Gustav Senn (1875–1945): The pioneer of chloroplast movement research

Kataoka, Hironao·2015·Journal of Integrative Plant Biology

Abstract

Gustav Senn analyzed for the first time light‐induced movement and arrangement of chloroplasts. Using many plant species he performed physiological analyses of chloroplast migration in response to external stimuli, with emphasis on light. He determined light paths within a cell by measuring refractive indices and optical thickness of cellular compartments and confirmed that chloroplasts migrate towards the region where the light intensity is optimum. After 6 to 7 years' concentrated study, Senn published the famous monograph “Die Gestalts‐ und Lageveränderung der Pflanzen‐ Chromatophoren”(The Changes in Shape and Position of Plant Chloroplasts) in 1908. This book has stimulated many plant physiologists and photobiologists, because Senn not only thoroughly classified and defined various types of light‐induced chloroplast migration but also already described possible interaction of different photoreceptor systems in Mougeotia more than 50 years before the discovery of phytochrome. This book also contains still useful experimental hints and overlooked findings on the interaction between light and other factors, such as temperature, water content, and nourishment. After publishing this book, Senn retreated from the study of chloroplasts and became a researcher of the Greek philosopher, Theophrastus. In this review, I introduce his biographical background and then summarize some of his key research accomplishment. Hironao Kataoka

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.
