This book describes the multitude of interactions between plants, soil, and microorganisms. It emphasizes how growth and development in plants, starting from seed germination, is heavily influenced by the soil type. It describes the interactions established by plants with soil and the inhabitant microbial community. The chapters describe how plants selectively promote certain microorganisms in the rhizospheric ecozone to derive multifarious benefits such as nutrient acquisition and protection from diseases. The diversity of these rhizospheric microbes and their interactions with plants largely depends on plant genotype, soils attributes, and several abiotic and biotic factors.
Most of the studies concerned with plant-microbe interaction are focused on temperate regions, even though the tropical ecosystems are more diverse and need more attention. Therefore, it is crucial to understand how soil type and climatic conditions influence the plant-soil–microbes interaction in the tropics. Considering the significance of the subject, the present volume is designed to cover the most relevant aspects of rhizospheric microbial interactions in tropical ecosystems.
Chapters include aspects related to the diversity of rhizospheric microbes, as well as modern tools and techniques to assess the rhizospheric microbiomes and their functional roles. Plant, Soil and Microbes in Tropical Ecosystems also covers applications of rhizospheric microbes and evaluation of prospects improving agricultural practice and productivity through the use of microbiome technologies.
