Outline of Final Research Achievements

Although issue growth is coordinated along the developmental time scale in animals, the molecular basis remains elusive. We examined the mechanism by which tissue growth is coordinated in animals that causes developmental delay, by using a series of Drosophila mutant that have a mutation in gene encoding ribosomal protein, Minute. Minute show significant delay in the progression of their larval period, but importantly they develop to almost normal adult flies. We found that developmental delay cooperate with upregulation of Wingless expression in wing discs, which trigger “cell-turnover” and the following normal wing morphogenesis during development.
