Abstract

Plant stress through global warming may be counteracted by the application of tropical or subtropical organisms. Pleurotus pulmonarius is an edible mesophilic wood-decay mushroom which additionally can promote plant growth. The potential of alleviating plant stress has been tested in vitro in this study using a subtropical strain from Taiwan. The attraction and toxicity against the nematode Caenorhabditis elegans proven here experimentally on a quantitative base indicate the potential to decrease the impact of plant-parasitic nematodes. A weak antifungal ability against Fusarium oxysporum and Lasiodiplodia hormozganensis was observed in vitro dual cultures. Through oxide (CaO and ZnO) solubilization by P. pulmonarius demonstrated here, the fungus may influence chemico-physical soil properties. The combination of these capabilities of P. pulmonarius may provide opportunities for its prospect applications in agriculture to alleviate biotic and abiotic stress conditions and enhance plant growth in the future.
