Plant growth promoting endophytic bacteria Burkholderia phytofirmans PsJN was used to investigate the potential to ameliorate the effects of drought stress on growth, physiology and yield of wheat (Triticum aestivum L.) under natural field conditions. Inoculated and uninoculated (control) seeds of wheat cultivar Sahar 2006 was sown in the field. The plants(More)
Salinity is one of the major environmental threats for successful crop production, hampering plant growth due to the osmotic effect and nutritional and hormonal imbalances. The application of naturally occurring plant growth-promoting rhizobacteria (PGPR) is an emerging technology aimed at ameliorating the negative impact of salinity. However, the results(More)
Burkholderia phytofirmans PsJN is a well-known plant growth-promoting bacterium that establishes rhizospheric and endophytic colonization in different plants. PsJN inoculation promotes growth of different horticultural crops. L-Tryptophan (L-TRP) application may further improve its effectiveness, due to substrate (L-TRP)-dependent inoculum (PsJN)-derived(More)
Phosphate solubilization, 1-aminocyclopropane-1-carboxylic acid (ACC)-deaminase activity and production of siderophores and indole acetic acid (IAA) are well-known traits of plant growth-promoting rhizobacteria (PGPR). Here we investigated the expression of these traits as affected by salinity for three PGPR strains (Pseudomonas fluorescens, Bacillus(More)
Salinity stress induces higher levels of ethylene in plants in arid and semi-arid regions. This increased concentration of ethylene can be inhibited by using plant growth promoting rhizobacteria (PGPR) containing ACC-deaminase. A pot trial was conducted under salt-stressed conditions to evaluate the potential of combined application of Rhizobium phaseoli(More)
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(More)
Allelopathy is an important mechanism of plant interference mediated by the release of plant-produced secondary metabolites or decomposition products of microbes to the aerial or soil environment. It plays a key role in natural as well as cultivated ecosystems. Allelochemicals are released into the soil rhizosphere by a variety of mechanisms, including(More)
