in this study, the biological effects of sugar beet leaf saponins on spotted alfalfa aphid was evaluated using thin layer chromatography. after saponin extraction from the leaf, three saponin concentrations together with a diet lacking saponin (control) were fed to aphids in five replications. the aphids’ survival and fertility were evaluated and analysed. results not only showed fertility impa...

By using a differential proteomic approach, responses to drought stress in sunflower have been studied. Two sunflower genotypes, showing different levels of tolerance to drought have been utilized. Following TCA-acetone protein extraction, the 2-DE leaf protein profile of well watered and drought stressed plants have been compared. Coomassie staining of the gels allowed visualization of around ...

Twenty fungal isolates associated with leaf spots of nutsedge plants (Cyperus spp.) from north of Iran (Guilan, Mazandaran, Zanjan and Golestan Provinces) are examined. According to the results of the morphological studies of grown fungi on culture media, Curvularia clavata, Curvularia lunata var. aeria, Dactylaria higginsii, and Myrothecium brachysporum are new taxa for Iran mycoflora and repo...

Tomato crop is primarily infected by various common diseases like Bacterial Canker, bird's-eye fruit spots, Bacterial Spot, Chlorosis, Curly Top, Early Blight, Fusarium Wilt, Gray Leaf, Gray Mold Rot, Leaf Mold, Leaf Roll and Leaf Curl, Powdery mildew, Septoria Leaf Spot, Tobacco Mosaic Virus, Verticillium Wilt. The presented work describes a algorithm for different disease detection based on t...

Date palm cultivars differently tolerate salinity and drought stress. This study was carried out to study the response of date palm to severe salinity and drought based on leaf proteome analysis. Eighteen-month-old date palm plants were subjected to severe salt (48 g/L NaCl) and drought (82.5 g/L PEG or no irrigation) conditions for one month. Using a protein 2D electrophoresis method, 55 prote...
