Mycorrhizas are symbioses between fungi and the roots of higher plants. As more than 90% of all known species of plants have the potential to form mycorrhizal associations, the productivity and species composition and the diversity of natural ecosystems are frequently dependent upon the pre sence and activity of mycorrhizas. The biotechnological application of mycorrhizas is expected to promote the production of food while maintaining ecologically and economically sustainable production systems.




Unveiling the Mycorrhizal World


Book Description

Mycorrhizal fungi are widespread organisms found in various regions across the globe that are closely related to a broad range of root plant species, including agricultural crops. These fungi exhibit multiple traits that promote plant growth, and numerous studies have demonstrated their ability to increase plant growth by improving the availability and efficiency of nutrient and water uptake from the soil. Specifically, mycorrhizal fungi have been shown to increase the availability of nitrogen and phosphorus in plants. While these fungi cannot fix nitrogen from the atmosphere, they are capable of mineralizing organic matter, releasing nitrogen that is trapped in molecules and cellular organelles. In addition, arbuscular mycorrhizal fungi (AMF) can increase phosphorus availability in plants. However, high levels of phosphorus in the soil can decrease the interactions between the fungus and the host plant. Some studies have shown that mycorrhizal fungi can enhance plant tolerance to environmental stress. In summary, mycorrhizal fungi can be used to promote plant growth, improve nutrient utilization efficiency, reduce environmental impacts and production costs, and enhance plant tolerance to cope with stress conditions. The use of AMF is an excellent strategy to achieve sustainable production.




Agriculturally Important Fungi for Sustainable Agriculture


Book Description

Microbes are ubiquitous in nature. Among microbes, fungal communities play an important role in agriculture, the environment, and medicine. Vast fungal diversity has been found in plant systems. The fungi associated with any plant system are in the form of epiphytic, endophytic, and rhizospheric fungi. These associated fungi play important roles in plant growth, crop yield, and soil health. The rhizospheric fungi present in rhizospheric zones have a sufficient amount of nutrients released by plant root systems in the form of root exudates for growth, development, and activities of microbes. Endophytic fungi enter in host plants mainly through wounds that naturally occur as a result of plant growth, or develop through root hairs and at epidermal conjunctions. The phyllospheric fungi may survive or proliferate on leaves, depending on the extent of influences of material in leaf diffuseness or exudates. The diverse group of fungal communities is a key component of soil-plant systems, where they are engaged in an intense network of interactions in the rhizospheric, endophytic, and phyllospheric areas, and they have emerged as an important and promising tool for sustainable agriculture. These fungal communities help to promote plant growth directly or indirectly by mechanisms for plant growth-promoting (PGP) attributes. These PGP fungi can be used as biofertilizers, bioinoculants, and biocontrol agents in place of chemical fertilizers and pesticides in an environmentally and eco-friendly manner. This book covers the current knowledge of plant-associated fungi and their potential biotechnological applications in agriculture and allied sectors. This book should be useful to scientists, researchers, and students of microbiology, biotechnology, agriculture, molecular biology, environmental biology, and related subjects.

Plant Ecophysiology and Adaptation under Climate Change: Mechanisms and Perspectives II


Book Description

This book presents the state-of-the-art in plant ecophysiology. With a particular focus on adaptation to a changing environment, it discusses ecophysiology and adaptive mechanisms of plants under climate change. Over the centuries, the incidence of various abiotic stresses such as salinity, drought, extreme temperatures, atmospheric pollution, metal toxicity due to climate change have regularly affected plants and, and some estimates suggest that environmental stresses may reduce the crop yield by up to 70%. This in turn adversely affects the food security. As sessile organisms, plants are frequently exposed to various environmental adversities. As such, both plant physiology and plant ecophysiology begin with the study of responses to the environment. Provides essential insights, this book can be used for courses such as Plant Physiology, Environmental Science, Crop Production and Agricultural Botany. Volume 2 provides up-to-date information on the impact of climate change on plants, the general consequences and plant responses to various environmental stresses.




Advances in Plant Microbiome and Sustainable Agriculture


Book Description

Microbes are ubiquitous in nature, and plant-microbe interactions are a key strategy for colonizing diverse habitats. The plant microbiome (epiphytic, endophytic and rhizospheric) plays an important role in plant growth and development and soil health. Further, rhizospheric soil is a valuable natural resource, hosting hotspots of microbes, and is vital in the maintenance of global nutrient balance and ecosystem function. The term endophytic microbes refers to those microorganisms that colonize the interior the plants. The phyllosphere is a common niche for synergism between microbes and plants and includes the leaf surface. The diverse group of microbes are key components of soil-plant systems, and where they are engaged in an extensive network of interactions in the rhizosphere/endophytic/phyllospheric they have emerged as an important and promising tool for sustainable agriculture. Plant microbiomes help to directly or indirectly promote plant growth using plant growth promoting attributes, and could potentially be used as biofertilizers/bioinoculants in place of chemical fertilizers. This book allows readers to gain an understanding of microbial diversity associated with plant systems and their role in plant growth, and soil health.

The Role of Nanoparticles in Plant Nutrition under Soil Pollution


Book Description

Nanotechnology has shown great potential in all spheres of life. With the increasing pressure to meet the food demands of rapidly increasing population, thus, novel innovation and research are required in agriculture. The principles of nanotechnology can be implemented to meet the challenges faced by agricultural demands. Major challenges include the loss of nutrients in the soil and nutrient-deficient plants, which result in a lower crop yield and quality. Subsequently, consumption of such crops leads to malnourishment in humans, especially in underprivileged and rural populations. One convenient approach to tackle nutrient deficiency in plants is via the use of fertilizers; however, this method suffers from lower uptake efficiency in plants. Another approach to combat nutrient deficiency in humans is via the use of supplements and diet modifications; however, these approaches are less affordably viable in economically challenged communities and in rural areas. Therefore, the use of nano-fertilizers to combat this problem holds the greatest potential. Additionally, nanotechnology can be used to meet other challenges in agriculture including enhancing crop yield, protection from insect pests and animals, and by use of nano-pesticides and nano-biosensors to carry out the remediation of polluted soils. The future use of nanomaterials in soil ecosystems will be influenced by their capability to interact with soil constituents and the route of nanoparticles into the environment includes both natural and anthropogenic sources. The last decade has provided increasing research on the impact and use of nanoparticles in plants, animals, microbes, and soils, and yet these studies often lacked data involving the impact of nanoparticles on biotic and abiotic stress factors. This book provides significant recent research on the use of nano-fertilizers, which can have a major impact on components of an ecosystem. This work should provide a basis to further study these potential key areas in order to achieve sustainable and safe application of nanoparticles in agriculture.
