Bacteriorhiza

⭐
feminine noun (biology / botany / agronomy)

Definition

A stable symbiotic association formed between the roots of higher plants and certain soil bacteria, particularly nitrogen-fixing ones (such as Rhizobium species). Physiologically, this ecological structure allows plants (especially legumes) to assimilate atmospheric nitrogen transformed by bacteria into accessible compounds, while the microorganisms receive carbohydrates derived from photosynthesis.
