 note = {Autonomous helical movement of plant organs, originally termed circumnutation by Charles Darwin in the 19th century, is ubiquitously observed in land plants. In Cuscuta campestris, a stem parasitic plant whose stems coil around the host stem during parasitization, this movement plays a critical role in searching for a host. Although patterns of circumnutation have been extensively investigated in several species under different environmental conditions, such as variable light and temperature, and after chemical exposure, the mechanisms underpining this movement remain largely unknown. This is partly due to the lack of suitable methods for acquiring high-resolution spatio-temporal images of plant organs during circumnutation. To address this issue, we designed a time-lapse image acquisition system with two video cameras: one positioned to capture images from above and the other to capture images from the side of the plant. Using this camera system, images of circumnutating C. campestris shoots were captured under different light conditions, and the effects of light quality on the winding angle and rotation rate of circumnutation were quantified. The results indicate the utility of this imaging system in evaluating the effects of light quality on circumnutation, and highlight the need for improvements in data resolution for 3D image analysis., Departmental Bulletin Paper, 原著, 2020年度 神奈川大学総合理学研究所共同研究助成論文},
