“…Anderson and Stasovski (1992) compared sequences of the intergenic region (IGR) of rDNA to assess the phylogeny of Armillaria. Isozyme analysis (Morrison, 1982;Morrison et al, 1985a) and immunological techniques (Lung-Escarment et al, 1985) were successful in differentiating among some groups within the genus Armillaria. Characteristics of basidiome morphology have also been used to differentiate among closely related species Dessureault, 1988, 1989).…”

“…Separation of biological species of Armillaria can also be possible by biochemical means through the analysis of isozyme profiles (MORRISON et al 1985;GUILLAUMIN et al 1983;HUTTERMANN et al 1983). …”

Three groups of morphologically distinct isolates were observed among nine Kenyan Armillaria isolates based on their mycelium and rhizomorphs characteristics. Seven of the isolates were interfertile with testers of North American biological species III, VII and IX. However, tests with benomyl segregants BEN 433, BEN 157-10 and BEN AVK were intersterile with the same testers and also with the European A. mellea, A. lutea and A. ostoyae. The analysis of isozyme profiles showed that morphologically similar isolates had similar isozyme profiles of esterases. Their profiles however differed from those of the European yl. mellea, A. lutea and/I. ostoyae. On the basis of intersterility tests and analysis of isozyme profiles, the Kenyan isolates should be considered different.

“…Within Armillaria spp., Morrison et al (1985b) were able to distinguish among six Armillaria ISGs occurring in British Columbia by isoelectric focusing of their esterases and of polyphenol oxidase. These enzymes should not be considered as neutral or independent markers because of their possible role in pathogenicity.…”

The need for a rapid and definite diagnosis of the Armillaria spp. and Heterohasidion annosum root and butt rot diseases as well as general requirements expected of a test to detect the pathogens are reviewed. As a spin-off from more fundamental molecular biological research there has been a remarkable increase in new methods for diagnosis (i.e. detection and identification) in recent years. These new methods all have in comtnon that they use strtjctural elements of the target organisms such as proteins, polysaccharides, glycoproteins, nucleic acids, etc. for the construction of antibodies, probes and primers for detection, or to produce electrophoretic patterns to be used for classification and identification. This paper presents a short review of principles, advantages, disadvantages and some perspectives of the new methods developed for Armillaria spp. and H. annosum diagnosis compared with conventional ones, such as interfertility testing or visual inspection of the pathogens in situ and in vitro in pure culture. It will be noted that the specificity and reproducibility of the new techniques, which are closely linked with potential experimental error, lead to principal pitfalls which should be kept in mind when conclusions are drawn on data generated by them.Even though PCR-based methods become increasingly more widespread it is likely that most diagnostic methods will continue to be used or co-exist in some form in the future.
