	Flavonoid phytoalexins (antimicrobial and antioxidative substances) are activated in the case of an attempted breach of root tissue by an undesired outsider [3] These phytoalexins protect the root system from pathogens, undesirable bacteria, and even [[insects]] from interfering and harming their structures and/or growth space. These chemicals can be kept in dormant reserve for quick deployment if the need arises in the future. In terms of defense from pathogens, a flavonol called quercetin has been shown to repel attacks from ''E. coli'' by impeding ATPase activity (conversion of ATP to ADP resulting in a release of energy).

	Flavonoids have also been found to cause [[allelopathy]], the release of chemicals that deter other plants from growing near the host plant. This can be a huge problem for agriculture in the case of an invasive plant species. This is exactly the case in some sub-Saharan African farm plots. The invasive weed ''Striga'' kills off any surrounding crop planted by farmers and can cause up to a 100% loss in crop yield.

	Flavonoids aid in the interaction of plant roots with microorganisms in the surrounding area. [3] [[Plant roots]] can exude these chemicals through decomposing root caps and border cells. Once in the soil, flavonoids act as reducing agents and metal chelators towards metals. This increases the number of nutrients, particularly iron and phosphorous, available to the nearby plant roots.

	Flavonoids are also key in the formation of nodules. Nodules are stores of fixed nitrogen created through a symbiotic relationship between plant roots and rhizobium bacteria. [6] Flavonoids improves transcription of nod genes by making access to RNA polymerase easier for the nodule to form. Conversely, nodule formation can be suppressed in order to maintain optimal conditions for the rate of nodule formation to remain unchanged.		Flavonoids are also key in the formation of nodules.
