Rhizobium leguminosarum bv. trifolii forms nitrogen-fixing root nodules on the pasture legume Trifolium repens, and T. repens seed is often coated with a compatible R. leguminosarum bv. trifolii strain prior to sowing. However, significant losses in bacterial viability occur during the seed-coating process and during storage of the coated seeds, most likely due to desiccation stress. The disacc...
Rhizobium leguminosarum bv. trifolii is capable of establishing a symbiotic relationship with plants from the genus Trifolium. Previously, a regulatory protein encoded by rosR was identified and characterized in this bacterium. RosR possesses a Cys2-His2-type zinc finger motif and belongs to Ros/MucR family of rhizobial transcriptional regulators. Transcriptome profiling of the rosR mutant reve...
Medicago truncatula was used to characterize resistance to anthracnose and powdery mildew caused by Colletotrichum trifolii and Erysiphe pisi, respectively. Two isolates of E. pisi (Ep-p from pea and Ep-a from alfalfa) and two races of C. trifolii (races 1 and 2) were used in this study. The A17 genotype was resistant and displayed a hypersensitive response after inoculation with either pathoge...
در این تحقیق اطلاعاتی در زمینهی پراکنش و رابطهی بین شتههای یونجه و پارازیتوییدهای آنها در مناطق مختلف یازده استان ایران همراه با کلید شناسایی ارایه میگردد. مهمترین شتههای یونجه عبارت بودند از Therioaphis trifolii maculata (Buckton) و Acyrthosiphon pisum (Harris) و سپس Aphis craccivora Koch و Acyrthosiphon kondoi Shinji. الگوی پراکنش این شتهها در مناطق مختلف متفاوت بود. T. trifolii maculat...
The symbiotic nitrogen-fixing bacterium Rhizobium leguminosarum bv. trifolii 24.2 secretes large amounts of acidic exopolysaccharide (EPS), which plays a crucial role in establishment of effective symbiosis with clover. The biosynthesis of this heteropolymer is conducted by a multi-enzymatic complex located in the bacterial inner membrane. PssA protein, responsible for the addition of glucose-1...
To differentiate among the roles of the three nodD genes of Rhizobium meliloti 1021, we studied the activation of a nodC-lacZ fusion by each of the three nodD genes in response to root exudates from several R. meliloti host plants and in response to the flavone luteolin. We found (i) that the nodD1 and nodD2 products (NodD1 and NodD2) responded differently to root exudates from a variety of hos...
مگس مینوز جالیز liriomyza trifolii (burgess)از آفات کلیدی و خسارتزا در کشت های گلخانهای خیار در بسیاری از نقاط کشور محسوب میگردد. این تحقیق بمنظور ارزیابی کارایی ترکیبات جدید حشره کش شامل آبامکتین (ورتیمک®ec 1.8% ) به میزان 600 میلی لیتر در هکتار، استامیپراید (موسپیلان®sp 20% ) به نسبت 750 گرم در هکتار و سیرومازین (تریگارد®wp 75% ) در دو میزان 100 و 200 گرم در هکتار در سال اول و در مقادیر ...
