The very first stage of this process is an exchange of chemical signals between the symbionts. On sensing a flavonoid compound released by the plant, the bacteria produce a signalling molecule known as Nod factor, which is a lipochitooligosaccharide derivative. This molecule in turn induces nodule formation by the plant.<ref>PMID: 18444906</ref><ref>PMID: 17632573</ref><ref>PMID: 1444265</ref> Many types of flavonoids and Nod factors are known and which ones are present influences the specificity of the interaction. It must be mentioned that while these two molecules are important signals and specificity determinants, there are numerous others.<ref>PMID: 20070373</ref><ref>PMID: 18616593</ref> | The very first stage of this process is an exchange of chemical signals between the symbionts.
