alpha,alpha-Trehalose induced a rapid blackening of the terminal 2.5-centimeter region of excised Cuscuta reflexa Roxb. vine. The incorporation of radioactivity from [(14)C]glucose into alkali-insoluble fraction of shoot tip was markedly inhibited by 12 hours of trehalose feeding to an excised vine. This inhibition was confined to the apical segment of the vine in which cell elongation occurred...
Yuen, G. Y., Alvarez, A. M., Benedict, A. A., and Trotter, K. J. 1987. Use of monoclonal antibodies'to monitor the dissemination of Xanthomonas campestris pv. campestris. Phytopathology 77:366-370. Monoclonal antibodies (MCA) were used to detect and differentiate on FS from 98% of samples (341 of 348) of lesions with definite black rot strains of Xanthomonas campestris pv. campestris isolated f...
Previous studies have indicated that some species of Cuscuta possess anticancer activity on various cell lines. Due to the lack of detailed researches on the cytotoxic effects of Cuscuta chinensis and Cuscuta epithymum, the aim of the present study was to evaluate cytotoxic effects of chloroform and hydroalcoholic extracts of these plants on the human breast carcinoma cell line (MDA-MB-468), hu...
Genomic DNA of 191 strains of the family Pseudomonadaceae, including 187 strains of the genus Xanthomonas, was cleaved by EcoRI endonuclease. After hybridization of Southern transfer blots with 2-acetylamino-fluorene-labelled Escherichia coli 16+23S rRNA probe, 27 different patterns were obtained. The strains are clearly distinguishable at the genus, species, and pathovar levels. The variabilit...
The fermentation product of herbs by lactic acid bacteria (FHL) was assayed for antifungal activities against Rosellinia necatrix, Helicobasidium mompa, Fusarium oxysporum, Pythium graminicola and Pyricularia oryzae. FHL completely inhibited the growth of R. necatrix, H. mompa, P. graminicola and P. oryzae, and reduced the growth of F. oxysporum by 35%. When the seeds of Medicago sativa L. (alf...
introduction dodder (cascuta campestris yuncker) is an annual parasitic plant from the convolvulaceae family (mishra et al., 2007). it wraps around many adjacent dicot and a few monocot plants, penetrates in their vascular tissue and exploits photosynthates, nutrients and water (lanini & kogan, 2005). consequently, the growth, vigor and production of the host plant will be severely reduced (nad...
17 اکوتیپ سس زراعی از نواحی مختلف ایران با استفاده از نشانگرهای issr و پروتئینی مورد ارزیابی قرار گرفتند.از ده آغازگر issr، در مجموع 361 باند نمره دهی شد که در بین آنها 347 باند چند شکل بودند. میانگین pic (محتوای اطلاعات چند شکلی ) بر پایه داده های issr و پروتئینی ، به ترتیب 66/0 و 4/0 محاسبه گردید . تجزیه خوشه ای و پلات های pca حاصل از ضریب تشابه دایس ، همخوانی بالایی داشتند. آنالیز واریانس مو...
Introduction: Epilepsy is the second most common nervous disorder after brain strok. In spite of present anticonvulsant drugs, researchers need to search for drugs with better efficacy and less side effects. Medicinal plants with various natural components so that different properties are suitable field for investigation. In this study, anticonvulsant effect of Lavandula vera DC. and Cuscuta ep...
The production of hesperetin glycosides was investigated using glycosylation with Xanthomonas campestris and cyclodextrin glucanotransferase (CGTase). X. campestris glucosylated hesperetin to its 3'-, 5-, and 7-O-glucosides, and CGTase converted hesperetin glucosides into the corresponding maltosides. The resulting 7-O-glucoside and 7-O-maltoside of hesperetin showed inhibitory effects on IgE a...
