Taxonomic position of Gremmeniella abietina and related species: a reappraisal

Abstract: A comparative study of isolates and their corresponding herbarium specimens of Gremmeniella spp. from pine, spruce, and balsam fir, of Ascocalyx laricina from larch, and of Ascocalyx abietis from balsam fir was conducted using morphological and cultural characteristics as well as electrophoresis tests on 12 and 10 – 15% gradient polyacrylamide gels. In addition, the conidia and the ascospores of the specimens were treated with 4′,6-diamino-2-phenylindole to determine the number of nuclei per cell. Ascocalyx ab… Show more

“…1989). Later,thèse three races were confirmed as being divergent based on their ecological, etiological and molecular characteristics, but are considered morphologically indistinguishable (Bernier et al 1994;Hamelin et al 1993;Petrini et al 1989Petrini et al , 1990. The NA and EU races are présent in North America while the Asian race has only been reported in Japan.…”

“…Morelet var. abietina (Petrini et al 1989) is the causal agent of Scleroderris canker in conifers of Fennoscandia. Although the sexual stage of G. abietina was described from Norway spruce growing naturally (Lagerberg 1913), Scleroderris canker has periodically destroyed lot of Scots pine seedlings in nurseries.…”

“…Sur la base de tests sérologiques, le champignon capable d'envahir la cime de grands arbres a été qualifié de race européenne (EU), alors que celui ne causant des dommages qu'à moins de 2 m de hauteur a été nommé race nord-américaine (NA) sur ce continent et race asiatique au Japon (Dorworth et Krywienczyk 1975). Par la suite, cette séparation en différentes races a été précisée et confirmée par de nouvelles méthodes d'identification (Bernier et al 1994;Hamelin et al 1993Hamelin et al , 1996Petrini et al 1989). Au Canada, c'est au Québec en 1978 que la race EU du G. abietina a été identifiée pour la première fois (Lachance 1979).…”

“…Le diagnostic se faisait sur le terrain. Les races (sérovar) du G. abietina ont été identifiées par la méthode de protéines solubles (Petrini et al 1989). Deux chancres montrant la coloration jaune-verdâtre typique du chancre scléroderrien ont été échan-tillonnés en 1983.…”
