Plant growth-promoting rhizobacteria (PGPR) are bacteria that colonize plant roots and enhance plant growth by a wide variety of mechanisms. The use of PGPR in sustainable agriculture is steadily increasing and offers an attractive way to replace chemical fertilizers, pesticides, and supplements. PGPR have been applied to various crops to enhance growth, seed emergence, crop yield, and disease ...

ABSTRACT Plant growth-promoting rhizobacteria (PGPR) strains INR7 (Bacillus pumilus), GB03 (Bacillus subtilis), and ME1 (Curtobacterium flaccumfaciens) were tested singly and in combinations for biological control against multiple cucumber pathogens. Investigations under greenhouse conditions were conducted with three cucumber pathogens-Colletotrichum orbiculare (causing anthracnose), Pseudomon...

The aim of this study was to inventory the types of plant growth-promoting rhizobacteria (PGPR) present in the rhizosphere of plants grown in soils contaminated with heavy metals, recalcitrant organics, petroleum sewage or salinity in China. We screened 1223 isolates for antifungal activity and about 24% inhibited Rhizoctonia solani or Sclerotinia sclerotiorum. Twenty-four strains inhibitory to...

Systemic effect of two plant growth-promoting rhizobacterial (PGPR) strains,viz., Pseudomonas fluorescens (Pf4) and P. aeruginosa (Pag), was evaluated on pea (Pisum sativum) against the powdery mildew pathogen Erysiphe pisi. Foliar spray of the two PGPR strains was done on specific nodal leaves of pea and conidial germination of E. pisi was observed on other nodal leaves,distal to the treated o...

Plant health can be augmented by plant-growth-promoting rhizobacteria (PGPR) that confer biofertilizer, phytostimulation, and biocontrol activities. Herein, we provide the high-quality draft genome sequence of Serratia fonticola strain AU-AP2C, a Gram-negative motile PGPR of the pea plant, conferring phosphate solubilization, ammonia production, and antifungal activity against Fusarium sp. The ...

Rhizosphere is a wealthy location of microbes, ecological niche and should be explored for potential plant growth promoting rhizobacteria (PGPR), which developing as bioinoculants for interact with plant roots and enhancement of yield of crop plants. There are several plant growth promoting rhizobacterial (PGPR) inoculants that seems to promote plant growth through different mechanism such as I...

Replant problem is very serious problem which suppress growth and yield of apple and pear in all major fruit growing areas of the world. Fluorescent Pseudomonas has potential to synthesize different secondary metabolites with diverse PGPR activities which enhance soil fertility and promote plant growth. Under the present study twenty six Pseudomonas strains were isolated from the rhizosphere of...

Arbuscular mycorrhizal fungi (AMF) have a major impact on plant nutrition, defence against pathogens, a plant's reaction to stressful environments, soil fertility, and a plant's relationship with other microorganisms. Such effects imply a broad reprogramming of the plant's metabolic activity. However, little information is available regarding the role of AMF and their relation to other soil pla...
