A novel strategy for combating pathogens is through the ongoing development and use of anti-quorum sensing (QS) treatments such as therapeutic bacteria or their anti-QS substances. Relatively little is known about the bacteria that inhabit the open ocean and of their potential anti-pathogenic attributes; thus, in an initiative to identify these types of therapeutic bacteria, planktonic microbes...

Eight coals used as carriers in legume inoculants promoted the survival of Rhizobium phaseoli on pinto bean seeds. Although peat was more protective, most coal-based inoculants provided >10 viable rhizobia per seed after 4 weeks.

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...

to study the effects of different levels of seed ageing and bacteria inoculation on yield of common bean at field conditions, an experiment was carried out as factorial arranged in rcbd design with three replications at research farm of university of tehran (karaj-iran) in 2012. treatments consisted of four levels of seed ageing (0 (control), 3, 6 and 9 days at 41°c and 90-100% relative humidit...

Air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. SO2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. Symbiosis of Rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...

The structure of rhizobial communities nodulating native shrubby legumes in open eucalypt forest of southeastern Australia was investigated by a molecular approach. Twenty-one genomic species were characterized by small-subunit ribosomal DNA PCR-restriction fragment length polymorphism and phylogenetic analyses, among 745 rhizobial strains isolated from nodules sampled on 32 different legume ho...

This work centres on the genomic comparisons of two closely-related nitrogen-fixing symbiotic bacteria, Rhizobium leguminosarum biovar viciae 3841 and Rhizobium etli CFN42. These strains maintain a stable genomic core that is also common to other rhizobia species plus a very variable and significant accessory component. The chromosomes are highly syntenic, whereas plasmids are related by fewer ...

This study was conducted to investigate the effect of Rhizobium inoculation and the supply of Mo and lime on the uptake of macroelements in P. vulgaris. To achieve this aim, experiments were conducted at the glasshouse of the Cape Peninsula University of Technology, Cape Town (i.e. from August 2008 to January 2009) and field experiment at the Agricultural Research Council (ARC) Nietvoorbij site...

Rhizobia are a group of bacteria that form nodules on the roots of legume host plants. The sequenced genomes of the rhizobia are characterized by the presence of many putative insertion sequences (IS) elements. However, it is unknown whether these IS elements are functional and it is therefore relevant to assess their transposition activity. In this work, several functional insertion sequences ...
