High irradiance blue light affects cortical microtubules in the green alga Mougeotia scalaris

Abstract

High irradiance blue light (HIBL), but not red light, diminished anti-tubulin indirect immunofluorescence of cortical microtubules in the green alga Mougeotia. Quantitation of MT-specific immunofluorescence by digital image analysis revealed taxol to counteract the HIBL-elicited decrease in immunolabelling. Taxol caused no significant increase of immunofluorescence in red light.
