Functional analysis of corn husk photosynthesis.

abstract：:The relative efficiency (RE) of N(2) fixation (RE = 1 - [H(2) evolved in air]/[acetylene reduced]) was investigated in a Rhizobium strain lacking uptake hydrogenase activity (Hup(-)). Variation in RE of such strains presumably reflects changes in the electron allocation coefficient of nitrogenase. By artificially exte...
