Induction of root cortical cell divisions by heterologous nodulation factorsple, . biovar viciae nodulates pea and vetch, but not clover, soybean or alfalfa, whereas . biovar trifolii preferably nodulates clover. Key factors in mutual recognition of the symbiotic partners are lipochitin oligosaccharides (LCOs), produced by the rhizobia. Expression of host-plant-specificity

expression precedes cell division and affects phytohormone perception at the onset of nodulationcontrolled manner (Van Brussel et al., 1992; Vijn et al., 1993). In most temperature legumes like pea and alfalfa, cell division is induced in the inner cortex opposite proto-xylem points (Libbenga and Harkes, 1973; Newcomb et al., 1979). Although the mode of action of Nod factors remains unresolved

-Acyl Galactosamine Inhibition of Lipo- Chitooligosaccharide Actionormation of nodules on the roots of leguminous plants (Dénarié and Cullimore, 1993). The important role of LCOs as plant growth regulators has stimulated considerable interest in their synthesis. Therefore, we developed simplified procedures for the synthesis of LCOs which employ both an enzymatic a

Cell Cycle Regulation during Nodule Developmentochemical pathways, called checkpoints [11], have evolved to ensure that the initiation of particular programmes is dependent upon the successful completion of others thereby coordinating cell cycle transitions. In mammalian cells the cell cycle transitions are controlled by extracellular and intrac

The Saga of the Nodulin Genesn in soybean root nodules .. Following this, a group of other nodulins were detected using various immunological approaches and 2-D gel analysis. and nodulin-35 was characterized to be a subunit of the nodule-specific uricase.. These early studies, coupled with DNA sequence hybridization. and differ
