Dark Septate Endophytes (DSE) in Boreal and Subarctic Forests

Part of the Forestry Sciences book series (FOSC, volume 86)

Abstract

Dark septate endophytes (DSE) are root-associated fungi that inhabit plant roots and soil in a wide variety of ecosystems and host plants worldwide. They are recognized by their distinctive growth habit inside healthy roots, although the taxonomic and functional variety of the fungi forming the associations is high. DSE fungi have the potential to act as beneficial symbionts of the trees and other plants, but the evidence is unequivocal. They grow in the roots together with mycorrhizal- and other root-associated fungi, but the relationships between these fungal groups are unknown. Boreal and subarctic forests constitute a continuous belt in the cool and cold areas of the Northern Hemisphere. Roughly, boreal forests are characterized by coniferous trees. The subarctic is most distinctive in the Northernmost Europe where mountain birch (Betula pubescens ssp. czerepanovii) forests form a continuous forest cover near the Arctic treeline. In this chapter, information from studies on DSE fungi in the boreal and subarctic forests is compiled and discussed.
