Native strains of Bradyrhizobium japonicum were tested for their effectiveness on nodulation, crop yield and nitrogen fixation in soybean (Glycine max). B. japonicum strains were isolated from soybean root nodules collected from different agro-climatic regions of Far Western Nepal, viz. Dipayal (607 m asl), Dadeldhura (1097 m asl), Silgadhi (1209 m asl) and Bajura (1524 m asl). The strains were...

Mechanisms inhibiting legume nodulation by low soil pH, although highly prevalent and economically significant, are poorly understood. We addressed this in soybean (Glycine max) using a combination of physiological and genetic approaches. Split-root and grafting studies using an autoregulation-of-nodulation-deficient mutant line, altered in the autoregulation-of-nodulation receptor kinase GmNAR...

this research was carried out at the research farm, faculty of agriculture, bu-ali sina university in growing season of 2011-2012. the aim of research was to evaluate the effect of foliar application of nano-iron chelate and bacterization of mesorhizobium bacteria on root nodulation, growth, grain yield and yield components of chickpea under rainfed conditions. a randomized complete block desig...

Improved seeds are increasingly being sown in agricultural practice. Such treatments play different roles depending on the substances used. They most often protect and sprouts from abiotic biotic stresses, but not only. Coating technology is one of methods seed improvement, requiring selection appropriate components. The purpose pot experiment was to test efficacy two coatings (C D) a commercia...

Legume plants form nitrogen-fixing nodules on their roots in symbiosis with soil bacteria rhizobia. The number of symbiotic is controlled by a host plant via systemic mechanism known as autoregulation nodulation (AON). key players AON are the CLE peptides which produced root response to rhizobia inoculation and transported xylem shoot. In shoot, recognized CLV1-like receptor kinase, results sub...

Rhizobium fredii USDA257 fails to nodulate the improved soybean [Glycine max (L.)Merr.] cultivar McCall in plastic growth pouches. Mutant 257DH4, which was derived from USDA257 by transposon mutagenesis, forms nitrogen fixing nodules under these conditions. If USDA257 is present in inocula containing the mutant, most infections are arrested prior to organization of the nodule meristem, and nodu...

The infectible cells of soybean roots appear to be located at any given time just above the zone of root elongation and just below the position of the smallest emergent root hairs. The location of infectible cells on the primary root at the time of inoculation was inferred from the position of subsequent nodule development, correcting for displacement of epidermal cells due to root elongation. ...

Four isolates each of Bacillus and Rhizobium sp were selected and characterized for their P-solubilization and auxin production. All the isolates produced auxin but with different degree of efficacy. The isolates of Rhizobium and Bacillus having maximum auxin production and P-solubilization were selected and further evaluated for improving growth, nodulation and yield of mungbean at two fertili...

Abstract Purpose Crops rely on microbes for critical services, but host benefits can be influenced by local makeup of microbiota and the host’s capacity to select optimal strains. We investigated that cowpeas receive from depending plant genotype, their domestication status, soil source. Methods performed a full factorial inoculation experiment. Twenty diverse cowpea genotypes, selected wild do...
