Lipo-chitooligosaccharides (LCO's) have been known for some time as the Nod factors that are released by nitrogen-fixing Rhizobia and are essential for their capacity to induce nodules on leguminous plants. The structure of these LCO's was solved by Lerouge in 1990 (P. Lerouge et al., ...
while legumes also associate with nitrogen-fixing rhizobial bacteria. Both associations rely on symbiosis signaling and here we show that cereals can perceive lipochitooligosaccharides (LCOs) for activation of symbiosis signaling, surprisingly including Nod factors produced by nitrogen-fixing bacteria. Howev...

Lipochitooligosaccharides (LCO) or Nod factors, which are rhizobia-produced signal molecules, induce deformation of legume root hairs. In addition to triggering legume plant nodulation, Nod factors influence cell division and promote somatic embryo generation in non-legume plants. This suggested to us...
The solution conformation of two lipooligosaccharides related to Nod factors or lipochitoligosaccharides have been analysed by 1D and 2D 1 H and 13 C NMR spectroscopy, molecular mechanics and dynamics calculations. The obtained data indicate that the glycosidic torsion angles have restricted fluctuations...
The products of the nod genes are Nod factors, which have been identified as lipo-chitooligosaccharides (LCO) (Long, 1996).

Treatment of the transgenic rice roots with Nod factors (10 –6 –10 –9 m ) under nitrogen‐limiting conditions induced MtENOD12 ‐GUS expression in cortical parenchyma, endodermis and pericycle. In contrast, chitooligosaccharide backbone alone failed to elicit such a response in the root tissues...
These factors play a pivotal role in the molecular signal exchange, infection and induction of symbiotic developmental responses in legumes leading to the formation of a nodule in which rhizobia carry out N2 fixation. Determining whether rice (Oryza sativa) can respond to Nod factors could lead to...
Nod factorsnodulationpeptidoglycanSummary Chitin is the second most abundant polysaccharide in nature, found in crustacean shells, insect exoskeletons and fungal cell walls. The action of chitin and chitin derivatives on plants has become a very interesting story of late. Chitin is a β1-4-linked ...
