Arbuscular mycorrhiza (AM) is a plant-fungal interaction that confers great advantages for the host plant growth. Here we investigated AM phenotypes of AM mutants cerberus and nsp1 and revealed novel regulation mechanisms of AM fungal infection. Transcriptome analysis of these mutants indicated that gibberellin (GA) signaling affects AM fungal infection in the host root. Detailed analysis of GA effect on AM revealed that GA signaling integrated into symbiotic signaling and regulates symbiosis gene expression. We also analyzed RAMI1 that had been isolated as a transcriptional regulator that bind to AM specific cis element. Analysis of RAMI1 indicated that RAMI1 has important roles not only in AM but also in root nodule symbiosis and non-symbiotic physiological functions.

丛枝菌根（AM）是一种植物-真菌相互作用，对宿主植物的生长具有极大的优势。在这里，我们研究了AM突变体cerberus和nsp 1的AM表型，并揭示了AM真菌感染的新调控机制。这些突变体的转录组分析表明，赤霉素（GA）信号影响AM真菌感染的主机根。详细分析GA对AM的影响，发现GA信号整合到共生信号中，调控共生基因的表达。我们还分析了RAMI 1，已被分离作为一个转录调控结合到AM特异性顺式元件。RAMI 1的分析表明，RAMI 1不仅在AM真菌中发挥重要作用，而且在根瘤共生和非共生生理功能中也发挥重要作用。
