Illustration of coumarin- and microbiota-dependent plant iron nutrition

Caption

In iron-limiting soils, plants activate an iron-deficiency response that includes production and secretion of coumarins. These compounds alter the composition of the root microbiota and elicit a microbial activity that rescues plant iron nutrition, improving plant growth.
