Endophytes colonize an ecological niche similar to that of phytopathogens, which make them candidate for disease suppression. Anthracnose is a disease caused by Colletotrichum spp., a phytopathogen that can infect guarana (Paullinia cupana), an important commercial crop in the Brazilian Amazon. We investigated the diversity of endophytic bacteria inhabiting the phyllosphere of asymptomatic and ...

BACKGROUND Most endophytic bacteria in consortia, which provide robust and broad metabolic capacity, are attractive for applications in plant metabolic engineering. The aim of this study was to investigate the effects of engineered endophytic bacterial strains on rice sprout ethylene level and growth under saline stress. A protocol was developed to synthesize engineered strains by expressing ba...

biofertilizer is a substance which contains living microorganisms which can use instead of chemical fertilizer in sustainable crop production. the effects of phosphate solubilizing bacteria; root endophytic fungi (ef) piriformospora indica, and arbuscular mycorrhizal fungus (amf) glomus mosseae on growth and nutrient uptake of sunflower plants grown in mixture with two clover species, persian c...

Viscum album and its endophytic fungal species lectin are reported as antioxidant, antimicrobial, anti-inflammatory and anticancer activity. The present investigation was undertaken to in vitro (by enzymes inhibition) and in vivo antidiabetic activity of endopytic fungi, Alternaria species N-acetyl-galactosamine, 54 kDa protein lectin in alloxan induced diabetes in rats. Endophytic fungal lecti...

Endophytic microorganism live inter or intra cellularly in most of the plant tissues without causing any disease symptoms. Endophytes are known to produce plant growth promoting compounds. Cytokinin is a group of plant growth regulators (PGRs) and can be exploited in agriculture for both pre-harvest and postharvest management of leafy vegetables, fruits and cut flowers. The objective of this st...

This study provides new insights into the dynamics of bacterial community structure during phytoremediation. The communities of cultivable autochthonous endophytic bacteria in ryegrass exposed to polycyclic aromatic hydrocarbons (PAHs) were investigated with regard to their potential to biodegrade PAHs. Bacterial counts and 16S rRNA gene sequence were used in the microbiological evaluation. A t...

This study investigated the potential of indigenous endophytic bacteria to improve the efficiency of the wetland helophyte Juncus acutus to deal with a mixed pollution consisting of emerging organic contaminants (EOCs) and metals. The beneficial effect of bioaugmentation with selected endophytic bacteria was more prominent in case of high contamination: most of the inoculated plants (especially...

Six endophytic fungi were isolated from Cupressus torulosa D.Don and identified phenotypically and genotypically. The fungal cultures were further grown and the culture was extracted by two organic solvents methanol and ethyl acetate. The screening was carried out using the agar well diffusion method against human pathogen such as Escherichia coli, Salmonella typhimurium, Bacillus subtilis and ...

The cause for the development of endophytic growth (nodular downgrowth) in rat urinary bladder epithelia cul tured in protein-free medium was traced to a deficiency of Ca in the culture medium. Endophytic growth, which is a characteristic in vivo histolÃ3gica! feature of the preneoplastic phase of experimental bladder cancer, was induced in vitro by 0.3 mm Ca2" but was suppressed by 1.8 rriM Ca...

Bacterial endophytes, non-pathogenic bacteria residing within plants, contribute to the growth and development of plants and their ability to adapt to adverse conditions. In order to fully exploit the capabilities of these bacteria, it is necessary to understand the extent to which endophytic communities vary between species and over time. The endophytes of Acer negundo, Ulmus pumila, and Ulmus...
