Overview
of Research
@@Plants must have a suitable size and shape, for performing an efficient
life. We have been studying the mechanisms of growth regulation and morphogenesis
in higher plants. Plant cells are surrounded by well-developed cell walls,
which provide the protoplasts with the structural rigidity. Therefore,
the cell wall determines most directly the size and shape of plant cells.
During plant development, the mechanical properties of the cell wall dramatically
change through the structural modifications. The cell wall plays an important
role not only in the regulation of plant growth and morphogenesis, but
also in the regulation of other various functions in plants.
@@The physiological functions of the cell wall are sustained
by the active metabolic turnover of its constituents.
The metabolism of cell wall constituents is fundamentally
directed by a genetic program. At the same time, plants
are surrounded by a variety of environmental signals,
which greatly modify the genetic program. Actually,
when plants are subjected to the environmental signals,
the mechanical properties of the cell wall are prominently
changed. Plant hormones are involved in transduction
of perceived environmental signals. The hormones also
play a role as a mediator of gene functions. Thus, processes
of growth regulation and morphogenesis, and therefore
of regulation of various plant functions, are summarized
as the following series of events:
@@@Environmental signals ¨ Hormones ¨ Genes ¨ Hormones
¨ Cell walls ¨
@@We are interested in mechanisms of the whole of the events, and studying
them with a combination of physiological, biochemical, molecular biological,
morphological, and physical approaches. One of themes we are currently
focusing is the mechanism of gravity responses in plants. We are analyzing
them with both space and ground-based experiments.
