摘要: The motility and step-down photophobic responses of Euglena are influenced by inorganic organic anions. Persistent (with Ca2+, Mg2+ K+ present) is supported with chloride or sulfate but not acetate, nitrate propionate as the only added Cells in media containing acetate displayed a cell aggregation (clumping) behavior that was both red light sensitive and, under some conditions, accompanied suppression response. Addition sodium salts (Cl-, SO 4 2- , propionate) to cells Cl- based had differential effects on duration induced blue removal: anions alter In addition, all showed constant response following repeated stimulation. SO4 2- media, however, summation This latter effect reversible overcome addition
