Blue Light-Induced Chloroplast Relocation in Arabidopsis thaliana as Analyzed by Microbeam Irradiation
Abstract
Chloroplast relocation in mesophyll cells of Arabidopsis thaliana was observed microscopically and analyzed by microbeam irradiation. Chloroplasts located along the anticlinal walls in dark-adapted cells. When part of a cell was irradiated with a microbeam of high fluence rate blue light (B) simultaneously with background red light (R) on the whole cell, the chloroplasts moved towards the B-irradiated area, but did not enter the beam. The background R illumination activated cytoplasmic motility as well as chloroplast movement. Without R illumination, there was little chloroplast relocation. In light-adapted cells in which the chloroplasts were spread over the cell surface perpendicular to the incident light, R-illumination had the same effect. Under background R, the chloroplasts moved out of the area irradiated with a B microbeam of 8 or 30 W m(-2) (avoidance response), but chloroplasts outside the beam moved towards the area irradiated with the B microbeam (accumulation response). These results suggest that the signals for accumulation and avoidance responses were generated in a single cell by high fluence rate B. cry1cry2, npq1 and nph1 mutants showed B-induced chloroplast relocation. Both the accumulation and avoidance responses were observed in all the mutants, although in the nph1 mutant, the sensitivity of accumulation movement was slightly lower than that of the wild type. We discuss the possible photoreceptor for B-induced chloroplast relocation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
