Endophytic fungal community structure in olive orchards with high and low incidence of olive anthracnose

Abstract Fungal endophytes have been increasingly recognized to promote host plant protection to pathogens, but knowledge of the multiple effects that they could have in crop diseases is still scarce. This work attempts to understand the role of fungal endophytes in crop diseases, specifically in re...
