| Outline of Final Research Achievements |
Forest ecosystem management requires accurate evaluation on environmental impacts on trees under multiple stressors and complex physiological processes. Here we studied a method of environmental impact assessments by genome-wide gene expression profile of leaf in Siebold's beech forests. Over hundreds number of indicator-genes for decline of tree vigor and impact of stressors; oxidation, high-temperature and drought were screened out, and their expression pattern were indexed by PCA. The increasing score of decline index was positively correlated with score of oxidation and/or drought. The oxidation index was positively correlated with tropospheric ozone across Japan. Bayesian networks analysis based on gene expression profile resulted in a causality inference in which high ozone caused low shoot growth with dysfunctional many genes activity in a beech forest. Our studies showed genomic approach provides a promising technique of environmental impact assessments on forest trees.
