摘要

Autoregulation of nodulation (AON) is the mechanism that systemically controls the number of nodules per plant through communication between the shoot and the root of leguminous plants, using unknown signal molecules other than photosynthate (Ito et al. 2006a, b). The hypernodulation soybean mutant lines form profuse nodulation compared with their parent, most likely because they either lack or have decreased activity of a part of AON. AON in soybean (Glycine max [L.] Merr.) is controlled by a CLAVATA1 (CLVl)-like receptor kinase, GmNARK (Searle et al., 2003). However, the actual role of GmNARK in AON has not yet been clarified. The details of the growth characteristics of hypernodulation mutant lines may be important to understanding AON. Herein, the plant-growth characteristics of soybean hypernodulation mutants, NOD1-3, NOD2-4 and NOD3-7, were compared with their parent cv. Williams. Although the mutation site(s) have not been reported, evidence (Vuong et al., 1996; Vuong and Harper, 2000; Nishimura et al., 2002) suggests that the mutated locus of all NOD mutant lines is in GmNARK. The phenotypes of hypernodulation mutant lines showed other plant- growth features and, generally, show less vigorous growth than the parents.
