Salinity is a major environmental stress that limits crop production worldwide. In this study, we characterized plant growth-promoting rhizobacteria (PGPR) containing 1-aminocyclopropane-1-carboxylate (ACC) deaminase and examined their effect on salinity stress tolerance in okra through the induction of ROS-scavenging enzyme activity. PGPR inoculated okra plants exhibited higher germination per...
Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance plant growth by a wide variety of mechanisms like phosphate solubilization, siderophore production, biological nitrogen fixation, rhizosphere engineering, production of 1-Aminocyclopropane-1-carboxylate deaminase (ACC), quorum sensing (QS) signal interference and inhibition of biofilm formation, phytohormo...
Field experiments were conducted to evaluate growth promotion and induced systemic disease resistance (ISR) in cucumber mediated by plant growth-promoting rhizobacteria (PGPR) with and without methyl bromide soil fumigation. In both fumigated and nonfumigated plots, numbers of cucumber beetles, Acalymma vittata (F.), and the incidence of bacterial wilt disease, caused by the beetle-transmitted ...
indole acetic acid is an important hormone that improved the growth of different plant organs such as the root under normal and stress conditions. as various studies have shown, most of rhizobacteria produce indole acetic acid and thereby contribute to the growth of plants. in this study, different rhizobacteria were isolated from different regions of iran for the assessment of their ability to...
This study was carried out to investigate the effects of plant growth promoting rhizobacteria (PGPR) on the antioxidant status, photosynthesis, mineral content and growth of lettuce (Lactuca sativa L.) under different soil salinity conditions. Increasing salinity in the soil decreased plant growth, photosynthesis, stomatal conductance, chlorophyll content, and mineral uptake compared to soil wi...
آرسنیک یکی از سمی ترین آلاینده های موجود در خاک و آب¬های زیرزمینی است که سلامتی انسان و سایر موجودات زنده را به خطر می اندازد. کلزا یکی از گیاهان بیش اندوز آرسنیک معرفی شده است. امروزه از باکتری¬های محرک رشد (plant growth promoting rhizobacteria, pgpr ) به عنوان ابزاری در راستای افزایش تحمل گیاه به شرایط نامناسب محیطی از جمله آلودگی به فلزات سنگین استفاده می شود. در این تحقیق میزان تاثیر استفاد...
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). ...
one of the important mechanisms utilized by the plant growth promoting rhizobacteria (pgpr) is lowering of ethylene levels by the 1-aminocyclopropane-1-carboxylic acid (acc) deaminase enzyme. the mechanism facilitates plant growth and development in the stress conditions. pgpr containing acc deaminase can promote plant growth under stress and overcome the harmful effects. the study aimed to scr...
background: plants infection with microorganisms as well as physical factors such as osmotic stresses especially drought stress induced particular secondary metabolite production. objective: plant root and shoot hyoscyamine (hyo) and scopolamine (sco) variations were investigated under three water deficit stress (wds) levels as 30 (w1), 60 (w2) and 90 % (w3) water depletion of field capacity an...
