Research Abstract |
Phenotype of LjPAP3 knockdown in Lotus japonicus was evaluated to elucidate the molecular mechanism of phosphate transport in arbuscular mycorrhiza. The knockdown plants were defective in phosphate uptake. Arbuscular mycorrhizal fungi colonized in the knockdown plants had much more polyphosphate than in the wild-type plants. These results suggested that LjPAP3 is involved in phosphate transport via mycorrhizal symbiosis. Polyphosphate polymerases of arbuscular mycorrhizal fungus were identified: VTC1, VTC2 and VTC4. The VTC4 generated polyphosphate from ATP.
