Outline of Final Research Achievements

Spatial and temporal dynamics of RNA silencing in the life cycle of plants were analyzed in terms of exploiting quantitative modification of plant metabolites through gene expression control mediated by RNA silencing. Using transgenic soybean plants that carry a reporter gene, the following points were revealed: the induction and spread of RNA silencing during plant growth and its reset during reproduction occur in each generation; specific features of the architecture of the plant, in addition to the mechanisms conserved in plants, are involved in the diversity of these phenomena.
