In a previous study, we demonstrated that transgenic Lotus plants producing opines (which are small amino acid and sugar conjugates) specifically favor growth of opine-degrading rhizobacteria. The opine-induced bias was repeated and demonstrated with another soil type and another plant species (Solanum nigrum). This phenomenon is therefore independent of both soil type and plant species.

the occurrence of antibiotic-resistant pathogenic bacteria is becoming a serious problem. the rise of multiresistance strains has forced the pharmaceutical industry to come up with new generation of more effective and potent antibiotics, therefore creating development of antivirulence compounds. due to extensive usage of cell-to-cell bacterial communication (qs) systems to monitor the productio...

effects of various fertilizers such as farmyard manure (fm), urea, and plant growth promoting rhizobacteria (pgpr, including the genera azotobacter and azospirillium) were checked on yield, fatty acids, protein, and oil contents of sunflower. a two-year field experiment was conducted in a semi-arid region in iran in 2007 and 2008. the experiment was a split plot in a randomized complete block d...

The role of plant growth-promoting rhizobacteria (PGPR) in adaptation of plants in extreme environments is not yet completely understood. For this study native bacteria were isolated from rhizospeheric arid soils and evaluated for both growth-promoting abilities and antagonistic potential against phytopathogenic fungi and nematodes. The phylogentic affiliation of these representative isolates w...

In the present scenario, demand for food and nutrient has increased due to population growth. Ascribable industrialization urbanization, a very small area of productivity land is available maintenance life process. Agricultural growth depends upon microbial in soil over last few years. plant promoting rhizobacteria turned out be most efficient tool sustainable agriculture. PGPR, exert its effec...

Numerous species of soil bacteria which flourish in the rhizosphere of plants, but which may grow in, on, or around plant tissues, stimulate plant growth by a plethora of mechanisms. These bacteria are collectively known as PGPR (plant growth promoting rhizobacteria).Of the microorganisms that parasitize on nematodes and reduce nematode populations by antagonistic behaviour, bacteria hold an im...

The rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (PGPR). In this study, the isolation andidentification of rhizobacteria from orange (Citrus sinensis) orchards using 16S rRNA gene, as well asbiological and biochemical assays is reported. Analysis of 16S rRNA gene was confirmed bybiological and ...

Signaling among rhizobacteria and other soil microorganisms is an important mechanism to ensure a successful symbiotic relationship with their phytobionts. Quorum-sensing involves signaling molecules that provide essential networks for communication in the rhizosphere. These relay inter-and-intra-species information coordinates controls behavior mixed communities, expression of these changes re...
