Research Abstract |
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.
