Researchers demonstrate that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size. Researchers ...

Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors ...

Legume plants do not depend on externally supplied nitrogen, because they can form a symbiosis with nitrogen-fixing bacteria, called rhizobia. The plants recognize the nitrogen-fixing bacteria and ...

The processes that govern the formation of symbiotic structures between nitrogen-fixing bacteria and legumes in the latter's roots remain largely a mystery to science, but researchers have recently ...
