Trichoderma asperellum has been fronted as a biocontrol agent of root-knot nematodes on tomato and French beans in Kenya. Research on the effect of T. asperellum on growth of Rhizobium species is lacking yet the two interact within the rhizosphere particularly when T. asperellum is applied as a biocontrol agent. Legume roots and Rhizobium species have symbiotic relationship resulting in biologi...

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...

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 ...

Various strategic efforts to increase food production continue be made in an effort achieve self-sufficiency and security. Soybean is a national commodity support government programs with the aim of achieving self-sufficiency. The purpose this study was determine effect combination phosphate fertilizer rhizobium biofertilizer on growth soybean (Glycine max L) Grobogan variety. research conducte...

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 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.
