The lichen Anaptychia fusca and several Stereocaulon species have been chemically investigat ed with regard to their content o f unknown ninhydrin-positive compounds. N ew aliphatic and alicyclic, amino components isolated from water extracts o f these lichen species have been charac terised as aminopentitol, aminohexitol and aminocyclitetrol. To our knowledge, this is the first time that com...
Carotenoids, Chlorella fusca, Chlorophylls, Iron Stress, Vanadate The pigment composition of Chlorella fusca has been investigated in the absence and in presence of vanadate and during iron stress. 1. Fe-deficiency generally decreases algal pigment content without change of the ratio chloro phyll a/b. 2. A twofold vanadate induced increase of the chlorophylls is accompanied by a similar enhanc...
Busseola fusca (Lepidoptera: Noctuidae) is an important pest of maize and sorghum in sub-Saharan Africa. One century after its first description by Fuller in 1901, inaccurate information based on earlier reports are still propagated on its distribution (e.g., absent from the lower altitudes in East Africa) and host plant range (e.g., feeding on a large range of wild grass species). This review ...
the aim of this study was measuring the amount of heavy metals (nickel, cobalt, cadmium, chromium and zinc) in different tissues of black fish (capoeta fusca). for this reason, in july 2010, 24 black fish was caught at the central part qanats of birjand. the results showed that between the whole length and the weight of fish and concentration of heavy metals in different observed tissues there ...
Project Number: 13C-3361-4795 TITLE: Epidemiology and control of apple powdery mildew Principal Investigator: G. G. Grove, Plant Pathology, WSU-IAREC, Prosser, WA Objectives • Develop a forecasting model to improve management of apple powdery mildew, caused by Podosphaera leucotricha. • Develop biorational disease and fungicide-resistance management programs • Lower disease pressure through cha...
Podosphaera (Sphaerotheca) euphorbiae on Euphorbia epithymoides (= E. polychroma, cushion spurge) is reported for the first time in North America. Neoerysiphe (Erysiphe) galeopsidis on Lamium amplexicaule (henbit), Blumeria (Erysiphe) graminis on Festuca idahoenis (Idaho fescue), Taphrina johansonii on Populus tremuloides (trembling aspen), and Taphrina occidentalis on Alnus rubra (red alder) a...
Fungi were isolated from soil samples corresponding to pesticide-contaminated soil (CS) and noncontaminated soil (NCS) in the Annaba vicinity (Algeria) and identified. The number of isolates obtained from CS and NCS were 263 and 288, respectively. The most frequent species (Aspergillus fumigatus, A. niger, A. terreus, Absidia corymbifera, and Rhizopus microsporus var microsporus) were not sensi...
In this study, ITS–rDNA region was used to identify some anamorphic powdery mildews in Guilan province. According to the results, Erysiphe species on Vicia faba and Sesbania punicea showed 100% similarity to each other, however, without ITS sequence of holotype of E. sesbaniae it is impossible to make conclusion whether Vicia faba powdery mildew fungus actually belongs to E. sesbaniae or E. tri...
بهمنظور مطالعه گونههای تیره erysiphaceae که به صورت غیرجنسی (آنامورف) روی میزبانهای مختلف وجود دارند، و اغلب با نام جنس آنامورفیک (شبه جنس) oidium معرفی میشوند، نمونههای متعددی از نقاط مختلف استان گیلان طی سالهای 1390-1383 جمعآوری شد. هدف از این مطالعه امکان شناخت گونههای موجود بر اساس خصوصیات آنامورف و فهم ارتباط آنها با گونههای تلئومورف بود. بر اساس نتایج بهدست آمده نمونههای مطالعه ...
bioaccumulation and depuration of copper in the kidney and liver of a freshwater fish, capoeta fusca
background: this study aims to investigate the patterns of bioaccumulation and depuration of copper in the selected kidney and liver of capoeta fusca. methods: the fish were collected between september and november 2010 from a qanat in birjand. they were exposed to two types treatments with copper (0.25 and 0.75 mg/l) for a period of 41 days. the fish under study were exposed to the above-menti...
