This monograph provides an overview of beneficial plant-bacterial interactions in a straightforward and easy-to-understand format, and includes a wealth of unique illustrations elaborating every major point. Study questions that emphasize the key points are provided at the end of each chapter. One way to feed all of the people in the world’s growing population is through the increased use of plant-growth-promoting bacteria in agriculture. These bacteria not only directly promote growth but also protect plants against a wide range of biotic and abiotic stresses. Moreover, they can be used to support procedures for biologically cleaning up the environment. Plant-growth-promoting bacteria are already being used successfully on a small scale in several countries, and as this technology matures, the world may witness a major paradigm shift in agricultural practice.

Research on the microbial colonization of the aerial and subterranean tissues of plants has shown an extensive scale of interactions between the hosts and a range of microbes, including bacteria and fungi. Intercellular spaces, vascular systems and even single cells can be inhabited by these endophytic microbes. Of the bacterial endophytes, only a small percentage is harmful to the plant; most are neutral, opportunistic or beneficial. These plant-based bacteria can have various important functions throughout the life cycle of the plant; some promote plant growth and development, others protect the plant from diseases. This ability to be able to protect plants from diseases has catalyzed numerous laboratories to search for new bacteria that could be utilized instead of the traditional plant-protective agents. Because two or more interacting organisms are involved, research and the eventual application of suitable bio-controlling microbes are challenging and often require specific skills and equipment. The purpose of this book is to provide a comprehensive review for those who are interested in the research and biotechnological applications of plant-associated bacteria. It also provides a compilation of current work conducted on plant-bacteria interactions.

With a focus on food safety, this book highlights the importance of microbes in sustainable agriculture. Plants, sessile organisms that are considered as primary producers in the ecosystem and communicate with above- and below-ground communities that consist of microbes, insects, and other vertebrate and invertebrate animals, are subjected to various kinds of stress. Broadly speaking, these can be subdivided into abiotic and biotic stresses. Plants have evolved to develop elaborate mechanisms for coping with and adapting to the environmental stresses. Among other stresses, habitat-imposed biotic stress is one serious condition causing major problems for crop productivity. Most plants employ plant-growth-promoting microorganisms (PGPMs) to combat and protect themselves from stresses and also for better growth. PGPMs are bacteria associated with plant roots and they augment plant productivity and immunity. They are also defined as root-colonizing bacteria that have beneficial effects on plant growth and development. Remarkably, PGPMs including mycorrhizae, rhizobia, and rhizobacteria (Acinetobacter, Agrobacterium, Arthrobacter, Azospirillum, Bacillus, Bradyrhizobium, Frankia, Pseudomonas, Rhizobium, Serratia, Thiobacillus) form associations with plant roots and can promote plant growth by increasing plants’ access to soil minerals and protecting them against pathogens. To combat the pathogens causing different diseases and other biotic stresses, PGPMs produce a higher level of resistance in addition to plants’ indigenous immune systems in the form of induced systemic resistance (ISR). The ISR elicited by PGPMs has suppressed plant diseases caused by a range of pathogens in both the greenhouse and field. As such, the role of these microbes can no longer be ignored for sustainable agriculture. Today, PGPMs are also utilized in the form of bio-fertilizers to increase plant productivity. However, the use of PGPMs requires a precise understanding of the interactions between plants and microbes, between microbes and microbiota, and how biotic factors influence these relationships. Consequently, continued research is needed to develop new approaches to boost the efficiency of PGPMs and to understand the ecological, genetic and biochemical relationships in their habitat. The book focuses on recent research concerning interactions between PGPMs and plants under biotic stress. It addresses key concerns such as – 1. The response of benign microbes that benefit plants under biotic stress 2. The physiological changes incurred in plants under harsh conditions 3. The role of microbial determinants in promoting plant growth under biotic stress The book focuses on a range of aspects related to PGPMs such as their mode of action, priming of plant defence and plant growth in disease challenged crops, multifunctional bio-fertilizers, PGPM-mediated disease suppression, and the effect of PGPMs on secondary metabolites etc. The book will be a valuable asset to researchers and professionals working in the area of microbial-mediated support of plants under biotic stress.

The use of microbial plant protection products is growing and their importance will strongly increase due to political and public pressure. World population is growing and the amount of food needed by 2050 will be double of what is produced now whereas the area of agricultural land is decreasing. We must increase crop yield in a sustainable way. Chemical plant growth promoters must be replaced by microbiological products. Also here, the use of microbial products is growing and their importance will strongly increase. A growing area of agricultural land is salinated. Global warming will increase this process. Plants growth is inhibited by salt or even made impossible and farmers tend to disuse the most salinated lands. Microbes have been very successfully used to alleviate salt stress of plants. Chemical pollution of land can make plant growth difficult and crops grown are often polluted and not suitable for consumption. Microbes have been used to degrade these chemical pollutants.

Plants have evolved both general and highly specialized defence mechanisms that function to prevent diseases caused by the majority of microbial pathogens they encounter. Highly specialized defence is governed by specific interactions between pathogen avr (avirulence) genes' loci and alleles of the corresponding plant disease resistance (R) loci. These defences can be very dynamic as microbes from the same species can act differently in their co-evolution with the specific host plant, which in turn has similarly evolved its response to external threats. There have been major developments in the field of plant-microbe interactions in recent years, due to newly developed techniques and the availability of genomic information. Molecular Plant-Microbe Interactions explores these new discoveries, focusing primarily on the mechanisms controlling plant disease resistance, the cross-talk among the pathways involved and the strategies used by the pathogens to suppress these defences. By exploring developments in plant defences, pathogen's counter-defences and mutually beneficial plant-microbe interactions, this book will be useful for researchers and students in plant pathology and plant biology-related areas.

Der stumme Frühling erschien erstmals 1962. Der Titel bezieht sich auf das eingangs erzählte Märchen von der blühenden Stadt, in der sich eine seltsame, schleichende Seuche ausbreitet … Das spannend geschriebene Sachbuch wirkte bei seinem Erscheinen wie ein Alarmsignal und avancierte rasch zur Bibel der damals entstehendenÖkologie-Bewegung. ZumerstenMal wurde hier in eindringlichem Appell die Fragwürdigkeit des chemischen Pflanzenschutzes dargelegt. An einer Fülle von Tatsachen machte Rachel Carson seine schädlichen Auswirkungen auf die Natur und die Menschen deutlich. Ihre Warnungen haben seither nichts von ihrer Aktualität verloren.
