the root endophytic fungus, piriformospora indica, colonizes roots of a large number of plant species including cereals and brasicaceae. there are several reports indicating that p. indica protects roots from different path-ogens. in the present study, rice plants were pre-inoculated with p. indica and were subsequently infected with fusarium proliferatum, as the causal agent of root rot and cr...

Salinity is one of the major limitations for food production worldwide. Improvement of plant salt-stress tolerance using plant-growth promoting rhizobacteria (PGPR) has arisen as a promising strategy to help overcome this limitation. However, the molecular and biochemical mechanisms controlling PGPR/plant interactions under salt-stress remain unclear. The main objective of this study was to obt...

Soil salinity, being a part of natural ecosystems, is an increasing problem in agricultural soils throughout the world. Pseudomonas frederiksbergensis OS261 has already been proved to be an effective bio-inoculant for enhancing cold stress tolerance in plants, however, its effect on salt stress tolerance is unknown. The main aim of the present study was to elucidate P. frederiksbergensis OS261 ...

in order to assess drought tolerance of mycorrhizal petunia plants (petunia hybrida cv. mix), a greenhouse experiment was carried out with two different mycorrhizae species (glomus mosseae and glomus intraradices) applied singly or in combination at two phosphorous (p) levels (0 and 100 mg kg-1 dry soil) and three irrigation regimes (100% field capacity (fc) as control, 75% fc producing moderat...

BACKGROUND Switchgrass is one of the most promising bioenergy crop candidates for the US. It gives relatively high biomass yield and can grow on marginal lands. However, its yields vary from year to year and from location to location. Thus it is imperative to develop a low input and sustainable switchgrass feedstock production system. One of the most feasible ways to increase biomass yields is ...

A maize rhizosphere isolate was phenotypically and genotypically characterized and identified as Enterobacter spp. bacterium. Germinated seeds were inoculated, the plantlets were sown in vermiculite and in soil and grown under laboratory and field conditions, respectively. The adherence, colonization and plant growth promotion capability of Enterobacter sp. UAPS03001 was evaluated in "Rojo-Crio...

Perennial ryegrass (Lolium perenne) is an important forage grass with high yield and superior quality in temperate regions which is widely used in parks, sport field, and other places. However, perennial ryegrass is moderately tolerant to salinity stress compared to other commercial cultivars and salt stress reduces their growth and productivity. Aspergillus aculeatus has been documented to par...

Salinity is a major environmental stress that limits crop production worldwide. In this study, we characterized plant growth-promoting rhizobacteria (PGPR) containing 1-aminocyclopropane-1-carboxylate (ACC) deaminase and examined their effect on salinity stress tolerance in okra through the induction of ROS-scavenging enzyme activity. PGPR inoculated okra plants exhibited higher germination per...

The production and consumption of blueberry have increased in Mexico owing to its health benefits. Symbiotic relationships been shown be crucial plants. In particular, phytohormone by Pseudomonas fluorescens is an important mechanism plant growth promotion. However, there are only a few reports on the effects growth-promoting bacteria blueberries. Therefore, we aimed evaluate four strains P. (U...
