Comparison of methyl jasmonate and cadmium effect on selected physiological parameters in Scenedesmus quadricauda (Chlorophyta, Chlorophyceae)

Popis výsledku v původním jazyce

Effect of methyl jasmonate (MeJA) in the concentrations of 10 or 100 mu M on selected physiological parameters in Scenedesmus quadricauda (Turp.) Breb. after 24 h of exposure was studied. Results were compared with the application of general toxic metal(cadmium, Cd) to identify MeJA-specific responses. Accumulation of reactive oxygen species (ROS; hydrogen peroxide and superoxide) was the most elevated by 10 mu M MeJA and 100 mu M Cd, while total chls showed decrease (Cd) and increase (MeJA) in these variants. The amount of carotenoids and cell viability were affected neither by MeJA nor by Cd application. The sum of free amino acids was considerably elevated by 10 mu M Cd (increase in histidine, threonine, arginine, leucine, and lysine mainly) but depleted by 100 mu M MeJA (14 from 17 compounds decreased), while accumulation of soluble proteins was unaffected by Cd and enhanced by MeJA. Cadmium application reduced the amount of Ca and also Mg in the case of 100 mu M Cd, while MeJA ha
