Negative or positive feedback between arbuscular mycorrhizal fungi (AMF) and host plants can contribute to plant species interactions, but how this feedback affects plant invasion or resistance to invasion is not well known. Here we tested how alterations in AMF community induced by an invasive plant species generate feedback to the invasive plant itself and affect subsequent interactions betwe...

a greenhouse experiment was conducted to investigate the effects of mycorrhial fungus (glomus mosseae) on cadmium (cd) toxicity in pepper (capsicum annuum l. cv. zhongjiao 105) plants. half of plants were inoculated with arbuscular mycorrhizal fungi (amf). cd was supplied in the form of cadmium chloride at 0.0, 0.1 and 0.5 mm through irrigation water in the soil. mycorrhizal colonization was hi...

The ability of arbuscular mycorrhizal fungi (AMF) to influence the performance of nonnative invasive plants in their introduced range has received increasing attention. The dependence of the invasive nonnative vine pale swallow-wort on AMF was studied in three greenhouse experiments. The aims of the present work were to (1) determine AMF colonization levels of field-collected pale swallow-wort ...

The establishment of the arbuscular mycorrhizal symbiosis results in a modification of the gene expression pattern in both plant and fungus to accomplish the morphological and physiological changes necessary for the bidirectional transfer of nutrients between symbionts. H(+)-ATPase enzymes play a key role establishing the electrochemical gradient required for the transfer of nutrients across th...

Fusarium trichothecenes are fungal toxins that cause disease on infected plants and, more importantly, health problems for humans and animals that consume infected fruits or vegetables. Unfortunately, there are few methods for controlling mycotoxin production by fungal pathogens. In this study, we isolated and characterized sixteen Fusarium strains from naturally infected potato plants in the f...
