The present investigations were carried out to screen the PGPR isolates from five separate seasonal flower beds (Catharanthus roseus, Portulaca grandiflora, Celosia argentea, Gomphrena globosa and Impatiens balsamina) of Curzon Hall, University Dhaka. bacterial load collected soil samples ranged in between 7.60 ± 6.01 × 106 9.49 5.44× 108 cfu/g, 5.34 4.06×106 13.4 4.8×106 cfu/g 1.01 0.59×106 1....

Soil microorganisms with growth-promoting activities in plants, including rhizobacteria and rhizofungi, can improve plant health in a variety of different ways. These beneficial microbes may confer broad-spectrum resistance to insect herbivores. Here, we provide evidence that beneficial microbes modulate plant defenses against insect herbivores. Beneficial soil microorganisms can regulate hormo...

Abstract Many agricultural researches have been performed to improve soil productivity. Nitrogen (N) and Phosphorus (P) are essential elements which are utilized by the plants in large amounts. Phosphorus can be provided by applying chemical fertilizers. Microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this proces...

Plant growth promotion by rhizobacteria is a known phenomenon but the underlying mechanisms are poorly understood. We searched for plant growth-promoting rhizobacteria that are naturally associated with Arabidopsis thaliana to investigate the molecular mechanisms that are involved in plant growth-promotion. We isolated a Pseudomonas bacterium (Pseudomonas sp. G62) from roots of field-grown Arab...

The diversity of flora in Kalimantan influences the presence microbe-associated with rhizosphere on their activities and functions ecosystems. However, abiotic stress such as acidification, drought, toxic soil residues negatively impacted health plant growth some regions Kalimantan's soil. rhizobacteria, a group plant-growth-promoting rhizobacteria (PGPR), can colonize to produce natural produc...
