This paper addresses changes in plant gene expression induced by inoculation with plant-growth-promoting rhizobacteria (PGPR). A gnotobiotic system was established with Arabidopsis thaliana as model plant, and isolates of Paenibacillus polymyxa as PGPR. Subsequent challenge by either the pathogen Erwinia carotovora (biotic stress) or induction of drought (abiotic stress) indicated that inoculat...

The objectives of this study were to test the strain Wickerhamomyces anomalus WO2 as a plant growth-promoting yeast (PGPY), evaluate effect its inoculation on growth and physiological performance Suaeda fruticosa subjected salt stress, understand by which mechanism can protect from high salinity. results showed that is halophilic, grows at concentrations up 15%. Salinity caused decreases in chl...

Soil salinity is one of the most severe factors limiting nodulation, yield and physiological response in soybean. The possible role of plant growth promoting rhizobacteria (PGPR) in restricting mineral nutrients and thus alleviating soil salinity stress during plant growth has not yet been established. In this study, the beneficial effects of inoculation with salt-stressed PGPR strains were inv...

Plant growth-promoting rhizobacteria (PGPR) increase plant growth and crop productivity. The inoculation of plants with a bacterial mixture (consortium) apparently provides greater benefits to plant growth than inoculation with a single bacterial strain. In the present work, a bacterial consortium was formulated containing four compatible and desiccation-tolerant strains with potential as PGPR....

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. ...

Non-generic feedback refers to a specific event and implies that performance is malleable, while generic feedback implies that task performance reflects an inherent ability. The present study examined the influences of generic versus non-generic feedback on motor performance and learning in 10-year-old children. In the first experiment, using soccer ball kicking at a target as a task, providing...

Although many attempts have been made to inoculate successfully ,the lower animals with portions of tumors from human beings they 'have in the great majority of cases been without results. In some instances the observers have claimed that they have been successful }rot their statements are, as a rule, not convincing. Carl Lewin 1 discusses this question of transplantation at length and reviews ...

background: brief family interventions may have a positive impact on family caregivers of mental disorders. this study aimed to evaluate the effect of family psycho-education on depression, anxiety and stress in family caregivers of patients with mental disorders. methods: this randomized controlled trial designed and evaluated the effectiveness of a group psycho-educational program on 100 care...

Dipteryx alata Vogel (Fabaceae) is a fruit tree species native to the Cerrado with ecological and economic potential. However, water deficit can be limiting factor initial growth of this species, requiring knowledge on technologies that alleviate stressful effect. We hypothesized inoculation arbuscular mycorrhizae fungi contributes stress mitigation during after deficit. D. seedlings were subje...
