The effect of far-red light was cancelled completely by red light irradiated immediately after the far-red light. In order to elucidate the photoreceptor(s) for photocontrol in the induction of haustoria, action spectra for the photo-induction and its reversion were determined in the wavelength region from 340 nm to 800 nm using the Okazaki Large Spectrograph. The action spectrum for the induction of haustoria had a pronounced peak at 740 nm and a small peak at 420 rim, while the action spectrum for reversal of the induction had a pronounced peak at 660 nm and a small peak at 380 rim. These results indicate that phytochrome is involved in the photocontrol of induction of haustoria in Cuscuta japonica. Considering the far-red/red reversibility, it was suggested that phytochrome B is the photorecepter. This is the first reliable evidence of phytochome participation on development of haustoria in parasitic plants.}, pages = {935--940}, title = {Phytochrome participation in induction of Haustoria in Cuscuta japonica, a holoparasitic flowering plant}, volume = {38}, year = {1997} }
