Double fluorescence-labeling study on genus Albizzia using a set of fluorecence-labeled leaf-movement factors to identify the spatial distribution of their receptors

Abstract

We synthesized rhodamine-labeled leaf-opening factor of genus Albizzia. We carried out double fluorescence-labeling study on genus Albizzia using rhodamine-labeled leaf-opening factor and fluorescein-labeled leaf-closing factor. This study showed that both probes bound the same motor cell. These results indicated that each motor cell had both receptors for leaf-opening and leaf-closing factors.
