| Research Abstract |
The aim of this study is to identify arbuscular mycorrhizal (AM) fungal metabolites that act as the symbiotic signal “myc factor” in the AM symbiosis. We identified chitin tetramer to octamer as an inducer of symbiotic responses in the roots of model legume Lotus japonicus. Myc-LCOs (AM fungi-derived lipochitooligosaccharides) reported as myc factor by Maillet et al. (2011) were chemo-enzymatically synthesized. It was found that Myc-LCO and chitin oligomers respectively induce symbiotic responses via NFR-dependent and -independent pathways.
