Root exudation consists of several biochemicals which act as the modifier of rhizospheric ecosystem favouring plant growth and development. These biochemicals play a role of signals to call the beneficial microbes towards plant root and deterring the pathogenic species away from the rhizosphere due to which they are also described as “Infochemicals”. Flavonoids are one of the most important infochemicals exudated from various plant roots that help in regulating rhizospheric nutrient status, microbial diversity and biotic and abiotic adaptation etc. owing to their importance and prominence in rhizospheric signalling, they have been studied for their chemistry and mode of action in exudation which resulted in collection of important information related to their synthesis and diversity in plant system as well as their actions in the rhizosphere which are helpful for plants to develop and adapt very stressful …
