Abstract:
Exudates of a dark septate endophyte (DSE) identified as Dreschlera sp, a common
endophyte isolated by the inner cortical cells of the grass Lolium multiflorum, were put
in contact with the arbuscular mycorrhizal fungus (AMF) Gigaspora rosea. These
exudates stimulated the hyphal length and the hyphal branching of the AMF. A negative
effect on the extramatrical phase of the AMF was detected. This is the first report to
show how exudates of DSE can affect the development of AMF. These results show
that DSE could be modifying the mycorrhizal status of the plants, modulating a
different symbiosis in the rhizosphere.
