Seasonal variability in irradiance affects herbicide toxicity to the marine flagellate Dunaliella tertiolecta
*Correspondence: Sascha B. Sjollema, Department of Aquatic Ecology and Ecotoxicology, Institute for Biodiversity and Ecosystem Dynamics, University of Amsterdam, Science Park 904, 1098 XH Amsterdam, Netherlands e-mail: [email protected] Photosynthetically Active Radiation (PAR) and Ultraviolet Radiation (UVR) of the solar spectrum affect microalgae directly and modify the toxicity of phytotox...
متن کاملIsolation of Intact Chloroplasts from Dunaliella tertiolecta.
Cells of Dunaliella tertiolecta from the log phase of growth were broken by rapid extrusion at low pressure through a Yeda press and the chloroplasts were isolated by centrifugation through a Percoll gradient. Osmolarity of the growth media, the suspending media, and the Percoll gradient was kept identical to minimize change in chloroplast volume and mitochondrial entrapment. The isolated intac...
متن کاملAntioxidative responses of two marine microalgae during acclimation to static and fluctuating natural UV radiation.
Photoacclimation properties were investigated in two marine microalgae exposed to four ambient irradiance conditions: static photosynthetically active radiation (PAR: 400-700 nm), static PAR + UVR (280-700 nm), dynamic PAR and dynamic PAR + UVR. High light acclimated cultures of Thalassiosira weissflogii and Dunaliella tertiolecta were exposed outdoors for a maximum of 7 days. Dynamic irradianc...
متن کاملResponse of the marine microalga Dunaliella tertiolecta (Chlorophyceae) to copper toxicity in short time experiments.
Heavy metals are introduced into aquatic ecosystems from industrial wastes, agricultural runoff and mining activities. The toxicity of heavy metal ions in solution to microalgae is well known. The essentiality and toxicity of heavy metals has been a subject of extensive research (Stokes 1983). From a biological point of view, heavy metals can be divided into two categories: essential and non-es...
متن کاملA PSTTLRE-form of cdc2-like gene in the marine microalga Dunaliella tertiolecta.
To understand the genetic control of algal cell division cycle that pertains to phytoplankton bloom dynamics in the sea, we cloned and analyzed a gene coding for a cyclin-dependent kinase (CDK) for the chlorophyte Dunaliella tertiolecta. The cDNA cloned, 1061 bp long, contained an open reading frame of 314 amino acids. FASTA and GAP analyses showed that this sequence was most homologous to cdc2...
