Induction of root cortical cell divisions by heterologous nodulation factors
Conference paper
Abstract
The symbiotic interaction between rhizobia and legume plants, resulting in formation of nitrogen-fixing root nodules, is host-plant-specific. For example, Rhizobium leguminosarum biovar viciae nodulates pea and vetch, but not clover, soybean or alfalfa, whereas R. leguminosarum 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 is a two-step process: host plant-derived flavonoids can specifically induce production of LCOs by rhizobia, and LCOs can specifically induce root nodule formation in host plant roots.
