Welcome to Laboratory of Plant Functional Analyses (Misato's Lab)!

From 1st April 2019, Laboratory of Plant Functional Analyses led by Misato Ohtani has been started in Kashiwa Campus of The University of Tokyo. As the first members, Dr. Toshi Arae, Ms. Ayumi Ihara, Ms. Megumi Takahashi, and Ms. Mami Yokoyama  are joined.


From April 2019, Misato Ohtani's lab

has been started

in The University of Tokyo!



In this laboratory,  we aim to obtain molecular information on how plants sense and react to environmental conditions, to control flexibly cell proliferation and differentiation for an active control of individual.

Totipotency of Plant Cells

One of characteristics of plant cells is “totipotency”. This nature can be recognized through, for example, organ regeneration. Now we propose the hypothesis that RNA metabolism would support the expression of totipotency in plant cells. These RNA metabolism studies will be deepened, by further analysis of molecular mechanisms controlling the cell potency of plants.

Biopolymer Dynamics

Generally mobility of plants is quite low, thus plant cells should constantly response to changes in environmental factors, to maintain the homeostasis of cell function. We elucidate roles for biopolymer dynamics in environmental response of plants, focusing on RNA (the essential molecules for gene expression) and cell walls (the first barrier against the external environment for plant cells).

Woody Biomass Biosynthesis

Aggravated environmental problems strongly require us to change the style of social activities. Towards a sustainable social system, we promote to understand the biosynthesis of woody biomass. The understanding of secondary cell wall biosynthesis as a system and the explore of evolutionary origin of secondary cell walls are pursued by comparative- and trans-omics approaches.
