ability for plant growth promotion and effective disease management properties, root colonization by Pseudomonas fluorescens, biotic and abiotic factors affecting colonization and mechanisms of pathogen suppression. INTRODUCTION Cotton (Gossypium hirsutum L.) is the third largest impor-tant economic crop in India produced for cloth and other kind of things of human need serving many other impor-tant uses (Hutchinson et al., 1947). Two independent experiments were conducted in consecutive seasons to evaluate the ability of P. fluorescens PICF7 to promote plant growth and to increase yield in barley and wheat. growth, number of leaves were enhanced by the combination of both of the bacteria than their individual formulations. Diverse mechanisms are involved in the suppression of plant pathogens, which is often indirectly connected with plant growth. Citing Literature . Plant growth promotion by Pseudomonas fluorescens : mechanisms, genes and regulation: Author(s) Cheng, X. The efficacy of bacterial antagonists in controlling fungal diseases was often better as alone, and sometimes in combination with fungicides. A cold resistant mutant of Pseudomonas fluorescens ATCC 13525 was developed, which could grow equally well at 25 and 10 °C and its effect on plant growth promotion under in vitro and in situ conditions was observed. Front. Plant Sci. The Pseudomonas fluorescens strain UM270 was isolated form the rhizosphere of wild Medicago spp. : P. fluorescens is a bacterial species of the genus Pseudomonas, and it is a plant growth promoting bacterium. Among the method of application tested in our study, soil application was found to be the best in yielding better results of plant growth promotion. Whereas members of the bacterial genera Azospirillum and … The sequence covers 6,047,974 … Many of these rhizobacteria are symbionts and provide plant growth promotion (PGP) services, protecting the plant from biotic and abiotic stresses and increasing plant productivity by providing access to nutrients that would otherwise be unavailable to roots. It is not clear exactly how the plant growth-promoting properties of P. fluorescens are achieved; theories include: The bacteria might induce systemic resistance in the host plant, so it can better resist attack by a true pathogen. February 2018; DOI: 10.1016/B978-0-444-63987-5.00010-4. The efficacy of bacterial antagonists in controlling fungal diseases was often better as alone, and sometimes in combination with fungicides. of Volatile Production by Plant Growth-Promoting Pseudomonas fluorescens SBW25. A free living Plant growth promoting rhizobacteria (PGPR) Pseudomonas fluorescens are able to colonize around plant root and incorporate free atmospheric molecule into plant absorbable nutrient form along with improved plant growth and crop yield. Direct plant growth promotion by microbes is based on improved nutrient acquisition and hormonal stimulation. In the current study, we aimed to elucidate the plant growth-promoting characteristics of Pseudomonas psychrotolerans CS51 under heavy metal stress conditions (Zn, Cu, and Cd) and determine the genetic makeup of the CS51 genome using the single-molecule real-time (SMRT) sequencing technology of Pacific Biosciences. 2001).
