Microbes living symbiotically in plant tissues mutually cooperate with each other by providing nutrients for proliferation of the partner organism and have a beneficial effect on growth. However, few studies thus far examined interactive endophytic bacteria arbuscular mycorrhizal fungi (AMF) hostile conditions their potential to improve stress tolerance. In this study, we investigated how synergistic interactions AMF affect growth, nodulation, nutrient acquisition tolerance Acacia gerrardii...
Salinity causes disturbance in symbiotic performance of plants, and increases susceptibility plants to soil-borne pathogens. Endophytic bacteria are an essential determinant cross-tolerance biotic abiotic stresses plants. The aim this study was isolate non-rhizobial endophytic from the root nodules chickpea (Cicer arietinum L.), assess their ability improve plant growth performance, control rot under saline soil conditions. A total 40 bacterial isolates internal tissues grown salinated were...
Abstract Drought stress is the major abiotic factor limiting crop production. Co-inoculating crops with nitrogen fixing bacteria and plant growth-promoting rhizobacteria (PGPR) improves growth increases drought tolerance in arid or semiarid areas. Soybean a source of high-quality protein oil for humans. It susceptible to conditions. The co-inoculation drought-stressed soybean nodulating rhizobia root-colonizing, PGPR root shoot growth, formation nodules, fixation capacity soybean. present...
Plant secondary metabolites play vital role in plant stress response. In this study we investigated whether root colonization of tomato (Solanum lycopersicum) infected by Trichoderma harzianum leads to alterations the biosynthesis including phytohormones and osmolyte proline under drought stress. Exposure caused a drastic decline growth physiological parameters. Tomato inoculated with T. showed increased shoot chlorophyll pigments as compared uninoculated controls well stressed plants....
Medicinal plants are known to harbor potential endophytic microbes, due their bioactive compounds. In a first study of ongoing research, bacteria were isolated from two medicinal plants,
It is a well accepted strategy to improve plant salt tolerance through inoculation with beneficial microorganisms. However, its underlying mechanisms still remain unclear. In the present study, hydroponic experiments were conducted evaluate effects of Bradyrhizobium japonicum USDA 110 salt-tolerant Pseudomonas putida TSAU1 on growth, protein content, nitrogen, and phosphorus uptake as root system architecture soybean (Glycine max L.) under stress. The results indicated that combined...
Experiments were conducted to evaluate cadmium (Cd) stress-induced changes in growth, antioxidants and lipid composition of Solanum lycopersicum with without arbuscular mycorrhizal fungi (AMF). Cadmium stress (50 μM) caused significant the growth physio-biochemical attributes studied. AMF mitigated deleterious impact Cd on parameters increased malonaldehyde hydrogen peroxide production but reduced these by mitigating oxidative stress. The activity antioxidant enzymes enhanced under treatment...
The application of biochar to soil is considered have the potential for long-term carbon sequestration, as well improving plant growth and suppressing pathogens. In our study we evaluated effect on soybeans, composition root-associated bacteria with promoting traits. Two types biochar, namely, maize (MBC), wood (WBC), hydrochar (HTC) were used pot experiments monitor growth. Soybean plants grown in amended HTC char (2%) showed best performance collected isolation further characterization...
The effectiveness of plant growth – promoting bacteria is variable under different biotic and abiotic conditions. Abiotic factors may negatively affect the beneficial properties efficiency introduced PGPR inoculants. aim this study was to evaluate effect rhizobacteria on control foot root rot tomatoes caused by Fusarium solani soil salinity Among five tested strains, only Pseudomonas chlororaphis TSAU13, extremorientalis TSAU20 were able stimulate act as biological controls disease tomato....
Gradual depletion in soil nutrients has affected fertility, nutrients, and the activities of enzymes. The applications multifarious rhizobacteria can help to overcome these issues, however, effect co-inoculation plant-growth promoting (PGPR) biochar on growth andnutrient levelsin soybean level enzymes needs in-depth study. present study aimed evaluate Bradyrhizobium japonicum USDA 110 Pseudomonas putida TSAU1 different levels (1 3%) parameters nutrient Effect plant biochemicals were studied...
The composition of the mammalian gut bacterial communities can be influenced by introduction environmental bacteria in their respective habitats. However, there are no extensive studies examining interactions between bacteriome and wild mammals. Here, we explored relationship pika (Ochotona spp.) related across host species altitudinal sites using 16S rRNA gene sequencing. Plateau pikas (O. curzoniae) Daurian daurica) were sampled at five different sites, plant soil samples collected each...
The presented experiments evaluated the symbiotic performance of soybean genotypes with contrasting salt stress tolerance to arbuscular mycorrhizal fungi (AMF) inoculation. In addition, physiological mechanisms in plants derived from mutualistic interactions between AMF and host were evaluated. Plant growth, nodulation, nitrogenase activity levels endogenous growth hormones, such as indole acetic acid butyric acid, salt-tolerant salt-sensitive significantly decreased at 200 mM NaCl....
Understanding the symbiotic performance of rhizobia and responses plant root systems to mineral nutrient supply will facilitate development strategies enhance effective rhizobia-legume symbioses. Interactive effect nitrogen (N), phosphorus (P) magnesium (Mg) on soybean (Glycine max L.) with Bradyrhizobium japonicum, nodulation, architecture N concentration in tissue under hydroponic conditions were studied. Plant growth was significantly higher a high combined Mg (HNHMg) than combination P...
