Rabbit antibody to cutinase-I, isolated from Fusarium solani f. pisi, was conjugated to ferritin. With this ferritin-conjugated antibody it was shown that germinating spores of this fungus excreted cutinase during the penetration of the host pisum sativum. This result constitutes the most specific and strongest evidence for an enzymic penetration of a plant cuticle by a pathogen during infection.
Calorie values for a wide biological selection of nematodes, determined with a microbomb calorimeter, ranged from 3.86 to 6.85 Kcal/g. The mean of 5.095 Kcal from 16 species was lower than means recorded in three previous studies of other invertebrate groups. The nematode values were skewed to the lowest limit. Larvae of Ditylenchus dipsaci showed lower calorie values after storage, and the cal...
Application of biochar, a pyrolyzed biomass from organic sources, to agricultural soils is considered a promising strategy to sustain soil fertility leading to increased plant productivity. It is also known that applications of biochar to soilless potting substrates and to soil increases resistance of plants against diseases, but also bear the potential to have inconsistent and contradictory re...
The soil-borne fungus Rhizoctonia solani causes damping-off on sugar beet seedlings. Growers rely fungicides to protect in fields affected by R. solani. Quinone outside inhibitor (QoI) fungicides, such as azoxystrobin, have been applied in-furrow and foliar sprays manage solani, but repeated use of QoI pose risks fungicide resistance. Penthiopyrad is a novel with the succinate dehydrogenase (SD...
به منظور شناسایی نماتدهای انگل گیاهی مزارع پنبه در استان خراسان¬جنوبی، در سال 1392، تعداد 56 نمونه خاک از مناطق مختلف استان جمع¬آوری گردید. شستشوی خاک و استخراج نماتدها با استفاده از روش تغییریافته تلفیق الک و سانتریفیوژ جن¬کینز (1969) و سینی وایت هد (1965) و تثبیت و انتقال آن¬ها به گلیسرین طبق روش دگریس (1969) انجام گرفت. سپس از نماتدهای استخراج شده به تفکیک جنس، اسلایدهای میکروسکوپی تهیه و با...
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...
A total of 33 isolates of Fusarium sp. were isolated from soil samples collected from a mangrove forest in an area in Kampung Pantai Acheh, Balik Pulau, Pulau Pinang, Malaysia. The isolates were isolated using soil dilution, direct isolation and debris isolation techniques. The debris isolation technique yielded the most isolates, with a total of 22 Fusarium isolates. Based on identification us...
