The diversity of mtDNA rns introns among strains of Ophiostoma piliferum, Ophiostoma pluriannulatum and related species
BACKGROUND Based on previous studies, it was suspected that the mitochondrial rns gene within the Ophiostomatales is rich in introns. This study focused on a collection of strains representing Ophiostoma piliferum, Ophiostoma pluriannulatum and related species that cause blue-stain; these fungi colonize the sapwood of trees and impart a dark stain. This reduces the value of the lumber. The goal...
متن کاملPhylogeny and taxonomy of the Ophiostoma piceae complex and the Dutch elm disease fungi
The Ophiostoma piceae complex forms a monophyletic group of insect-dispersed pyrenomycetes with synnemata (Pesotum) and micronematous (Sporothrix) synanamorphs. Other species of Ophiostoma outside of the 0. piceae complex that form synnemata lack the Sporothrix state. The nine recognized species within the 0. piceae complex are delimited by synnema morphology, growth rate at 32 C, mating reacti...
متن کاملFurther studies on mutant strains of Ophiostoma which require guanine.
Biochemical mutants which require guanine but are unable to utilize adenine and hypoxanthine obviously represent a very rare type of purine deficiency in microorganisms. So far, guanineless mutations have been observed only in the ascomycet,ous fungus, Ophiostoma multiannulatum, in which seven strains of this biochemical type were isolated after x-ray or ultraviolet irradiation (l-3). Three of ...
متن کاملAlbino Strains of Ophiostoma Species for Biological Control of Sapstaining Fungi
New Zealand produces large diameter radiata pine (Pinus radiata) in short rotations, making it the dominant species used in its forest products industry. As with other fast growing pine species, radiata pine produces wood that consists primarily of sapwood, and is susceptible to dark discolorations due to sapstaining fungi. As a result, significant losses are incurred by the New Zealand forest ...
متن کاملRapid detection of Ophiostoma piceae and O. quercus in stained wood by PCR.
A rapid, sensitive, and simple method was developed to detect the sapstain fungi Ophiostoma piceae and O. quercus in stained wood. By using microwave heating for DNA extraction and PCR with internal transcribed spacer-derived-specific primers, detection was feasible within 4 h, even with DNA obtained from a single synnema. This method can easily be extended for the detection of other wood-inhab...
