Background and objectives One of the main causes of plant growth and development disorders is the presence of adverse environmental conditions such as drought, which leads to stress in plants and endangers their survival. Recent research, however, recommends the use of soil microorganisms, especially plant growth-promoting bacteria, which are involved in plant growth as well as the nutrient cy...
Ladan Bayat 1, Mehri Askari*2 Department of Biology, Faculty of Science, Arak University (Received: 29 November 2012 Accepted: 4 May 2013) Abstract: Plant growth promoting rhizobacteria are beneficial bacteria that increase growth of plants and induce resistance to various stresses. SO2 air pollution is one of these stresses that is known as a strong damaging air pollutants. Pers...
A focus on the mechanisms by which ACC deaminase-containing bacteria facilitate plant growth.Bacteria that produce the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, when present either on the surface of plant roots (rhizospheric) or within plant tissues (endophytic), play an active role in modulating ethylene levels in plants. This enzyme activity facilitates plant growth especially...
Antioxidant response of cowpea co-inoculated with plant growth-promoting bacteria under salt stress.
Soil salinity is an important abiotic stress worldwide, and salt-induced oxidative stress can have detrimental effects on the biological nitrogen fixation. We hypothesized that co-inoculation of cowpea plants with Bradyrhizobium and plant growth-promoting bacteria would minimize the deleterious effects of salt stress via the induction of enzymatic and non-enzymatic antioxidative protection. To ...
introduction: increasing usage of chemical fertilizers imposes irreparable damages to the environment. disadvantages of chemical fertilizers has led to more attention to the application of organic fertilizers and manures. the use of organic fertilizers and livestock, especially in nutrient poor soils, it is necessary to maintain soil quality. plant growth promoting rhizobacteria (pgpr) occupy t...
the present study was conducted to determine the plant growth-promoting activities of bradyrhizobium sp. (vigna) strain mrm6 grown in the presence and absence of the selected herbicides, quizalafop-p-ethyl and clodinafop. the herbicide tolerant bradyrhizobium sp. (vigna) strain mrm6 was further tested for bioremediation and plant growth promoting potential using greengram as a test crop, grown ...
in order to investigate the effect of plant growth promoting rhizobacteria (pgpr) along with zinc (zn) and manganese (mn), foliar spraying on the morphological parameters of basil (ocimum basilicum l.) an experiment was conducted in factorial based on a randomized complete block design with three replications in 2011. treatments were the pgpr inoculation with azotobacter and azospirillum (azb+a...
Plant growth-promoting rhizobacteria (PGPR) are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. Inoculation of crop plants with certain strains of PGPR at an early stage of development improves biomass production through direct effects on root and shoots growth. Inoculation of ornamentals, forest trees, vegetables, and a...
