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，拟南芥的波浪状初生根比直根产生更多的侧根，然后，通过使用含有蛭石和结冷胶固化的培养基作为根发育培养基，我们成功地从柿子品种和芒果幼苗的微插条产生的不定根中诱导出侧根。该根系发育培养基还改善了低生根能力的日本梨品种和芒果幼苗的微插条的生根。为了分析侧根的遗传组成，我们产生了侧根多和侧根少的拟南芥突变株。
