Fungal root endophytes ofQuercus robursubjected to flooding

Summary In August 2011, fungal endophytes were isolated from fine (0.1–0.5 cm diameter) and structural (0.6–2.0 cm) roots from eighteen Q. robur trees at six sites in a Q. robur‐dominated forest displaying symptoms of oak decline. Five sites were subjected to periodic flooding for 3 months in 1997 and 1 month in 2010. Fungal colonization was detected in 94% of 1296 root fragments examined. Fungi representing 126 taxa from Zygomycota (four species), Ascomycota (117 species) and Basidiomycota (five species) were isolated using culture‐based methods and identified by morphotyping and sequencing of the ITS 1 and 2 rDNA. The most frequent eudominants (with colonization frequencies ≥10%) were Aspergillus spp., Cosmospora sp., Ilyonectria radicicola, Pezicula radicicola, Pyrenochaeta cava and six species of Trichoderma. Species composition did not vary greatly between sites, but only 3% of species occurred in all sites. Number of species was higher in roots subjected to floods. Eudominants and dominants present only on flooded sites included Aspergillus spp., Chaetomium globosum, Cosmospora sp., I. radicicola, Sporothrix inflata, Trichoderma harzianum, T. pubescens and T. virens. Structural roots were usually colonized by a higher number of species than fine roots. The majority of species detected belong to Class 2 NC‐endophytes. Pezicula radicicola and Phialocephala fortinii belong to Class 4 NC‐endophytes.

“…In this study, S. inflata was generally recorded at high frequency from roots of young pines. According to Halmschlager and Kowalski (2003), this fungus can occur in healthy oak roots as an endophyte. (Halmschlager and Kowalski 2003) and P. abies seedlings (Menkis et al 2006) have been low.…”

Root‐colonizing ophiostomatoid fungi associated with dying and dead young Scots pine in Poland

et al. 2012

Ophiostomatoid fungi are carried by various bark beetles. However, very little is known about the role of these fungi in conifer roots. We studied ophiostomatoid fungi in roots of dying and dead Pinus sylvestris trees and tested the potential phytotoxicity of some isolates using a sensitive bioassay with Lepidium sativum in Poland. Fungi were identified based on their morphology and DNA sequencing. Three ophiostomatoid fungi, Leptographium procerum, Sporothrix inflata and Ophiostoma pallidulum, were isolated from the roots. The most abundant soil-borne fungus, S. inflata, and relatively rare O. pallidulum were isolated for the first time from roots of dying and dead pine trees. The frequency of S. inflata and O. pallidulum correlated with tree decline. The fungi were isolated more frequently from roots of dead than dying trees. Sporothrix inflata and O. pallidulum slightly reduced the stem and root growth of L. sativum. Leptographium procerum reduced more significantly root than stem growth. This species reduced root elongation 32-54% after 10-17 days of incubation.
