Since there are a lot of similarity
in nodule development between Rhizobia exposed to nano-particles and
LPS mutant Rhizobia, it is necessary to further examine the biochemical
structure, molecular properties and outer membrane stability of the
Rhizobia and the bacteroids that were exposed to nano-particles, especially,
the unique very-long-chain fatty acid (VLCFA) and the O-chain
polysaccharide in lipid A of LPS.
