Crop management systems influence plant productivity and nutrient use efficiency, as well as plant growth-promoting rhizobacteria (PGPR), which are known to influence the growth of plants via phytohormone production, phosphate solubilization, nitrogen (N) fixation and antimicrobial activity. The objective of this study was to compare the influence of two crop management system on microbial PGPR...

The present study evaluated the effect of nanochitosan in combination with plant growth promoting rhizobacteria (PGPR), PS2 and PS10 on maize growth. The PGPR were earlier recognized as Bacillus spp. on the basis of 16S rDNA sequencing. The observation revealed enhanced plant health parameters like seed germination (from 60 to 96.97%), plant height (1.5-fold increase), and leaf area (twofold). ...

Interactions between plants and microorganisms in the rhizosphere (rhizobacteria) can clearly affect crop yields. Rhizobacteria that benefit plant growth and development are called PGPR. the most studied PGPR belong to gramnegative genera, and the greatest number of strains are members of the fluorescent pseudomonads in our present investigation was to study the plant growth promoting (PGP) act...

نیتروژن یکی از مهم‏ترین عناصر غذایی در گیاهان است که کمبود آن در خاک از عوامل اصلی محدود کننده‏ رشد گیاهان می‏باشد. این در حالیست که در حدود 78 درصد از گاز موجود در اتمسفر، گاز مولکولی نیتروژن بوده که به صورت مستقیم برای گیاهان قابل جذب نمی‏باشد. یکی از مهم‏ترین راه‏های تثبیت نیتروژن موجود در اتمسفر، برقراری همزیستی بین گیاهان لگوم و باکتری‏های ریزوبیوم می‏باشد. کودپاشی مراتع به‏خصوص در مناطق خ...

Brevibacillus brevis DZQ7 is a plant growth-promoting rhizobacterium (PGPR) isolated from tobacco rhizosphere. Here, we report the draft genome sequence of B. brevis DZQ7. Several functional genes related to antimicrobial activity were identified in the genome.

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...

Investigations were conducted to determine whether induction of PR-1a gene promoter was correlated with systemic resistance, induced by rhizobacteria, against wildfire disease of tobacco. Ten different strains of plant growth-promoting rhizobacteria (PGPR), including the species Bacillus pumilus, Serratia marcescens, Pseudomonas fluorescens, P. putida, Curtobacterium flaccumfaciens, and Bukhold...

ABSTRACT We evaluated combinations of two strains of plant growth-promoting rhizobacteria (PGPR) formulated with the carrier chitosan for the ability to induce growth promotion of tomato plants and resistance to infection by Cucumber mosaic virus (CMV). Each PGPR combination included GB03 (Bacillus subtilis) and one of the following PGPR strains: SE34 (B. pumilus), IN937a (B. amyloliquefaciens)...

The purpose of this study was to evaluate and assess the plant growth promoting characteristics and diversity of major tef rhizosphere isolates from central Ethiopia. A total of 162 bacteria were isolated from rhizosphere of tef [Eragrostis tef (Zucc.) Trotter] and characterized. While screening using some plant growth promoting characteristics, only about sixty six of the isolates were found t...
