We had shown that waving primary roots of Arabidopsis thaliana produced more lateral roots than straight roots, and then, by using vermiculite-containing and gellan gum-solidified medium as a root development medium, we were successful in inducing lateral roots from adventitious roots produced from microcuttings of kaki cultivars and mango seedlings. The root development medium also improved rooting of the microcuttings of Japanese pear cultivars of low-rooting-ability and mango seedlings. To analyze the genetic makeup of lateral roots, we produced mutated strains of Arabidopsis thaliana having many lateral roots and few lateral roots.

我们已经证明，拟南芥的主要根部与直根产生更多的侧根，然后通过使用含虫的含有ver虫和胶质胶溶解的培养基作为根发育培养基，我们成功地从而诱导了由不良根诱导的横向根部。 Kaki品种和芒果幼苗的微裂料。根发育培养基还改善了低根和芒果幼苗的日本梨品种的微切植物的生根。为了分析侧根的遗传构成，我们产生了具有许多侧根和较少侧根的拟南芥的突变菌株。
