Arabidopsis thaliana is a host to the powdery mildew Erysiphe cichoracearum and nonhost to Blumeria graminis f. sp hordei, the powdery mildew pathogenic on barley (Hordeum vulgare). Screening for Arabidopsis mutants deficient in resistance to barley powdery mildew identified PENETRATION3 (PEN3). pen3 plants permitted both increased invasion into epidermal cells and initiation of hyphae by B. g....
To identify components of the defense response that limit growth of a biotrophic fungal pathogen, we isolated Arabidopsis mutants with enhanced disease susceptibility to Erysiphe orontii. Our initial characterization focused on three mutants, eds14, eds15, and eds16. None of these is considerably more susceptible to a virulent strain of the bacterial pathogen Pseudomonas syringae pv. maculicola...
Powdery mildews and other obligate biotrophic pathogens are highly adapted to their hosts and often show limited host ranges. One facet of such host specialization is likely to be penetration of the host cell wall, a major barrier to infection. A mutation in the pmr5 gene rendered Arabidopsis resistant to the powdery mildew species Erysiphe cichoracearum and Erysiphe orontii, but not to the unr...
اثر بیکربنات پتاسیم در مدیریت بیماری سفیدک پودری جالیز، با هدف استفاده از مواد بی خطر و سازگار با محیط زیست روی میزبان خیار در قالب طرح بلوک های کامل تصادفی با هشت تیمار و چهار تکرار در شرایط گلخانه ای طی سالهای 1388 و 1389 بررسی گردید. تیمارهای آزمایشی شامل رژیم های مختلف سم پاشی با قارچ کش های کروزکسیم متیل (استروبی wg 50%) از گروه استروبیلورین، تتراکونازول (دومارک ec 10%) از گروه تریازول و ...
BACKGROUND Rhizomania is one of the most devastating diseases of sugar beet. It is caused by Beet necrotic yellow vein virus (BNYVV) transmitted by the obligate root-infecting parasite Polymyxa betae. Beta macrocarpa, a wild beet species widely used as a systemic host in the laboratory, can be rub-inoculated with BNYVV to avoid variation associated with the presence of the vector P. betae. To b...
This paper presents a study of the role of positive charge in the P(i) binding site of Escherichia coli ATP synthase, the enzyme responsible for ATP-driven proton extrusion and ATP synthesis by oxidative phosphorylation. Arginine residues are known to occur with high propensity in P(i) binding sites of proteins generally and in the P(i) binding site of the betaE catalytic site of ATP synthase s...
