%X In the course of the symbiotic interaction between Rhizobium meliloti, R. leguminosarum bv. viciae and their host plants, the plant exudate can induce rhizobia produce extracellular molecules, i. e. the nod factors which cause some morphological, physiological and genetic changes in the roots of host plants. The Nod factors can be detected by the Had assay which is based on the root hair morphological changes. The result of Had assay demonstrats that at the presence of plant seed exudates, R. huakuii could produce Nod factor and its bio-activity is to elicit the root hair helix-curling.
