Asynchronous cultures of wild-type Euglena gracilis were tested for their morphophysiological response to 10 mM MnSO4. Growth was only moderately slowed (15%), while oxygen evolution was never compromised. Inductively coupled plasma analyses indicated that the Mn cell content doubled with respect to controls, but no signs of localised accumulation were detected with X-ray microanalysis. Evident morphological alterations were found at the plastid level with transmission electron microscopy and… CONTINUE READING
