- ... Nodule-specific (nodulin) genes are thought to play crucial roles during establishment of the nitrogen-fixing symbiosis between legume plants and Rhizobium bacteria. On the basis of a gene expression database for early stages of the nodulation process of Lotus japonicus, previously constructed by a cDNA macroarray analysis, we identified a novel nodulin gene, LjnsRING, which encodes a protein with ...

- ... Symbiotic nitrogen fixation (SNF) in legume nodules is a highly energy demanding process, fuelled by plant-supplied carbohydrates mainly in the form of sucrose. In this study, we have combined molecular and biochemical approaches in order to study the spatial and temporal organisation of sucrose metabolism in nitrogen-fixing nodules of the model legume Lotus japonicus, with an emphasis on the negl ...

- ... Legume plants develop specialized root organs, the nodules, through a symbiotic interaction with rhizobia. The developmental process of nodulation is triggered by the bacterial microsymbiont but regulated systemically by the host legume plants. Using ethylmethane sulfonate mutagenesis as a tool to identify plant genes involved in symbiotic nodule development, we have isolated and analyzed five nod ...
