M. Ueda et al., Direct observation of the target cell for leaf-movement factor using novelfluorescence-labeled probe compounds: Fluorescence studies of nyctinasty in legumes. Part 1, TETRAHEDR L, 42(23), 2001, pp. 3869-3872
We synthesized fluorescence-labeled probe compounds hearing AMCA (1). NBD (
2). and dansyl (3) groups as the fluorescent functionality, In these probe
compounds. NBD-type probe. 2. showed leaf-opening activity at 5x10(-6) M. T
he bioactivity of 2 is one-fifth as strong as that of the natural product,
potassium isolespedezate (6). We carried out the binding experiment using 1
in a plant body. (C) 2001 Elsevier Science Ltd. All rights reserved.
