Plant growth promoting rhizobacteria (PGPR) are diverse, naturally occurring bacteria that establish a close association with plant roots and promote the growth and immunity of plants. Established mechanisms involved in PGPR-mediated plant growth promotion include regulation of phytohormones, improved nutrient availability, and antagonistic effects on plant pathogens. In this study, we isolated...

A greenhouse experiment was performed to evaluate the effects of plant growth-promoting rhizobacteria (PGPR) on nodulation, biological nitrogen fixation (BNF) and growth of the common bean (Phaseolus vulgaris L. cv. Tenderlake). Single and dual inoculation treatments of bean with Rhizobium and/or PGPR were administered to detect possible changes in the levels of and interactions between the phy...

Management of drought stress through application plant growth promoting rhizobacteria (PGPR) is now considered as an effective strategy in the present scenario altered environmental conditions world. The aims and objectives investigation was isolation, characterization identification some potential microbial resources from drought-affected upland rice fields South Bengal followed by experimenta...

The rhizosphere of the great diversity plants is a complex ecosystem that houses thousands rhizobacteria promote plant growth. In current investigation, three bacteria were isolated from root Suaeda sp., which evaluated to determine ef fect their inoculation on Arabidopsis thaliana at distances 2 and 5 cm in divided boxes. test, we noticed Endo10(7) Endo10(5) stimulated more than control, while...

Auxin plays a key role in regulation of almost all processes of plant growth and development. Different physiological processes are regulated by different ranges of auxin concentrations; however, the underlying mechanisms creating these differences are largely unknown. The first step of auxin signaling is auxin-dependent interaction of an auxin receptor with transcriptional co-repressors (Aux/I...

1. Effects of chemical modifiers : p-chloromercuric benzoate (PCMB) ; N-ethylmaleimide (NEM) ; iodoacetic acid (IAA) ; 5,5-dithiobis-2-nitrobenzoate (DTNB) ; and dinitrofiuorobenzene (FDNB), and of metabolic inhibitors : NaCN; and 2,4-dinitrophenol (DNP) on taste responses in the chorda tympani of rats were studied. 2. PCMB, NEM, and IAA at optimum concentrations depressed the sucrose response ...

7-Hydroxy-2,3-dihydrobenzofuran derivatives, metabolites of a carbamate insecticide carbofuran, and five other phenolic inhibitors of indoleacetic acid (IAA) oxidase interfered with IAA-induced spectral change in the Soret band of horseradish peroxidase (HRP). The onset of IAA degradation required transformed HRP intermediates. The inhibitors, when added before IAA, protected HRP from reacting ...

Exogenously supplied indole-3-acetic acid (IAA) stimulated ethylene production in tobacco (Nicotiana glauca) leaf discs but not in those of sugar beet (Beta vulgaris L.). The stimulatory effect of IAA in tobacco was relatively small during the first 24 hours of incubation but became greater during the next 24 hours. It was found that leaf discs of these two species metabolized [1-(14)C]IAA quit...
