Direct evidence for a variable barrier to diffusion into legume nodules



Direct evidence for a variable barrier to diffusion into legume nodules



Nitrogen fixation research progress: 355



The nature of the variable barrier to O2 diffusion in nodules of peas and Phaseolus vulgaris was studied using micro-electrodes. Within functional nodules of both spp. the oxygen concn sensed by the electrode in the bacteroid-containing region was <1 micro M.
