Plants face a wide range of environmental challenges, which are expected to become more intense as a result of global climate change. Plant-soil interactions play an important role in the functioning of ecosystems. Soil properties represent a strong selection pressure for plant diversity and influence the structure of plant communities and biodiversity. The complexity of plant-soil interactions has recently been studied by developing a trait-based approach in which responses and effects of plants on soil environment are quantified and modelled. This fundamental research on plant-soil interaction in ecosystems is essential to transpose knowledge of functional ecology to environmental management. Frontiers in Plant-Soil Interaction: Molecular Insights into Plant Adaptation will address topics that provide advances in understanding plant responses to soil conditions through the integration of genetic, molecular, and plant-level studies of diverse biotic and abiotic stresses under field and laboratory conditions. This book will be beneficial to students and researchers working on stress physiology and stress proteins, genomics, proteomics, genetic engineering and other fields of plant-soil interactions. Frontiers in Plant-Soil Interaction will also help scientists explore new horizons in their area of research.
