High Light-induced Sign Change of Gravitaxis in the Flagellate Euglena gracilis is Mediated by Reactive Oxygen Species

Euglena gracilis responds to abiotic stress factors (high light, salinity, heavy metals) with a sign change of its gravitactic behavior. This phenomenon is oxygen dependent and can be suppressed by the application of the reductant dithionite. It is not mediated by the photoreceptor since also blind...
