The plant microbiomes (rhizospheric, endophytic and epiphytic) play an important role in plant growth, development, and soil health. Plant and rhizospheric soil are a valuable natural resource harbouring hotspots of microbes, and it plays critical roles in the maintenance of global nutrient balance and ecosystem function. The diverse group of microbes is key components of soil–plant systems, where they are engaged in an intense network of interactions in the rhizosphere/endophytic/phyllospheric. The rhizospheric microbial diversity present in rhizospheric zones has a sufficient amount of nutrients release by plant root systems in form of root exudates for growth, development and activities of microbes. The endophytic microbes are referred to those microorganisms, which colonize in the interior of the plant parts, viz root, stem or seeds without causing any harmful effect on host plant. Endophytic microbes enter in host plants mainly through wounds, naturally occurring as a result of plant growth, or through root hairs and at epidermal conjunctions. Endophytes may be transmitted either vertically (directly from parent to offspring) or horizontally (among individuals). The phyllosphere is a common niche for synergism between microbes and plant. The leaf surface has been termed as phyllosphere and zone of leaves inhabited by microorganisms as phyllosphere. The plant part, especially leaves, is exposed to dust and air currents resulting in the establishments of typical flora on their surface aided by the cuticles, waxes and appendages, which help in the anchorage of microorganisms. The phyllospheric microbes may survive or proliferate on leaves depending on extent of influences of material in leaf diffuseness or exudates. The leaf diffuseness contains the principal nutrients factors (amino acids, glucose, fructose and sucrose), and such specialized habitats may provide niche for nitrogen fixation and secretions of substances capable of promoting the growth of plants. The microbes associated with plant as rhizospheric, endophytic and epiphytic with plant growth promoting (PGP) attributes have emerged as an important and promising tool for sustainable agriculture. PGP microbes promote plant growth directly or indirectly, either by releasing plant growth regulators; solubilization of phosphorus, potassium and zinc; biological nitrogen fixation or by producing siderophore, ammonia, HCN and other secondary metabolites which are antagonistic against pathogenic microbes. The PGP microbes belong to different phylum of archaea (Euryarchaeota); bacteria (Acidobacteria, Actinobacteria, Bacteroidetes, Deinococcus-Thermus, Firmicutes and Proteobacteria) and fungi (Ascomycota and Basidiomycota), which include different genera namely Achromobacter, Arthrobacter, Aspergillus, Azospirillum, Azotobacter, Bacillus, Beijerinckia, Burkholderia, Enterobacter, Erwinia, Flavobacterium, Gluconoacetobacter, Haloarcula, Herbaspirillum, Methylobacterium, Paenibacillus, Pantoea, Penicillium, Piriformospora, Planomonospora, Pseudomonas, Rhizobium, Serratia and Streptomyces. These PGP microbes could be used as biofertilizers/bioinoculants at place of chemical fertilizers for sustainable agriculture. The aim of “Plant Microbiomes for Sustainable Agriculture” is to provide the current developments in the understanding of microbial diversity associated with plant systems in the form of rhizospheric, endophytic and epiphytic. The book is useful to scientist, research and students related to microbiology, biotechnology, agriculture, molecular biology, environmental biology and related subjects.

Microbiomes from plants, soil and extreme environments are naturally gifted with amazing capabilities which play significant roles in the maintenance of global nutrient balance and ecosystem functions. The microbiomes from diverse niches have in fact emerged as potential tools for improving the plant growth and productivity by diverse mechanisms include solubilization of nutrients, nitrogen fixation, hormonal stimulation as well as biotic and abiotic stress tolerance. Further, these microbiomes have an immense potential to maintain soil health and fertility. Thus, dependent on their mode of action and effects, these microbiomes can be used as biofertilizers, biopesticides, plant strengtheners, and phytostimulators whic...

The plant-endophyte association ranges from mutualism to pathogenicity. Endophytic microbes help the host to combat diverse arrays of both biotic and abiotic stressful conditions. Endophytic microbes play a major role in growth enhancement of their host, solubilization of macronutrients such as phosphorous, potassium, and zinc, fixation of atmospheric nitrogen, synthesis of phytohormones, siderophores, hydrogen cyanide, ammonia, and act as a biocontrol agent against wide array of phytopathogens etc. Endophytic microbes are beneficial to plant by directly promoting their growth or indirectly by inhibiting the growth of phytopathogens. Over a long period of co-evolution endophytic microbes have attained the mechanism of synthesis of various hydrolytic enzymes such as pectinase, xylanases, cellulase, proteinase etc. which promote the penetration of endophytic microbes into tissues of plants. The enzymes are very specific in their action on substrate and play different roles, such as convert macromolecule into small one as well as toxic substance into less toxic. The effective usages of endophytic microbes in the form of biofertilizers reduce the usage of chemical fertilizers. Endophytic microbes belong to different phyla such as Actinobacteria, Acidobacteria, Bacteroidetes, Deinococcus-thermus, Firmicutes, Proteobacteria, and Verrucomicrobia. The most predominant and studied endophytic bacteria belonged to Proteobacteria followed by Firmicutes and then by Actinobacteria. The most dominant among reported genera in most of the leguminous and non-leguminous plants are Bacillus, Pseudomonas, Fusarium, Burkholderia, Rhizobium, and Klebsiella. In future, for the sustainable agriculture, endophytic microbes have a wide range of potential for maintaining health of plant as well as environmental conditions. The present review is focused on the research being done on endophytic microbes including their diversity in leguminous as well as non-leguminous crops, biotechnological applications, and ability to promote the growth of plant

The term secondary metabo-lites was first introduced by Albrecht Kossel in 1891 (Mothes, 1980; Hartmann, 2007). He was awarded with a Nobel Prize for physiology or medicine in 1910. It is understood that these secondary metabolites play a significant role in the adaptation of plants to its environment; some of the functions of secondary metabolites are attraction of pol-linators, protection against pests and diseases, etc. (Wink, 1988). They also provide an important source of effective pharmaceutical products. At the end of the 1960s, plant cell culture technologies were introduced as possible tools for the study and production of secondary plant metabolites. Several strategies have been considerably studied using in vitro systems to improve the production of secondary plants compounds (Bourgaud et al., 2001). A target of both the agrochemical and the pharmaceutical industry is the development of new biologically active secondary metabo-lites (Höller et al., 2000). Over the last five decades, studies on plant secondary metabolites (SM) have increased. Some microbes are also known to develop secondary metabolites that may be involved in a host-endophyte relationship. Other microbes and fungal secondary metabolites, that is, SM from fungi are also promising compounds that play several roles in different industries. Secondary metabolites produced by fungal endophytes are identified as pharmaceutically useful crops (Aly et al., 2010). Numerous bioactive metabolites, known as new substances, have recently been identified with a broad range of biological activities including antibiotics, antioxidant, antitumor and inflammatory; the microbes like endophytes can be very useful as medicinally effective agents for biotechnological development of bioactive substances. In addition, examples of selected compounds of endophytic fungal secondary metabolites obtained from terrestrial and mangrove plants have been published in 2008-09. These compounds have been selected according to their properties such as antimicrobial, neuroprotective, cytotoxic, antiparasitic, etc. The growing interest of public in secondary metabolites has led to the drug discovery research that includes biochemical , biosynthesis, metabolic, pharmacological, mycological, and molecular techniques from higher medicinal fungi. Several new secondary metabolites have been isolated from higher fungal communities and will most likely lead to the discovery of new drugs that include chemopreventive agents possessing the bioactivity of anticancer drug, immu-nomodulatory, etc. Besides the application of fungal secondary metabolites, numerous challenges are faced by secondary metabolites screened from higher fungi, such as biosynthetic metabolites, identification, bioseparation, and model screening (Yadav et al., 2016, 2017). Secondary metabolites screened from fungi have a limited number of commercial products as compared to plants because of less information about fungal secondary metabolites. Trichoderma spp., the commercially available plant growth promoting fungus (PGPF), is used for the enhancement of plant and is also used as a biocontrol agent. This popular genera of fungi is extensively used in the agricultural field and in industry (Keswani et al., 2014).

But now a day’s level of micronutrients has been declined and even some has been vanished from the food crops because farmers chose to grow more productivity of the crops and make more profits. The reduced amount of micronutrients in food crops causing micronutrient deficiencies or hidden hunger in human, which is one of the serious global threats that affect more than two million people worldwide. Hidden hunger can cause dangerous health conditions and diseases such as birth defect, cancer, cardiovascular disease, osteoporosis, neurodegenerative disorders and many more. To overcome these issue microbes mediated biofortification is a new and promising option for the bioavailibity of nutrient to plants. Biofortification is getting more attention to incraese phytoavialbility of micronutrients easpecially Fe, Zn, Mg, Se in the major food crops. Utilization of diverse types of microbes that promotes plant growth is becoming effective approach to substitute synthetic fertilizers, pesticides, and supplements. Microbes mobilize the nutrients by various mechanisms such as acidification, chelation, exchange reactions, and release of organic acids.
