathogen of olive trees in growing areas of the world. Nine-month-old nursery olives including ‘Bladi’, ‘Conservalia’, ‘Kalamon’, ‘Koroneiki’, ‘Manzanilla’, ‘Mission’, ‘Marry’, ‘Picual’, ‘Rowghani’, ‘Sevillana’ and ‘Zard’ cultivars were root-dip inoculated with a defoliating (VCG1) isolate of V. dahliae obtained from d...
