this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria(pgpr) on yield and yield components of chickpea (cicer arientinum l.) arman cultivar. this research was conducted as split plot based on randomized complete block design at zanjan university researchal farm. irrigation levels(optimum irrigation during season growth and no irrigat...

Crown gall, caused by Agrobacterium tumefaciens (syn. Rhizobium radiobacter), is characterized gall formation on crowns, stems or roots many plant species. We describe the occurrence of this disease for first time cannabis (Cannabis sativa L. marijuana) plants in two licenced production facilities British Columbia. Galls were observed and several genotypes, including ‘White Rhino’, ‘Pink Kush’ ...

abstract arsenic (as) contamination of soils is a global problem. legumes are often used in remediation of contaminated sites because of their capacity to fix nitrogen. in the present study, the effects of inoculation of bean (by rhizobium leguminosarum bv. phaseoli) on plant uptake and tolerance to arsenic were investigated. an experiment with a factorial arrangement, two levels of inoculation...

Growth and survival of two rhizobial strains, Rhizobium leguminosarum bv. trifolii, and Mesorhizobium ciceri, were used to evaluate residues from the cork industry as potential carriers for production of rhizobial inoculants. A peat-based carrier was used as a control. 41 days after inoculation, the number of viable bacteria was high, about 109 bacteria g-1 for all carriers. Rhizobial survival ...

Background: Indigenous rhizobial populations may be unable to achieve successful symbiosis in the field due rare population and unfavourable soil environment. Introduced plant growth promoting rhizobacteria (PGPR) are frequently linked faster growth, development, yield of with synergetic effect on indigenous Rhizobium bacteria. Furthermore, co-inoculating legumes both PGPR is proven more effect...

Rhizobium is a Gram-negative bacterium, which dissolves minerals, produces growth hormones, promotes root growth, and protects plants from different soil-borne pathogens. In the present study, roots, stalks, fresh weight of maize (Zea mays L.) were significantly increased after soaking in Bradyrhizobium japonicum compared with control. Subsequently, transcriptome sequencing results whole plant ...

salinity is one of the major problems in the world's vast areas of land are also faced with this problem. endophytes are microorganisms that use of the soil microorganisms, the reduction of environmental stresses such as salinity, has become a global solution. therefore, to investigate the effects of inoculation of fungal endophytes piriformospora indica and bacteria symbiosis hay azospiri...

Paclitaxel (Taxol®) is a potent anticancer agent, but the widespread pharmaceutical use of paclitaxel hampered by its limited availability due to low accumulation levels in native yew (Taxus spp.) plants. Currently, hairy root culture an emerging biotechnological tool that presents several advantages such as reduced costs and higher specialized metabolite production, therefore, application prod...

Enrichment of staple food with zinc (Zn) along solubilizing bacteria is a sustainable and practical approach to overcome Zn malnutrition in human beings by improving plant nutrition, nutrient use efficiency, productivity. Common bean (Phaseolus vulgaris L.) one global population has prospective role agronomic biofortification. In this context, we evaluated the effect diazotrophic bacterial co-i...
