Outline of Final Research Achievements

We could substitute past knowledge or add a new topic to the present textbooks during this research project. Namely, (1) the relationship between the ploidy level regulated by endoredupication and cell size is not as simple as formerly believed (Tsukaya 2013; Katagiri et al. 2016: the latter received The Hirase Award from The Japanese Society of Plant Morphology); (2) spatial-temporal regulation of leaf meristem can be explained by a classic morphogen-like diffusion of AN3 protein (Kawade et al. 2017).
