Green flagellar autofluorescence in brown algal swarmers and their phototactic responses

A flavin-like green autofluorescent substance is noticed to occur in one of the flagella of flagellated cells in the Phaeophyceae, Chrysophyceae, Synurophyceae, Xanthophyceae and Prymnesiophyceae. In the phaeophycean swarmers the autofluorescence occurs in the posterior flagellum throughout its length. It is considered to be involved in the photoreception… (More)
