Secondary Metabolites of Plant Growth Promoting Rhizomicroorganisms by Harikesh Bahadur Singh,Chetan Keswani,M. S. Reddy,Estibaliz Sansinenea,Carlos García-Estrada Pdf

Recent changes in the pattern of agricultural practices from use of hazardous pesticides to natural (organic) cultivation has brought into focus the use of agriculturally important microorganisms for carrying out analogous functions. The reputation of plant growth promoting rhizomicroorganisms (PGPRs) is due to their antagonistic mechanisms against most of the fungal and bacterial phytopathogens. The biocontrol potential of agriculturally important microorganisms is mostly attributed to their bioactive secondary metabolites. However, low shelf life of many potential agriculturally important microorganisms impairs their use in agriculture and adoption by farmers. The focal theme of this book is to highlight the potential of employing biosynthesized secondary metabolites (SMs) from agriculturally important microorganisms for management of notorious phytopathogens, as a substitute of the currently available whole organism formulations and also as alternatives to hazardous synthetic pesticides. Accordingly, we have incorporated a comprehensive rundown of sections which particularly examine the SMs synthesized, secreted and induced by various agriculturally important microorganisms and their applications in agriculture. Section 1 includes discussion on biosynthesized antimicrobial secondary metabolites from fungal biocontrol agents. This section will cover the various issues such as development of formulation of secondary metabolites, genomic basis of metabolic diversity, metabolomic profiling of fungal biocontrol agents, novel classes of antimicrobial peptides. The section 1 will also cover the role of these secondary metabolites in antagonist-host interaction and application of biosynthesized antimicrobial secondary metabolites for management of plant diseases. Section 2 will discuss the biosynthesized secondary metabolites from bacterial PGPRs, strain dependent effects on plant metabolome profile, bio-prospecting various isolates of bacterial PGPRs for potential secondary metabolites and non-target effects of PGPR on microbial community structure and functions. Section 3 encompasses synthesis of antimicrobial secondary metabolites from beneficial endophytes, bio-prospecting medicinal and aromatic hosts and effect of endophytic SMs on plants under biotic and biotic stress conditions.

Antifungal Metabolites of Rhizobacteria for Sustainable Agriculture by R.Z Sayyed,Anjana Singh,Noshiin Ilyas Pdf

Antifungal Metabolites of Rhizobacteria for Sustainable Agriculture focuses on plant health in agro-ecosystems of various economically important cash and food crops with a concern to promote sustainable agriculture. They have emerged as a key organic tool for enhancing yields. In a natural environment the interactions between plants and phytopathogenic fungi are complex and survival requires a development of resistance to plant diseases. Diversity of Plant Growth Promoting Rhizobacteria (PGPR) diversity depends on the nature of root exudates and soil conditions that affect their interaction with host plants. Novel strategies, such as, applying bioactive natural products against the pathogenic fungus are required to control disease sustainably. Various classes of secondary metabolites including lipopeptides, macrolides, alkaloids, terpenoids and phenolics from microorganisms and plants strongly suppress fungal growth and can also be effective in controlling plant diseases both in vitro and in vivo. The modes of actions of some potential antifungal secondary metabolites against pathogenic fungus are also discussed. Eco-friendly fungal species and their metabolites are excellent agents used for regulating various fungal and bacterial phytopathogens and may have tremendous potential for other applications, and play a key role in enhancing plant tolerance to stress. Antifungal Metabolites of Rhizobacteria for Sustainable Agriculture also covers bovine-based formulations used for sustainable production and nutritional security through horticultural crops, thereby addressing the problems associated with malnutrition and under-nutrition encountered by small and marginal farmers, as well as by families facing resource constraints. These techniques can also improve breathable air, drinkable water, and consumable foods. This book addresses the need to mitigate the health problems of people via organic crop production and to improve the socio-economic status of farmers (especially in developing countries), and to revitalize agricultural sustainability.

Microbial-mediated Induced Systemic Resistance in Plants by Devendra K. Choudhary,Ajit Varma Pdf

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.
