Soil microorganisms, such as plant growth-promoting rhizobacteria (PGPR), play crucial roles in plant growth, but their influence on plant water relations remains poorly explored. We studied the effects of native soil microorganisms and inoculation with the PGPR strain Aur6 of Pseudomonas fluorescens on water stress responses of seedlings of the drought-avoiding Pinus halepensis Mill. and the d...

background: the stresses elderly face in various situations are different from those faced by other age groups. they are at a stage in life where they may face extended and critical health problems. in general, aging adults are vulnerable to the harmful effects of a negative stressor factors. this study was conducted to evaluate the effects of precede model-based educational program on level of...

Aims: The aim of this study was to evaluate the effect of stress inoculation on laboratory markers such as heart rate variability and salivary cortisol and clinical outcomes (anxiety, stress and depression) of patients undergoing coronary artery bypass graft surgery.  Methods & Materials: The research is a semi experimental study with the pre, post-test and experimental and control groups. The...

To compensate for stress imposed by salinity, biofilm formation and exopolysaccharide production are significant strategies of salt tolerant bacteria to assist metabolism. We hypothesized that two previously isolated salt-tolerant strains Halomonas variabilis (HT1) and Planococcus rifietoensis (RT4) have an ability to improve plant growth, These strains can form biofilm and accumulate exopolysa...

to evaluate the effect of arbuscular mycorrhiza (glomus mosseae) under salt stress on physiological and some nutrient absorption in new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with three replications (three pots for each replication) in greenhouse in shahrekord university in 2014. treatments were inoculation of substrate with three levels of arb...

A wide range of C3 and C4 plant species could acclimatize and grow under the impact of salinity stress. Symbiotic relationship between plant roots and arbuscular mycorrhizal fungi (AMF) are widespread and are well known to ameliorate the influence of salinity stress on agro-ecosystem. In the present study, we sought to understand the phenomenon of variability on AMF symbiotic relationship on sa...

Soybean is an important oil crop with multiple uses. Soybeans can grow in various soil types and climates; however, salt stress reduces their yield. Plant growth-promoting microorganisms are environmentally benign way to combat boost plant tolerance. In the present study, we have identified bacteria that produce indole acetic acid (IAA) induce distinct growth characteristics soybean plants unde...

Chili pepper (Capsicum frutescens L.) is a common commodity used as spice and pharmaceutical uses around the world. However, chili cultivation failure often occurs due to drought exposure. The inoculation of arbuscular mycorrhizal fungi (AMF), such Funneliformis mosseae, has potential induce defense against stress through symbiotic association with plant roots. aim this research was investigate...
