Genetic diversity and morphometric study of thirteen populations of Microcerotermes diversus (Silvestri)(Isoptera: Termitidae) in southern Iran
2012 - IRG/WP 12-10782
Microcerotermes diversus (Silvestri) (Isoptera: Termitidae), an important wood pest in Iran, causes serious economic damage to cellulosic products in buildings. To investigate the genetic diversity of this pest, 13 populations from different areas of Khuzestan province as well as two samples from Khârg Island and Bandar Abbas were collected. After DNA extraction, a fragment with 486 bp length fro...

The effects of acetylation level on the growth of Postia placenta over 36 weeks
2012 - IRG/WP 12-40589
Genomic sequencing gives us a tool to systematically and rapidly discover novel genes, how their products function in the cell, and explore their interactions. When the DNA sequences are known, primers can be designed to detect transcripts of genes with gene products related to basic cellular processes and hyphal growth. The characteristic gene products induced in different fungi by different wood...

Extraction and analysis of DNA from green and seasoned timber as basic methods for determination of wood species and origin
2013 - IRG/WP 13-20523
Against the background of the European timber trade regulation EUTR, commenced to law by March 2013, the determination of wood species and tracing of its origin is getting a great importance. A promising approach for establishing fast and reliable tracking systems for wood products is DNA analysis. A critical point is the extraction of analysable DNA from the wood and its lignified cell walls. Thu...

What molecular biology can tell us about the biodegradation of lignocellulose: the utilization of molecular techniques for the detection, identification and enhanced understanding of wood degrading organisms
2013 - IRG/WP 13-20528
Molecular techniques are now routinely used in the identification, detection and analysis of wood degrading organisms. An overview of some of the early work on nucleic acid isolation and characterization will be followed by a discussion of the power of sequencing and other procedures for better understanding: the mechanisms involved in the biological degradation of wood, the metabolic basis of pre...

Postia placenta cellulase gene expression in modified wood during incipient decay
2013 - IRG/WP 13-40626
In optimization of modified wood, it is important to understand the mode of action of the wood modification and how the fungi response to it. The aim of this study was to investigate the expression of cellulases during the first two weeks of Postia placenta exposure in acetylated, DMDHEU-treated and thermally modified as well as in untreated wood. Using real-time PCR, the gene expression patterns ...

Communities of mold fungi in moisture damaged building materials
2014 - IRG/WP 14-20542
The critical conditions needed for the development of mould and decay fungi have been modelled for different building materials. However, current knowledge of indoor microbes growing on building materials relies on culture-based methods and more advanced molecular biological techniques should be employed to study the complex microbial communities in building materials. In this paper molecular biol...

Real-Time PCR Assays for the detection of the dry rot fungus Serpula lacrymans and its close relative Serpula himantioides
2016 - IRG/WP 16-10867
Prevention of wood decay by fungi of the phylum Basidiomycota is an important issue of wood protection. The most destructive fungus in buildings in Central Europe is the dry rot fungus Serpula lacrymans, which needs more extensive restauration measures than all other wood decay fungi. Its close relative S. himantioides occurs more frequently in outdoor environment. The assessment and remediation o...
