Fungicide effects on fungal community composition in the wheat phyllosphere.

Karlsson I, Friberg H, Steinberg C, Persson P - PLoS ONE (2014)

Bottom Line: This study examined fungicide effects on fungal communities on winter wheat leaves in two areas of Sweden.It was found that commonly used fungicides had moderate but significant effect on fungal community composition in the wheat phyllosphere.The relative abundance of several saprotrophs was altered by fungicide use, while the effect on common wheat pathogens was mixed.

ABSTRACT
The fungicides used to control diseases in cereal production can have adverse effects on non-target fungi, with possible consequences for plant health and productivity. This study examined fungicide effects on fungal communities on winter wheat leaves in two areas of Sweden. High-throughput 454 sequencing of the fungal ITS2 region yielded 235 operational taxonomic units (OTUs) at the species level from the 18 fields studied. It was found that commonly used fungicides had moderate but significant effect on fungal community composition in the wheat phyllosphere. The relative abundance of several saprotrophs was altered by fungicide use, while the effect on common wheat pathogens was mixed. The fungal community on wheat leaves consisted mainly of basidiomycete yeasts, saprotrophic ascomycetes and plant pathogens. A core set of six fungal OTUs representing saprotrophic species was identified. These were present across all fields, although overall the difference in OTU richness was large between the two areas studied.

Fungal community composition on wheat leaves at the order level.Community composition is presented for the total dataset, fungicide-treated, control and samples from the Northern and Southern area respectively. Orders with low abundance have been merged to the group ‘Others’ to improve visual representation.

pone-0111786-g003: Fungal community composition on wheat leaves at the order level.Community composition is presented for the total dataset, fungicide-treated, control and samples from the Northern and Southern area respectively. Orders with low abundance have been merged to the group ‘Others’ to improve visual representation.

Mentions: The fungal community in the present study consisted of almost equal proportions of ascomycetes (54%) and basidiomycetes (46%). The most common orders in the dataset were Sporidiobolales, Tremellales, Capnodiales and Pleosporales (Fig. 3).
