蛍光標識による植物ホルモンの生体イメージング(<特集>ライブセルイメージング)

抄録

Plant hormones are small molecules and coordinately regulate plant growth and development throughout the plant life. The action of plant hormones is regulated by the distribution and sensitivity of plant hormones modulated by metabolism, transport and signaling. The distribution of plant hormones in the cell and tissue is determined by the rate of biosynthesis and inactivation and transport. Live cell imaging by means of fluorescently-labeled plant hormones is useful approach to obtain spatio-temporal information of plants hormones in living organism. Especially, fluorescently-labeled auxins that designed to be specific to transport system are powerful tool to understand the regulatory process underlying auxin distribution. Here, we give an overview of fluorescent-labeling for plant hormones.
