The effect of lanthanides on photosynthesis, growth, and chlorophyll profile of the green alga Desmodesmus quadricauda

Original language description

Lanthanides (La, Gd, Nd, Ce) accumulated in the green alga Desmodesmus quadricauda but their intracellular localizations were distinctly different: lanthanum and gadolinium were localized in cytoplasm, while neodymiumand cerium were in the chloroplast. The effect of lanthanum and neodymium, as representatives of these twogroups, on growth, chlorophyll content and photosynthetic rate at different light intensities was studied. At the lowestlight intensity used (50 umol photons m-2 s-1), in the presence of lanthanides (Nd), growth was enhanced by asmuch as 36 % over lanthanide free control, and the photosynthetic rate increased by up to 300 %. At high lightintensities (238, 460, and 750 lmol photons m-2 s-1), photosynthetic rate increased markedly, but there was nosignificant difference between rates in the presence or absence of lanthanides. However, growth, measured as apercentage of dry weight, if compared with lanthanide free control, increased at all light intensities (31, 39, and 20 %,respectively). The total amount of chlorophyll after lanthanide treatment increased by up to 21 % relative to thecontrol culture, mainly due to an increase in the level of chlorophyll b. Addition of lanthanides caused a change inthe chlorophyll a/b ratio from 4.583 in control cultivation, to 1.05. Possible mechanisms of lanthanide-induced photosynthetic change, alterations in photosynthetic structures, and increases in growth are discussed and compared withfindings in higher plants. The hypothesis that the lanthanide effect could be due to formation of lanthanide-pheophytinswas not confirmed as lanthanide pheophytins were not found in D. quadricauda. Furthermore, we have shown thatthe preferential incorporation of heavy isotopes of magnesium, namely 25Mg and 26Mg, into chlorophyll duringphotosynthesis that occurred in controls was diminished in the presence of lanthanides.
