Disease relevance of nodL

By using a gain-of-function approach, we showed that the presence of nodL, and hence of O-acetylated Nod factors, is a major prerequisite for confering the ability to nodulate alfalfa upon the heterologous bacterium Rhizobium tropici [1].

High impact information on nodL

In contrast, double nodF/nodL mutants were unable to penetrate into legume hosts and to form ITs [2].
The first gene of this operon is identical to the nodL gene identified by Baev and Kondorosi (1992) in R. meliloti strain AK631 [1].
In addition, it was shown that the nodM and nodN genes are in one operon which is preceded by a conserved 'nod-box' sequence, whereas the nodL gene is in the same operon as the nodFE genes [3].
Nucleotide sequence of the Rhizobium meliloti nodL gene located in locus n5 of the nod regulon [4].
