Measuring the ratio of the number of photooriented chloroplasts to the total number of chloroplasts, we found that photoorientation of chloroplasts in protonemata of the fern Adiantum capillus-veneris could be induced by brief irradiation with polarized red light. After irradiation with red light (R) of 3 or 10 min, orientational movement was detected as early as 10 min after the irradiation; it continued during the subsequent dark period for 30-60 min, after which chloroplasts gradually dispersed again. When R-treated protonemata were irradiated briefly with a second 10-min pulse of R, 60 min after the onset of the first irradiation, the orientational response of chloroplasts was again observed. Typical red/far-red photoreversibility was apparent in the response, indicating the involvement of phytochrome. By contrast, irradiation with polarized blue light for 10 min was ineffective, while irradiation with blue light (B) at the same fluence for a longer period of time clearly induced the photoorientation of chloroplasts. It is likely that long-term irradiation is necessary for the response mediated by a blue-light receptor. When protonemata were irradiated with far-red light (FR) immediately after R or after a sub-sequent dark period of 10 min, the magnitude of the orientational response was smaller and chloroplasts dispersed more quickly than those exposed to R alone. When FR was applied at 50 min, when the response to R had reached the maximum level, chloroplasts again dispersed rapidly to their dark positions. These results indicate that P_<FR> not only induces the photoorientation movement of chloroplasts but also fixes the chloroplasts at the sites to which they have moved as a result of photoorientation.
