Sucrose synthase (SS) activity has been suggested to be a key point of regulation in nodule
metabolism since this enzyme is down‐regulated in response to different stresses which …

Most N2‐fixing prokaryotes are free‐living organisms or grow in association with various
plant or fungal species, but some have evolved to form symbioses with the relatively small …

Recent research has shown that nodule nitrogen fixation is limited under a wide range of
