Nodulation-defective rhizobia and their nodule-forming derivatives containing cloned DNA from the wild type were used to study nodulation suppression in Phaseolus vulgaris L. Non-nitrogen-fixing derivatives which formed rhizobia-containing white nodules induced partial suppression. Comparison of this with the complete suppression by Fix derivatives and a Fix mutant which formed rhizobia-containing pink nodules suggests that the extent of suppression may be related to successive stages of nodule development.

根瘤缺陷型根瘤菌及其含有从野生型克隆 DNA 的形成根瘤的衍生物被用来研究菜豆的结瘤抑制。不固氮的衍生物形成含有根瘤的白色根瘤，诱导部分抑制。与 Fix 衍生物和形成含有根瘤的粉红色根瘤的 Fix 突变体的完全抑制相比，这表明抑制的程度可能与根瘤发育的连续阶段有关。
