This book focuses on the importance and roles of seed microbiomes in sustainable agriculture by exploring the diversity of microbes vectored on and within seeds of both cultivated and non-cultivated plants. It provides essential insights into how seeds can be adapted to enhance microbiome vectoring, how damaged seed microbiomes can be assembled again and how seed microbiomes can be conserved. Plant seeds carry not only embryos and nutrients to fuel early seedling growth, but also microbes that modulate development, soil nutrient acquisition, and defense against pathogens and other stressors. Many of these microbes (bacteria and fungi) become endophytic, entering into the tissues of plants, and typically exist within plants without inducing negative effects. Although they have been reported in all plants examined to date, the extent to which plants rely on seed vectored microbiomes to enhance seedling competitiveness and survival is largely unappreciated. How microbes function to increase the fitness of seedlings is also little understood. The book is a unique and important resource for researchers and students in microbial ecology and biotechnology. Further, it appeals to applied academic and industrial agriculturists interested in increasing crop health and yield.

Most plants are colonized by endophytes: bacterial and fungal microorganisms, without visible disease symptoms. With state-of-the-art knowledge on their discovery, qualities and roles, this book describes endophyte diversity, their value, exploitation and future challenges. It explains how beneficial endophytes colonize plants, and how they might help mitigate climate change effects, assist pest control and interact with mycorrhizal fungi to boost yield. Endophytes can facilitate the access to nutrients, produce particular metabolites, and change the plant's chemistry, physiology and (defense) responses. Endophyte biosynthetic pathways can, alone or in combination with the plant's, yield novel chemicals, with yet-to-be-discovered pharmacological characteristics as well. The book describes how functional metagenomics can explore and boost yields of useful endophyte products.

Endophytes are commonly known as microorganisms, mainly bacteria and fungi, which live inside plant tissues without inducing symptoms. Considering the long-lived trees, endophytes have a fundamental role in preparing their hosts to face extreme weather conditions, drought, heat, cold, and pathogen and herbivore attacks. The current knowledge clearly demonstrates the importance of endophytes in shaping the plant diversity in a forest. Endophytes have an important capacity for biocontrol of forest diseases. Considering endophyte diversity and the range of various compounds and enzymes they can produce, endophytes can be used for various biotechnological applications.

Plants are typically colonized by numerous endophyte species symbiotically without any noticeable disease symptoms. These microbes are abundant, diverse and play critical ecological roles across natural and agricultural ecosystems. Endophytes have attracted the attention of researchers due to their various beneficial effects on plants, especially in agricultural crop species. Genomic tools will enhance our understanding on the growth and nutrition requirements of this host-symbiont relationship. Recent advances in DNA sequencing technologies and bioinformatic pipelines have allowed analyzing the plant microbiome and host-endophyte interaction more effectively with limited bias. Furthermore, various studies have employed and utilized transcriptomic and genomic tools to understand the role of endophytes and their interaction with plant hosts. This electronic book covers various research articles highlighting the important developments on endophytes using transcriptomics, next generation sequencing and genomic tools.

Endophytes are the plant symbionts that live inside the plant tissue without causing any symptoms of disease for a part of their life-cycle, as compared to the rhizosphere and phyllosphere microbes that live on the plant’s surface, and pathogens that cause disease. Bacteria and fungi are the two most common groups that are included in endophytes. They find their way into plants’ endosphere to become extremely important plant symbionts that improve metabolite profile, fitness and stress tolerance of the host. Endophytes are an important untapped reservoir of biological resources. During the last few decades, endophytes have attracted scientists working in the field of agriculture, environment and industry due to the possibilities of diverse biotechnological applications in such fields. Endophytes promote plant growth by improving the physiological and metabolic functions of the host plants via nutrient acquisition, nitrogen fixation, phytohormone production, enhancing abiotic/biotic stress tolerance, and disease resistance. These benefits conferred by the endophytes can be used to promote agriculture yield and food quality. In addition endophytes are known to produce novel antibiotics; secondary metabolites including alkaloids, flavonoids, steroids, phenolic acids, quinines; siderophores; and enzymes such as chitinases and cellulases. These natural compounds have use in pharmaceutical, food and agricultural industries. Endophytes have usage in biodegradation, bioextraction or bioaccumulation of environmental pollutants. They also have potential application in enhanced phytoremediation. More recently, endophytic bacteria and fungi have also been used for the green synthesis of nanoparticles for different medical and industrial applications. Functional genomics studies of endophytes provided more information and better understanding of network of the complex host-endophyte interactions and other associated microbes to harness the biotechnological potential of endophytes more efficiently and sustainably.

Plants create a dynamic micro-biosphere in the soil, around the roots, called as ‘rhizosphere’, which harbors diverse number of microorganisms for sustaining their growth and development. A soil with diverse and multi-traits microbial communities is considered healthy to enhance crop productivity. In the last decades, rhizosphere biology has gained attention due to unraveling of new mechanisms, processes and molecules in the rhizosphere that contributes towards the promotion of plant productivity. The rhizospheric microbes and associated processes are being utilized for harnessing potential of soils in effective and sustainable functioning in the agro-ecosystems. Broadly, the book discusses rhizospheric microbes and their role in modulating functions of soil and crop plant. Specifically, it highlights conventional and modern aspects of rhizosphere microbes such as – microbiome in the rhizosphere, microbes as an indicator and promoter of soil health, rhizosphere microbes as biofertilizer, biostimulator and biofortifyer, microbial signaling in the rhizosphere, recent tools in deciphering rhizobiome, and regulatory mechanisms for commercialization of biofertilizer, biopesticide and biostimulator. The book is useful for agriculture scientist, biotechnologist, plant pathologist, mycologist, and microbiologist, farming community, scientist of R&D organization, as well as teaching community, researcher and student and policy maker.

This book aims to present an alternative based on natural processes and an environmental approach to post-excavation site management, e.g., post-coal mining heaps. These sites are places where various mineral excavation by-products are collected. Nevertheless, some post-mineral excavation sites are oligotrophic, terrestrial, wetland, and water habitat islands, providing unique biodiversity enrichment in the landscape. These oligotrophic mineral habitats are essential in over-fertilized, eutrophic, agricultural and urban-industry surroundings. Some post-mineral excavation sites are places where the wildlife can develop and support the functional processes of novel ecosystems. Implementing the newest biogeochemical and comprehensive knowledge into urban-industry landscape management will help to establish the ecosystem’s processes and environmental functioning. There are several post-industrial sites in Europe where the wildlife areas developed due to natural processes, are becoming wildlife hotspots in densely populated urban-industry areas. In this respect, many of the oligotrophic mineral terrestrial, wetland, and water habitats of anthropogenic origin should not be categorized as environmentally dangerous and undergo economic utility-focused reclamation. Facing the actual environmental constraints of the Anthropocene Epoch, the book’s chapters presenting the natural basics and perquisites of the environmental ecosystem mosaics, will be interesting for a broad range of environmentalists (scientists and students), miners, economists, and sociologists.
