A ciprotloxacin resi stant mutant (Cf) of Rhizobium legulIlinossarulll bv phaseoli USDA 2695 which nodulates common bean plants (Phaseolus vulgaris L) was isolated after nitrous acid mutagenesis. Another m tant resistant to nalidi xic acid (NaIR) was isolated spontaneously. Both mutants showed thermotolerance as evident by their abi lity to grow at elevated (40°C) temperature, although the wi l...
BacA is an integral membrane protein, the mutation of which leads to increased resistance to the antimicrobial peptides bleomycin and Bac7(1-35) and a greater sensitivity to SDS and vancomycin in Rhizobium leguminosarum bv. viciae, R. leguminosarum bv. phaseoli, and Rhizobium etli. The growth of Rhizobium strains on dicarboxylates as a sole carbon source was impaired in bacA mutants but was ove...
abstract the present study deals with a comparison between reactive and pre-emptive focus-on-form in terms of application and efficiency. it was conducted in an intermediate english class in shahroud. 15 male learners participated in this research and their age ranged from 18 to 25. a course book, new interchange 3, and a complementary book were used. every session the learners gave lectures o...
the objective of this research work was to study the effect of rhizobium leguminosarum pre-induced with genistein (g) and methyl jasmonate (mj) on nodulation, nitrogen fixation and early growth of the common bean (phaseolus vulgaris l.). four day-old seed-lings were transferred to pots, containing sterilized sand and turface (2:1 v:v) mixture and, receiving hoagland’s nutrient solution, without...
in order to study the biological fixation efficiency of different strains of symbiosis bacteria in three varieties of common bean (phaseolus vulgaris l.) a factorial experiment based on randomized complete block design was conducted in zanjan province during 2006 and 2007. in this investigation three strains of rizobium including: rb117 (extracted from the zanjan soils), rb123 (extracted from t...
چکیدهبه منظور بررسی تأثیر تلقیح قارچ F. mosseae و باکتری‌های P. putida و R. leguminosarum (biovar phaseoli) بر تغذیه و عملکرد لوبیا، یک آزمایش گلخانه‌ای به صورت فاکتوریل در قالب طرح کاملا تصادفی با 3 تیمار شامل الف: ریزموجود (بدون تلقیح، باکتری P. putida ، قارچ F. mosseae و کاربرد همزمان باکتری و قارچ)، ب: سولفات روی (صفر و 10 میلی‌گرم بر کیلوگرم خاک) و ج: نیتروژن (تلقیح با باکتری R. leguminosa...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Thirty-one strains of two new genomic species (genomic species 1 and 2) of rhizobia isolated from root nodules of Phaseolus vulgaris and originating from various locations in France were compared with reference strains of rhizobia by performing a numerical analysis of 64 phenotypic features. Each genomic species formed a distinct phenon and was separated from the other rhizobial species. A comp...
Many bacterial species exhibit strong linkage disequilibrium of their chromosomal genes, which apparently indicates restricted recombination between alleles at different loci. The extent to which restricted recombination reflects limited migration between geographically isolated populations versus infrequent mixis of genotypes within populations is more difficult to determine. We examined the g...
