FORMATION ACADÉMIQUE

• Stage en microbiologie du sol, 1967 (Institut Pasteur, Paris)
• Ph.D. en biologie forestière, 1966 (Université Laval)
• M.Sc. en botanique, 1964 (Université du Wisconsin)
• B.Sc. en biologie, 1962 (Université Laval)

THÈMES DE RECHERCHE

1. Écophysiologie de la mise à fruit chez les champignons ectomycorhiziens
La démarche vise à comprendre les mécanismes physiologiques, biochimiques et moléculaires impliqués dans le déclenchement et la mise à fruit des basidiomycètes ectomycorhiziens. Rôles des facteurs du milieu et des exsudats racinaires.

2. Rôle comparé des auxines dans le maintien de l'équilibre symbiotique chez les lichens et les ectomycorhizes
Plusieurs hypothèses ont été émises pour expliquer l'équilibre entre symbiontes chez les symbioses végétales. L'étude comparée des lichens et des ectomycorhizes suggère que cet équilibre impliquerait un mécanisme de feedback commun aux deux symbioses et basé sur la synthèse bipartite des auxines permettant de réguler l'exsudation des glucides du partenaire photosynthétique vers le partenaire fongique.

3. Biodiversité de la flore mycorhizienne arbusculaire du Québec
Les outils moléculaires permettent maintenant de classer et d'identifier efficacement les espèces fongiques arbusculaires non seulement sur la base morphologique mais également à l'aide de marqueurs moléculaires. La recherche vise à étudier la floristiques des espèces du Québec en les reliant aux écosystèmes qu'elles habitent. L'accent est mis sur les écosystèmes forestiers d'une sère écologique de la vallée du St-Laurent.

4. Développement de champignons ectomycorhiziens adaptés à divers stress
Pour sélectionner de tels champignons, on peut effectuer des isolations à partir de mycorhizes de plantes provenant de sites où elles sont soumises à ces stress. L'approche que je préconise est basée sur la production de champignons hybrides produits par croisement d'individus haploïdes au laboratoire.

5. Facteurs édaphiques affectant le développement de la phase extra radicale des champignons mycorhiziens arbusculaires sur culture de racine

6. Altération des minéraux par les champignons mycorhiziens et nutrition des arbres.

7. Relations entre les arbres, les champignons ectomycorhiziens et la faune (mycophagie)

RÉALISATIONS RÉCENTES

Avec Caroline Rochon, étudiante au doctorat, nous avons effectué deux études portant sur la biologie, l'écologie et l'aménagement de la dermatose des russules et de la chanterelle dans une forêt de pin gris âgée. Ces études conduites sur le terrain ont permis de relier le développement des fructifications à quelques facteurs écologiques et édaphiques déterminants, notamment la suppression des fructifications de ces espèces, suite à l'épuisement de l'azote; la faible disponibilité en azote favorise l'arrivée de la Kalmia, une plante à mycorhizes éricoïdes compétitives envers les espèces fongiques ectomycorhiziennes. Cette constatation suggère des avenues pour pousser la mycosylviculture de ces espèces.

En équipe (Yves Piché), nous avons obtenu (sept. 2008) une subvention de 3 ans sur la systématique moléculaire des champignons arbusculaires qui permettra d'étudier la biodiversité des champignons arbusculaires des écosystèmes forestiers et autres du Québec.
