We report here that the pea early nodulin genes PsENOD5 and PsENOD12A are induced during the interaction of pea roots and the endomycorrhizal fungus Gigaspora margarita. Using the pea nodulation mutant Sparkle-R25, which is mutated in SYM8, it is shown that SYM8 is essential for the induction of PsENOD5 and PsENOD12Ain pea roots interacting either with Rhizobium or the endomycorrhizal fungus Gigaspora margarita. Our results suggest that mycorrhizal signals activate a signal transduction cascade sharing at least one common step with the Nod factor-activated signal transduction cascade.
我们在此报告，豌豆早期结瘤素基因PsENOD5和PsENOD12A在豌豆根与丛枝菌根真菌珠状巨孢囊霉相互作用期间被诱导。使用在SYM8中发生突变的豌豆结瘤突变体Sparkle-R25，结果表明SYM8对于在与根瘤菌或丛枝菌根真菌珠状巨孢囊霉相互作用的豌豆根中诱导PsENOD5和PsENOD12A至关重要。我们的结果表明，菌根信号激活了一个信号转导级联，该级联与Nod因子激活的信号转导级联至少共享一个共同步骤。
