A total o f 28 strains o f several species o f Rhizobium were screened for the presence and regulation of the enzyme alkaline phosphatase. In contrast to all other species o f Rhizobium, the activity of this enzyme was absent in R. trifolii. D ifferent levels o f alkaline phosphatase were observed in various species o f Rhizobium. Both, species as well as strain specific differences were found ...

The Experiment was conduct at Crop Research Farm, Department of Agronomy during Rabi season 2022 on Lentil crop. treatment consisted three level Biofertilizer Rhizobium, PSB and Rhizobium + Phosphorus (30, 40 50 kg/ha) control. experiment layout in Randomized Block Design (RBD) with 10 replicated thrice. soil the experimental area sandy loam pH (8.0), EC (0.56 dS/m), Organic Carbon (0.62%), ava...

Preferential rewarding of more beneficial partners may stabilize mutualisms against the invasion of less beneficial, that is cheater, genotypes. Recent evidence suggests that both partner choice and sanctioning may play roles in preventing the invasion of less-beneficial rhizobia in legume-rhizobium mutualisms. The importance of these mechanisms in natural communities, however, remains unclear....

Calliandra grandiflora has been used as a medicinal plant for thousands of years in Mexico. Rhizobial strains were obtained from root nodules of C. grandiflora collected from different geographical regions in Chiapas and characterized by BOX-PCR, amplified rDNA restriction analysis (ARDRA) and 16S rRNA gene sequence analysis. Most isolates corresponded to members of the genus Rhizobium and thos...

In this study dairy sludge was evaluated as an alternative cultivation medium for Rhizobium. Growth of bacterial strains at different concentrations of Dairy sludge was monitored. Maximum growth of all strains was observed at 60% Dairy sludge concentration. At 60% optical density (OD) values are 0.804 for Rhizobium trifolii (MTCC905), 0.825 for Rhizobium trifolii (MTCC906), and 0.793 for Rhizob...

In conformity with the nomenclature of the genus Rhizobium published by Young et al. (Int J Syst Evol Microbiol 51, 89-103, 2001), it is proposed that Agrobacterium larrymoorei be named as Rhizobium larrymoorei comb. nov.

Halo-tolerant, auxin producing bacteria could be used to induce salt tolerance in plants. A number of Rhizobium and auxin producing rhizobacterial strains were assessed for their ability to tolerate salt stress by conducting osmoadaptation assay. The selected strains were further screened for their ability to induce osmotic stress tolerance in mung bean seedlings under salt-stressed axenic cond...

We studied the production of xyloglucanase enzymes of leguminous roots in the presence of Rhizobium and arbuscularmycorrhizal (AM) fungi. The AM fungus Glomus mosseae and Sinorhizobium meliloti GR4 for alfalfa, Rhizobium leguminosarum bv. viceae Rlv 13 for pea, R. leguminosarum bv. trifolii 2152 for clover, R. tropici CIAT 899 for bean and Mesorrhizobium mediterraneum USDA 3392 for chickpea. Th...

Rhizobium sp. LMB-1, newly isolated from greenhouse soil, can effectively degrade phthalate. Here, we present a 5.2-Mb assembly of this Rhizobium sp. genome for the first time. It may provide abundant molecular information for the transformation of phthalates.
