Fast moves in arbuscular mycorrhizal symbiotic signalling.
Exciting research looking at early events in arbuscular mycorrhizal symbioses has shown how the fungus and plant get together. Kohki Akiyama et al. have demonstrated that strigolactones in root exudates are fungal germ tube branching factors, and Arnaud Besserer et al. found that these compounds rapidly induce fungal mitochondrial activity. Andrea Genre et al. have shown that subsequent development of appressoria on host roots induces construction of a transient prepenetration apparatus inside epidermal cells that is reminiscent of nodulation infection.
