Binding of isolated plant lectin by rhizobia during episodes of reduced gravity obtained by parabolic flight

摘要: Development of a legume root nodule is complex process culminating in plant/bacterial symbiosis possessing the capacity for biological dinitrogen fixation. Formation nodules initiated by binding and stabilization rhizobia to plant hairs, mediated part receptor/ligand recognition system composed lectins on surface lectin-binding sites rhizobial cell surface. The fixation activity these may be an important feature enclosed, space-based life support systems, provide ecological method recycle nitrogen amino acid production. However, effects development varied gravitational fields, or nutrient delivery hardware, remain unknown. We have investigated microgravity formation, with preliminary experiments focused upon component. Microgravity, obtained during parabolic flight aboard NASA 930, has no apparent effect purified lectin rhizobia, result that will facilitate forthcoming using intact tissues.
