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....
فلور قارچهای راسته های زنگ ها (uredinales) ، سیاهک ها (ustilaginales) و سفیدک های پودری(erysiphales) درمنطقه حفاظت شده جاجرود در شرق استان تهران که در بردارنده دو پارک ملی سرخه حصار و خجیر می باشد بررسی گردید . بر این اساس 26 گونه از راسته زنگ ها متعلق به جنس های melampsora, uromyces, puccinia, phragmidium ، 14 گونه از رسته سفیدک های پودری متعلق به جنس blumeria, podosphaera, leveillula, erysiph...
The alkaloid fuyuziphine was isolated from the whole plant of Fumaria indica. It had inhibitive effect against spore germination of some plant pathogenic fungi (Collectotrichum sp., C. gloeosporioides, C. falcatum, Curvularia maculans, C. lunata, Erysiphe cichoracearum, Helminthosporium pennisetti, Oidium erysiphoides, Ustilago cynodontis, Alternaria chieranthi, A. melongenae, A. brassicicola a...
• The strength and consistency of genotypic differences in disease resistance determine the potential for resistance evolution in host populations that rely on vegetative reproduction. Here we surveyed infection intensity of host genotypes across space and time to estimate genotypic and environmental effects on quantitative disease resistance. • Cloned fragments of 12 Euthamia graminifolia geno...
the compatibility studies of pseudomonas fluorescens (pf1) with azoxystrobin at differ-ent concentrations viz., 100, 150, 200, 250 and 300 ppm revealed that it was compatible with all the concentrations of azoxystrobin tested and the growth of the bacterium was unaffected even at the maximum concentration of 300 ppm. the field experiment revealed a foliar application of pf1 (2.5 kg ha-1) and az...
