A genomic sequencing approach to study wood decay and copper tolerance in the brown rot fungus, Antrodia radiculosa
2010 - IRG/WP 10-10720
We used Illumina paired-end short read sequencing (76 nt, 300 bp insert size) to produce a de novo assembly of the genome of Antrodia radiculosa, a copper-tolerant brown rot fungus that is capable of aggressive wood decay. Quality analysis of the base calls in the dataset (8.95 Gb) showed that the majority of the nucleotide sequence was of the highest quality with 5% in the lowest quality group. ...

Gene expression analysis of a copper-tolerant brown rot fungus on MCQ-treated wood
2011 - IRG/WP 11-10748
Most brown rot fungi are copper-tolerant, which makes them difficult to control with copper-based wood preservatives like MCQ. To better understand what biological processes are regulated, we used our model species, Antrodia radiculosa, to examine expression of genes on MCQ-treated wood. Our hypothesis was genes that decreased copper bioavailability would be up-regulated early, when wood showed ...

Analyses of premature failure of utility poles
2012 - IRG/WP 12-40584
In this study a total number of 18 utility poles of Scots pine (Pinus sylvestris) impregnated with a copper-chromium containing preservative were investigated. They were part of different lower voltage transmission lines in the western part of Germany and failed before predicted minimum service life. All poles in this study were less than 15 years in use. The type of decay and fungi were evaluated...

Polyamidoamines (PAA) functionalized with siloxane fragments as potential wood preservatives
2015 - IRG/WP 15-40708
Polyamidoamines (PAAs) utilized in this research were obtained by the reaction between N,N-methyl-bis-acrylamide (MBA) and Ethanolalmine (EtA) and/or aminopropytriethoxysilane (APTES). Different combinations between them were tested as wood preservatives against fungal decay. First, in situ impregnations of PAAs, with the reagents above described in different ratio, were performed and the effectiv...

Use of x-ray microdensitometry for assessing the resistance to the fungus C puteana of a hybrid larches population
2018 - IRG/WP 18-10923
The aim of this research was to utilize the X-ray microdensitometry to determine the natural durability and its variability of a hybrid larch population. The method was applied on slices obtained by increment cores collected on standing trees before cutting them down. The methodology was discussed also in order to propose as a new screening method especially suited for trees populations. X-ray mic...
