IAA production is among the most important mechanisms used by PGPB to improve plant growth, health, and productivity. Out of twenty-eight telluric bacterial isolates, the four producing high IAA amounts were identified by 16S rDNA gene sequencing as Bacillus subtilis (A7), Bacillus pumilus (E11), and Pseudomonas fluorescens (A5 and E9). IAA product...

In a context of a changing environment, it is crucial to maximize our knowledge on all the mechanisms involved in plant microbiome interactions at the genetic, physiological, and ecological levels. This chapter reviews some recent advances in plant microbiome investigations and describes potential applications of such associations for the mitigatio...

Cystoseira mediterranea (Sauv.) extract was tested for its ability to restore barley (Hordeum vulgare) growth under salt stress (350 mM NaCl), shoot growth; membrane integrity; lipid peroxidation and hydrogen peroxide determination were performed. In normal conditions, the obtained data revealed the ability of the extract to stimulate most of barle...

Human efforts to develop agriculture have been known for a long time. Since becoming aware of the importance of this field, farmers and researchers have not ceased looking for methods and products to improve crop productivity and quality and to protect it from various aggressions and stress that it might undergo. Mechanisms using microbes as biofer...

Saline soils are among the big obstacles in agricultural activities in arid and semiarid regions. Numerous cultivated areas in the world’s irrigated soils are severely affected by both of salinity and salinization. Therefore, the development and sustainability of profitable agricultural systems are seriously threatened. Sustainable and cost-effecti...

Elevated concentration of salinity hinders plant life from germination to final step. So, numerous mechanisms are inhibited, such as phytohormone synthesis, nutrient uptake, root and shoot regulation, photosynthesis, and DNA replication. It is well documented that the plant growth-promoting bacteria/rhizobacteria (PGPB/R) colonize plants and stimul...

Using dry algal materials and “algae-bacterium” combination to restore plant growth under heavy metal stress has rarely been considered. Herein, Cystoseira sp. and Enteromorpha intestinalis seaweeds were tested for their ability to restore plant and bacterial growth at high cadmium concentrations. The bacterial isolates (N5 and E5) tolerate high Cd...

Algerian coast contains a high species diversity of marine algae; however, there are only few reports on their bio-stimulant properties. Different concentrations of the brown seaweed Cystoseira mediterranea. Extracts were used to determine their efficiency as biostimulant of barley growth and productivity. All growth parameters and chlorophyll cont...

Different bacterial groups in irrigation well water are strongly implicated in soil health and plant development. Herein, 48 bacterial strains were isolated from agricultural well water in northern Algeria. Among them, four strains were selected based on their antifungal potential and their ability to express Plant Growth Promoting traits such as I...

Using beneficial bacteria to control plant pathogens has become an ecofriendly alternative to the excessive use of chemicals. In this investigation, a bacterial strain RhiNA, isolated from an agricultural land in northern Algeria (Bejaia), was selected based on its ability to produce antifungal and plant growth promoting (PGP)-metabolites. It was t...

In this investigation, the isolate S7LiBe isolated from trefoil rhizosphere in Barbacha, Bejaia (northern Algeria), was selected on the basis of plant growth promoting attributes. This isolate identified as Bacillus sp. based on 16SrDNA sequence analysis, exhibits the highest similarity of 99.1% with Bacillus pichinotyi AF519463 andAF519460 and Bac...

Ce travail porte sur la recherche des bactéries productrices de métabolites d’intérêt agricole. Dans cette optique, la souche bactérienne nommée J16, a été isolée à partir d’un sol agricole rhizosphérique de la wilaya de Bejaïa (Algérie) et a été identifiée comme Dietzia sp. (Actinobactérié). Cette souche a montré plusieurs activités d’intérêt agri...

The plant growth promoting effect of bacterial isolates from salt-affected agricultural rhizospheric soil from Bejaia, Algeria, on barley seedlings as well as biological control abilities of these isolates against phytopathogenic fungi were determined. Four isolates stimulated significantly germination and growth of barley seedlings in an axenic te...
