Download or read book Multilateral Interactions In The Rhizosphere written by Soumitra Paul Chowdhury and published by Frontiers Media SA. This book was released on 2023-09-05 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rhizosphere is an ecological hotspot. Plant roots, bacteria, archaea, fungi, nematodes, and other macroscopic organisms interact here with each other. Plants represent the main influencing force as they produce a mixture of chemical molecules and extrude them in the form of root exudates. Those exudates determine not only the nutrient availability of the plant but also influence the outcome of the interactions in the vicinity of the roots. In response to the plant-derived signals, a subset of the bulk soil microbes can proliferate in the proximity of the root and some of them can eventually overcome the plant defense system to colonize the plants. The root-associated microbiota is assumed to be crucial for plant health, and belowground plant-microbe and microbe-microbe interactions can result in altered growth and nutritional quality of the aboveground plant parts. Such interactions affect community composition and productivity in natural ecosystems or crop yield in agricultural fields. Root associations with plant growth-promoting rhizobacteria (PGPR) producing phytohormones that alter root architecture, or produce antibiotics to suppress antagonistic pathogens, affecting nutrient availability and competition between plants are just a few among many examples of such belowground interactions in the rhizosphere. Moreover, the role of rhizosphere microorganisms in stimulating the plant immune system leading to Induced Systemic Resistance (ISR) has also been a focus of an active investigation. However, the molecular mechanisms are still largely unknown. On one hand, it has been proposed that plants actively recruit beneficial microorganisms under certain pathological conditions or influence the soil microbial communities and create a so-called “soil memory”, which is conveyed to future plant generations. On the other, the presence and interactions between microorganisms in the soil have a substantial impact on plant health.

Download or read book The Prokaryotes written by Edward F. DeLong and published by Springer. This book was released on 2014-10-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea

This book was released on 2006-03-22 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rhizosphere is a very complex environment in which the effects of the plant on soil microorganisms and the effects of the microorganisms on the plant are interacting and are interdependent. Plant root exudates and breakdownproducts attract microbes and feed them and, in turn, the plants often bene?t from the microbes. Interactions among microorg- ismsandplantrootsareessentialfornutritionalrequirementsoftheplant. Plant growth, development and productivity are largely dependent on the soil environment in the root region rhizosphere. The new techniques of studying the rhizosphere enables us to get a much better understanding of the dynamics of the rhizosphere population, such rhizosphere studies beingofinteresttoagriculturists,soilbiologists,chemists,microbiologists andmolecularbiologists. The rhizosphere microbes in?uence the root environment in several ways. They may change the oxidation-reduction potential, in?uence the availabilityofmoistureandnutrients,producegrowthinhibitingorgrowth promoting substances in the form of exudates, provide competition and possiblyinducemanyothereffects.Mycorrhizalassociationsarebene?cial in mineral uptake and in increasing root surface area for effective ion absorption. Antagonism,competitionandsynergisminsoilandtherhizoplane(r- zosphere) are the most important microbial interactions to consider in the study of rhizosphere biology. With the growing information on the production of growth regulators, competitiveness of the microbes in the rhizosphere, microsymbionts, and other factors, their effect upon plant growth will become more evident. Experiments on the introduction of microbes or their products in the rhizosphere will help to improve our understandingofthebiologyoftherhizosphere.

This book was released on 2017-01-10 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing demographic trends require sustainable technologies to improve quality and yield of future food productions. However, there is uncertainty about plant protection strategies in many agro-ecosystems. Pests, diseases, and weeds are overwhelmingly controlled by chemicals which pose health risks and cause other undesirable effects.Therefore, an increasing concern on control measures emerged in recent years. Many chemicals became questioned with regard to their sustainability and are (or will be) banned. Alternative management tools are studied, relying on biological, and low impact solutions. This ResearchTopic concerns microbial biocontrol agents, root-associated microbiomes, and rhizosphere networks. Understanding how they interact or respond to (a)biotic environmental cues is instrumental for an effective and sustainable impact. The rhizosphere is in this regard a fundamental object of study, because of its role in plant productivity. This e-book provides a polyhedral perspective on many issues in which beneficial microorganisms are involved. Data indeed demonstrate that they represent an as yet poorly-explored resource, whose exploitation may actively sustain plant protection and crop production. Given the huge number of microbial species present on the planet, the microorganisms studied represent just the tip of an iceberg. Data produced are, however, informative enough about their genetic and functional biodiversity, as well as about the ecosystem services they provide to underp in crop production. Challenges for future research work concern not only the biology of these species, but also the practices required to protect their biodiversity and to extend their application in the wide range of agricultural soils and systems present in the world. Agriculture cannot remain successfully and sustainable unless plant germplasm and useful microbial species are integrated, a goal for which new knowledge and information-based approaches are urgently needed.

Download or read book Microbial Cross talk in the Rhizosphere written by Benjamin A. Horwitz and published by Springer Nature. This book was released on 2022-06-08 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the cross-talk between plants and microbes in the rhizosphere. The rhizosphere is the hotspot of microbial activities that influence plant growth and crop yield. The rhizosphere-residing microbes include the nitrogen-fixing rhizobia, mycorrhizal fungi, antibiotic-producing bacteria, antagonistic, plant-beneficial fungi, and entomopathogens. The three-way cross-talk among the plants, the pathogens and other microbes involves signaling molecules, metabolites, and physical interactions. The book also describes deleterious and beneficial aspects of this communication between plants and microbes. Plants program the local microbiome near their roots, and the microbial community has a profound influence on the functioning of the plant. This complex communication makes the collection of chapters a timely one, because the diverse subjects are linked by their focus on the molecular language of plant-microbe cross-talk. This timely and informative book is useful for students and researchers in the fields of microbiology, soil biology, and plant pathology.

Download or read book Plant Microbe Interactions written by B.B. Biswas and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen tremendous progress in unraveling the molecular basis of different plant-microbe interactions. Knowledge has accumulated on the mecha nisms of the microbial infection of plants, which can lead to either disease or resistance. The mechanisms developed by plants to interact with microbes, whether viruses, bacteria, or fungi, involve events that can lead to symbiotic association or to disease or tumor formation. Cell death caused by pathogen infection has been of great interest for many years because of its association with plant resistance. There appear to be two types of plant cell death associated with pathogen infection, a rapid hypersensitive cell death localized at the site of infection during an incompatible interaction between a resistant plant and an avirulent pathogen, and a slow, normosensitive plant cell death that spreads beyond the site of infection during some compatible interactions involving a susceptible plant and a virulent, necrogenic pathogen. Plants possess a number of defense mechanisms against infection, such as (i) production of phytoalexin, (ii) formation of hydrolases, (iii) accumulation of hydroxyproline-rich glycoprotein and lignin deposition, (iv) production of pathogen-related proteins, (v) produc tion of oligosaccharides, jasmonic acid, and various other phenolic substances, and (vi) production of toxin-metabolizing enzymes. Based on these observations, insertion of a single suitable gene in a particular plant has yielded promising results in imparting resistance against specific infection or disease. It appears that a signal received after microbe infection triggers different signal transduction pathways.

Download or read book Genes Involved in Microbe Plant Interactions written by D.P.S. Verma and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interdependence between species is a law of nature. The degree of this interdependence is vividly evident in the plant-microbial world. Indeed, there is no axenic plant in nature and one finds various forms of interac tions between these two kingdoms ranging from completely innocuous to obligate parasitic. Most of these interactions are poorly understood at the molecular and physiological levels. Only those few cases for which a molecular picture is emerging are discussed in this volume. With the advent of recombinant DNA technology and the realization that some of these interactions are very beneficial to the host plant, a spate of activity to understand and manipulate these processes is occurring. Microbes interact with plants for nutrition. In spite of the large number of plant-microbe interactions, those microbes that cause harm to the plants (i. e. , cause disease) are very few. It is thus obvious that plants have evolved various defense mechanisms to deal with the microbial world. The mecha nisms for protection are highly diverse and poorly understood. Some pathogens have developed very sophisticated mechanisms to parasitize plants, an excellent example for this being crown gall caused by a soil bac terium, Agrobacterium tumefaciens. A remarkable ingenuity is exhibited by this bacterium to manipulate its host to provide nitrogenous compounds which only this bacterium can catabolize. This is carried out by a direct gene transfer mechanism from bacteria to plants.
