Research Abstract

Plant secondary metabolites released from the roots are involved in the chemical communications between plants and other organisms in the rhizosphere. In particular, unstable and short-lived compounds have been focused in these rhizosphere communications, as these compounds have not been detected adequately in most motabolome studies on these chemical communications. Hence, we examined roles of unstable plant metabolites including strigolactones (SLs) on one of the unexplained chemical communications in the soil, self/non-self and kin recognitions of root system. In wild-type and max1 mutant of Arabidopsis, number of branches increased significantly and the roots grew in bundles when they were grown on the medium from which ammonium nitrogen had been removed. These results indicate that SLs may be involved in self/non-self and kin recognitions of root system in Arabidopsis.
