Streptomyces sp. strain TOR3209, isolated from tomato rhizosphere, can regulate the rhizosphere microecology of a variety of crops. Strain TOR3209 could improve plant systemic resistance and promote plant growth. Here, the genome sequence of strain TOR3209 is reported, providing the molecular biological basis of the regulation mechanism of rhizosphere microecology.

Pseudomonas fluorescens pc78 is an effective biocontrol agent for soil-borne fungal diseases. We previously constructed a P43-gfp tagged biocontrol bacteria P. fluorescens pc78-48 to investigate bacterial traits in natural ecosystem and the environmental risk of genetically modified biocontrol bacteria in tomato rhizosphere. Fluctuation of culturable bacteria profile, microbial community struct...

Microbes and plants have evolved biochemical mechanisms to communicate with each other. The molecules responsible for such communication are secreted during beneficial or harmful interactions. Hundreds of these molecules secreted into the rhizosphere have been identified, and their functions are being studied in order to understand the mechanisms of interaction and communication among the diffe...

The rhizosphere is known to provide ecologically favourable niche for most of the beneficial soil microorganisms. The rich microbial activity in the rhizosphere aids in several biological and ecological processes important for plant health. The abundance of nitrogen fixing, phosphate solubilising and plant disease suppressing bacteria in the rhizosphere of crop plants assumes a natural signific...

Through field investigation and experimental analysis, the forms, contents distribution of heavy metals (Zn, Pb, Cu, Cd, Ni, Cr) in rhizosphere non-rhizosphere soils Miscanthus floridulus growing everywhere Tielongwei mine pond (sample plot 1), Caoduikeng tailings 2), Donghua 3) Small 4) Dabaoshan, Guangdong Province were studied. The results showed that main forms distributions are basically s...

White clover (Trifolium repens) is the key legume component of New Zealand pastoral agriculture due to the high quality feed and nitrogen inputs it provides. Invertebrate pests constrain white clover growth and this study investigated rhizosphere-associated fungal controls for two of these pests and attempts to disentangle the underpinning mechanisms. The degree of suppressiveness of 10 soils, ...

Previous research in our laboratory revealed that the introduction of Bacillus cereus UW85 can increase the populations of bacteria from the Cytophaga-Flavobacterium (CF) group of the Bacteroidetes phylum in the soybean rhizosphere, suggesting that these rhizosphere microorganisms have a beneficial relationship (G. S. Gilbert, J. L. Parke, M. K. Clayton, and J. Handelsman, Ecology 74:840-854, 1...

The soil-borne pathogen Rhizoctonia solani is responsible for crop losses on a wide range of important crops worldwide. The lack of effective control strategies and the increasing demand for organically grown food has stimulated research on biological control. The aim of the present study was to evaluate the rhizosphere competence of the commercially available inoculant Bacillus amyloliquefacie...

or a suppressive influence on SOM decomposition (Van Veen et al., 1991; Cheng, 1999). As a measure of main Plant species and soil fertility presumably control rhizosphere efenergy use for the acquisition of belowground resources fects on soil organic matter (SOM) decomposition, but qualitative (e.g., nutrients and water), rhizosphere respiration may and quantitative descriptions of such control...
