Laboratory of Forest Functional Biology

We focus on functional aspect of forest organisms through physiological, chemical, structural and genetic researches at levels of individual, organ, tissue, cell, gene and compound expressed against various biotic and abiotic agents in diverse field environment. We try to reveal mechanisms of interaction among these agents. Such information can be applied for protection, improvement and sustainable use of forest.

Our research topics include how trees respond against pathogen attack, and how the environment and symbiotic microorganisms affect the defense system of trees. These topics are studied in terms of the interaction of trees with other forest organisms, microorganisms, in particular. In the area of environmental stress, the tolerance of trees to heavy metals and water stress has been evaluated. This information can be used for reforestation of deserted mines contaminated with heavy metals as well as improvement of tree health in urban area.

Major theme

  • Defense responses and resistance mechanisms of trees against pathogens and their application to forest health.
  • Mechanism of blockage of water conduction in wilt disease of trees and determinants of pathogenesis
  • Process of deserted mine reforestation and role of symbiotic microorganisms in it, and improvement of reforestation
  • Inhibiting factors of tree regeneration and improvement of regeneration
  • Relationship between responses of trees against biotic / abiotic stress and gene expression / metabolites
  • Mechanisms of useful metabolites formation of woody plants and their effective production
