Abstract excerpt
The ndvA and ndvB genes of Rhizobium meliloti are involved in the export and synthesis, respectively, of the small cyclic polysaccharide beta(1,2)glucan. We have previously shown that spontaneous symbiotic pseudorevertants of ndv mutants do not produce periplasmic beta(1,2)glucan. Here we show that the pseudorevertants also do not produce extracellular beta(1,2)glucan, but do show alterations in the amount of the...
