Bacteria produce a wide range of exopolysaccharides which are synthesized via different
biosynthesis pathways. The genes responsible for synthesis are often clustered within the …

Nitrogen-fixing rhizobial bacteria and leguminous plants have evolved complex signal
exchange mechanisms that allow a specific bacterial species to induce its host plant to form …

Rhizobium meliloti Rm1021 must be able to synthesize succinoglycan in order to invade
successfully the nodules which it elicits on alfalfa and to establish an effective nitrogen-fixing …

Specific complex interactions between soil bacteria belonging to Rhizobium, Sinorhizobium,
Mesorhizobium, Phylorhizobium, Bradyrhizobium and Azorhizobium commonly known as …

Rhizobia are soil proteobacteria able to engage in a nitrogen-fixing symbiotic interaction
with legumes that involves the rhizobial infection of roots and the bacterial invasion of new …

Publisher Summary This chapter provides an overview of the molecular mechanisms
involved in synthesis and expression of cell-surface polysaccharides in Gram-negative …

The 8x0 genes of Rhizobium meliloti are needed for thesynthesisof an acidic
exopoiysaccharide, succinogiycan. We have assigned biosynthetic roles to the products of …

Rhizobia are Gram-negative bacteria that can exist either as free-living bacteria or as
nitrogen-fixing symbionts inside root nodules of leguminous plants. The composition of the …

The major acidic exopolysaccharide of Rhizobium meliloti, termed succinoglycan, is
required for nodule invasion and possibly nodule development. Succinoglycan is a polymer …

12, 15 11, 23-26 substituent. Succinylation requires ExoH, while pyruvylation requites ExoV.
Non-acetylated or non-succinylated succinoglycan can still be polymerized and exported …
