Abstract Ascochyta blight (caused by Didymella rabiei ) is one of the most important diseases affecting chickpea production and productivity. The distribution, incidence severity disease, association agronomic practices environmental factors on intensity disease mainly remained undermined. Chickpea field surveys were conducted in two main growing regions central Ethiopia during 2020 2021 croppi...

The response of pea (Pisum sativum) genotypes to ascochyta blight disease and the effect of disease severity on yield components were evaluated in a 4-year trial under field conditions. Peas were inoculated with Ascochyta pinodes, the anamorph of Mycosphaerella pinodes, or with Phoma pinodella separately and with a mixture of both species. Mean infection ratings of all inoculation treatments we...

Ascochyta blight, an infection caused by a complex of Ascochyta pinodes, Ascochyta pinodella, Ascochyta pisi, and/or Phoma koolunga, is a destructive disease in many field peas (Pisum sativum L.)-growing regions, and it causes significant losses in grain yield. To understand the composition of fungi associated with this disease in Zhejiang Province, China, a total of 65 single-pycnidiospore fun...

بیماری سوختگی اسکوکیتایی در اثر قارچ Ascochyta rabiei (Pass.) Lab.، مهم‌ترین بیماری نخود معمولی در دنیا و ایران است. آگاهی از نژادهای عامل بیماری در هر منطقه برای دستیابی به ارقام مقاوم ضروری است. در این تحقیق نژادهای فیزیولوژیک 28جدایه A. rabiei که در سال‌های 1392و1393 از پنج ناحیه استان کرمانشاه جمع‌آوری و خالص‌سازی شده بودند، با استفاده از هفت رقم افتراقی نخود بررسی و در نهایت در شش نژاد فیز...

In response to the exogenous application of elicitors and attempted invasion by pathogens, plants exhibit a wide range of defense reactions. To understand the defense mechanisms at the level of gene activation and deactivation, differential screenings were performed to isolate cDNA clones which are differentially expressed in pathogen-inoculated resistant chickpea plants and elicitor-treated ce...

The anamorphic pycnidial fungus Ascochyta pisi is one member of a species complex that causes Ascochyta blight of pea, a potentially devastating disease. The teleomorphic state of this fungus was induced under laboratory conditions. Using morphological and molecular characters, we placed the teleomorph within the genus Didymella as D. pisi and describe a heterothallic mating system using a PCR-...

Plant pathogenic microorganisms produce a variety of enzymes capable of degrading different polysaccharides of the plant cell walls. Pathogens use these enzymes to penetrate and colonize host cells. Polygalacturonases are thought to be the first cell wall-degrading enzymes secreted by pathogens when they grow on plant cell walls. Oligogalacturonic acids with the polymerization degrees of 10 to ...
