ABSTRACT
The constant and sometimes uncontrolled use of pesticides and the dispersion of inorganic and organic pollutants in environment imbalance the soil ecosystem, hence reducing soil fertility and land use. In this context, it becomes crucial to develop innovative agrobiotechnological approaches to optimize the use of soils in agriculture and restoring marginal and degraded lands. Bio-phytoremediation represents an eco-friendly and low- cost microbe- or plant-based approach to remove contaminants from environment using physiological processes of living organisms as bacteria or plants. However, promising bioremediation approaches are still limited due to the essential lack of detailed knowledge of the biological systems (the overall biotic community and its mutual relationships) present in the soil. To optimize bioremediation as a robust commercial technology, more knowledge is needed on biotic interactions taking place in the soil, especially in relation to the microbiome. Here, I discuss an integrative system biology approach which can be applied to decipher and predict microbiome and plant-microbiome relationships in soil and its application to phytoremediation. In particular, the present chapter deals with goal, potentials, and outcomes of "omics tools" to understand the deep insights into the comprehension of plant-host interrelationship and the mechanism involved in the enhancement of pollutants remediation.
