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.

植物根系释放的次生代谢产物参与了植物与根际其他生物的化学通讯。特别是，不稳定和短寿命的化合物一直集中在这些根际通信，因为这些化合物没有被充分检测到在大多数代谢组研究这些化学通信。因此，我们研究了不稳定的植物代谢产物，包括独脚金内酯（SL）的作用在土壤中的一个原因不明的化学通讯，自我/非自我和亲属的根系。拟南芥野生型和max 1突变体在去除铵态氮的培养基上生长时，分枝数显著增加，根成束生长。这些结果表明，SL可能参与了拟南芥根系的自/非自分化和亲缘分化。
