Recent Advances in the Molecular Genetics of The Model Legume Lotus japonicus
Abstract
In an attempt to accelerate the progress in understanding the plant contribution to symbiotic nitrogen fixation, the model legume Lotus japonicus was suggested as experimental organism for a focused international venture (Handberg and Stougaard, 1992). At the Laboratory of Gene Expression the main emphasis has been concentrated on the molecular genetics of root nodule organogenesis, together with the signal transduction and the transcriptional gene regulation occurring during root nodule development. Different approaches aimed at developing the molecular genetic techniques applicable to L. japonicus has been initiated and some of the progress will be reported here. The approaches taken to establish transposon tagging using the maize elements Ac and Ds were presented recently (Thykjær et al. 1995, Pajuelo et al. 1996). This proceeding will therefore concentrate on presenting some of the other methodologies under investigation or in use.
