Abstract
The rhizosphere, a microecosystem, harbours numerous organisms such as bacteria, fungi, actinomycetes, and nematodes. The definite and diverse community that can grow or survive in the rhizosphere is called rhizomicrobiome. The community and activity of microorganisms could be enhanced and decided by the respective plants by the special molecules called root exudates. The plant root exudates facilitate molecular communication in and from root to root and root to microorganisms. The exudates not only attract the microorganisms, but also suppress the growth of unfavorable microbes. The plant exudates have been facilitated to establish the relationship with the plant’s root system as mutualism or antagonism or neutralism. These roots release molecules that play a vital role in communication and maintain the microbial community in the rhizosphere. For example, some molecules are also involved in bioremediation process by absorption of heavy metals. Overall, this chapter concentrates on transport and release of plant root exudates into rhizosphere and how the exudates influence the specific and diversified microbial growth and their adaptation in microecosystem of rhizosphere.
