Cambridge scientists have identified two crucial genetic factors needed to produce specialized root organs that can accommodate nitrogen-fixing bacteria in legumes such as peas and beans. In a ...
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 ...
Legume–rhizobia symbiosis enables the development of root nodules that fix nitrogen for plant use and for the terrestrial nitrogen cycle 1. To date, early signalling perception and transduction, ...
Legume-rhizobia root-nodule symbioses involve the recognition of rhizobial Nod factor (NF) signals by NF receptors, triggering both nodule organogenesis and rhizobial infection. RinRK1 is induced by ...
Recent research on Lotus japonicus, a model leguminous plant, has unveiled that the interaction between legume roots and rhizobia is characterized by periodic gene expression with a six-hour rhythm.
The developmental regulators that confer the identity of N-fixing root nodules belong to a transcription factor family (LSH) more commonly associated with defining the shapes of stems, flowers and ...
