Using DNA probes to characterize the metabolic pathway of pigment production in several wood-staining fungi
1996 - IRG/WP 96-10146
During shipment and storage, lumber is susceptible to sapstain, a wood discoloration caused by fungi. Currently kiln drying and chemical applications are used to control sapstain. However, the chemicals used to protect wood have a broad range of action, and so can affect other organisms. In addition, in Canada most of these chemicals are under temporary registration. Thus there is a need to develo...

Isolation of a gene from the melanin pathway of the sapstaining fungi Ophiostoma piceae using PCR
1997 - IRG/WP 97-10219
To prevent sapstaining fungi from discoloring wood, it is necessary to determine what factors affect the biosynthesis and characteristics of the pigment(s) and to identify the genes involved in the pathway. Using inhibitors and heterologous DNA probes from Alternaria alternata, we suggest that melanin, the pigment of Ophiostoma piceae, is produced by the dihydroxynaphthalene (DHN) pathway. Recentl...
