The Root nodules of Cajanus Cajan plant produced high amount of (35.56 ug/gm) of Indole acetic acid from Hg plants as compared to the N plant. The IAA was measured maximum from Rhizobium spp. of C.cajan plant at 24h, when the bacteria reached the stationary phase of growth. Mannitol & KNO3 preferred to be a good carbon and nitrogen source for IAA production in all N, Ng, H & Hg Rhizobium strain...
Despite the importance of mutualism as a key ecological process, its persistence in nature is difficult to explain since the existence of exploitative, "cheating" partners that could erode the interaction is common. By analogy with the proposed policing strategy stabilizing intraspecific cooperation, host sanctions against non-N(2) fixing, cheating symbionts have been proposed as a force stabil...
Curing of symbiotic plasmid of Mesorhizobium huakuii subsp. rengei isolated from Astragalus sinicus.
Astragalus sinicus (Chinese Milk vetch), a green manure leguminous plant, harbors Mesorhizobium huakuii subsp. rengei strain B3 in the root nodules. The visualization of symbiotic plasmid of strain B3 showed the presence of one sym plasmid of about 425 kbp. Curing of sym plasmid by temperature and acrydine orange was studied. Growing rhizobial cells at high temperature (37 degrees C) or treatin...
Soybean inoculation with effective rhizobial strains makes unnecessary the use of N-fertilizers in the tropics. A frequently reported problem is the failure of the inoculant strains to overcome the competition imposed by indigenous rhizobial populations. The screening of indigenous rhizobia, already adapted to local conditions, searching for highly effective strains for use as inoculants repres...
Globins (Glbs) are proteins widely distributed in organisms. Three evolutionary families have been identified in Glbs: the M, S and T Glb families. The M Glbs include flavohemoglobins (fHbs) and single-domain Glbs (SDgbs); the S Glbs include globin-coupled sensors (GCSs), protoglobins and sensor single domain globins, and the T Glbs include truncated Glbs (tHbs). Structurally, the M and S Glbs ...
Indigenous rhizobia in soil present a competition barrier to the establishment of inoculant strains, possibly leading to inoculation failure. In this study, we used the natural diversity of rhizobial species and numbers in our fields to define, in quantitative terms, the relationship between indigenous rhizobial populations and inoculation response. Eight standardized inoculation trials were co...
Symbiotic nitrogen fixation provides most of the required for soybean growth. Rhizobial nodulation outer proteins (Nops) have been reported to influence host specificity during symbiosis establishment. However, that interact with Nops remain unknown. In this study, we generated Sinorhizobium fredii HH103 mutants (HH103ΩNopL, HH103ΩNopT, and HH103ΩNopLΩNopT) analysed nodule number (NN) dry weigh...
