Abstract
This study aimed to compare the effects of increasing concentrations of cadmium (Cd) on the growth rates, content of photosynthetic pigments, and ultrastructure of Palisada flagellifera (J. Agardh) K. W. Nam (Ceramiales, Rhodophyta). Plants were cultivated under photosynthetically active radiation (PAR) of 70 μmol photons m−2 s−1 with 0 (control), 2.5, 5.0, 7.5, 10 20, 40, and 60 μM of cadmium (CdCl2) for 7 days. Subsequently, the apical segments of P. flagellifera were analyzed under transmission microscopy, and both growth rates and photosynthetic pigments were measured. Growth rates in P. flagellifera samples gradually decreased with the increasing concentration of Cd in culture medium. Palisada flagellifera exposed to 20, 40, and 60 μM of Cd showed thallus bleaching and partial necrosis. Damage to thylakoid membranes and discoloration, as well as reduced phycobiliproteins, were more evident at concentrations of Cd higher than 40 µM. Palisada flagellifera samples treated with Cd also showed cell wall thickness triggered by the activation of mechanical defense mechanisms to prevent entry of Cd into the cytoplasm, as well as the increase of chlorophyll a content. Overall, these results indicate that exposure to cadmium in concentrations exceeding 40 µM is sublethal to P. flagellifera.
