The equilibrium: hæmoglobin ⇄ methæmoglobin in the root nodules depends decisively on the intensity of light and on the stage of growth of the plants. The root nodules of vigorously growing ...

Root nodules are organs on plant roots that facilitate the symbiotic relationship. Rhizobia colonize these nodules and fix nitrogen by converting nitrogen from air into ammonia. Iron is needed for ...

These factors are broadly conserved in plants, indicating their nodule-specifying function in legumes is a more recent innovation. This significant discovery brings us one step closer to ...

The key to their success is a type of bacteria called rhizobia, which lives inside nodules, or the little nubs you sometimes see on plant roots. While we usually think of bacteria as dangerous ...
