      Moreover, different parts of the root release different chemical compounds into the soil, such as meristem, the root elongation zone exudes asparagine and threonine, the root hair zone releases various hydrophobic and hydrophilic amino acids, including phenylalanine, leucine, valine, and glutamic acid, aspartic acid excretes from all parts of the root zone, and the root tip secretes mucilage (Badri and Vivanco 2009). Root exudates characteristics and amounts get changed according to plant genotype, age, biotic, and abiotic stress state, health and disease conditions of the plant, the surface area of the root system, and root architecture (Badri and Vivanco 2009). Apart from the plant characteristics, the environmental factors also show an impact on the root exudation mechanism and exudate constituents (Canarini et al. 2019). Thus, understanding the mechanism of root exudation, and factors affecting it, is of prime importance to support environmentally sustainable agriculture and to alleviate the large use of agricultural chemicals that create biosphere contaminations.

Schematic illustration of the classification of root exudates compounds: various compounds are found in the root exudation, which belongs to wide array of biochemical classes.

      Root exudates exploration revealed the high diversity of chemicals in plant root exudates. Exudation profiling revealed the presence of chemical compounds, and explains the function of concerning chemical in the soil ecosystem and their effects on plant systems. Few technologies, such as NMR and MS, narrate the structural characters of exudate compounds for clearer observations and assist in unravelling the properties of these compounds that are present in root exudates (Verma et al. 2018). Thus, these studies are directed to the chemical synthesis of those compounds, which can be further utilized for conditioning the soil for particular crop cultivation and for paving a way toward “rhizosphere engineering” (Bais et al. 2006). Root exudates profiling may prove to be the strongest technique for elaborating on the root role and overcomes the plant‐ and soil‐ related issues that hinders crop productivity and sustainable agriculture.
