Abstract:

Cocultivation of iron-limited cells of the cyanobacterium Anabaena flos-aquae (Lyng.) Brèb. and the green alga Chlamydomonas reinhardtii Dangeard resulted in growth of Anabaena but not Chlamydomonas, even in the presence of excess exogenous iron. This effect was also observed during the cultivation of Chlamydomonas in a medium in which iron-limited Anabaena cells had been growing, but were removed prior to culture of Chlamydomonas. Conversely, iron-limited Chlamydomonas cells grew very well in medium from iron (nutrient)-sufficient, phosphate-limited, and nitrogen-limited Anabaena cultures. Iron-limited Anabaena cultures produced siderophores, while the other types of Anabaena cultures did not. Treatment of Anabaena iron-limited medium with activated charcoal completely removed the inhibitory effect on Chlamydomonas growth, and boiling the medium removed most of the inhibitory effect. Both the charcoal and the boiling treatments also removed siderophores from the medium. Partially purified Anabaena siderophore preparations were also inhibitory to Chlamydomonas growth. The inhibitory effect of iron-limited Anabaena medium could be partially overcome by addition of excess micronutrients (especially cobalt copper) but not by addition of iron. We suggest that Anabaena-derived siderophores, present only in iron-limited Anabaena medium, inhibit the growth of Chlamydomonas cells via a previously uncharacterized toxicity. This effect is different from previously described experiments in which cyanobacterial siderophores suppressed green algal growth via competition for limiting amounts of iron.Key words: Anabaena, Chlamydomonas, cocultivation, iron limitation, micronutrients; siderophores.

Abstract:

The present work tested the food selectivity of the cladoceran Ceriodaphnia quadrangula (O. F. Müller, 1785) and its impact on competition outcome between Chlorella vulgaris Beijerinck, 1890 and Chlamydomonas globosa J. W. Snow, 1902. Freshwater green algae, Chlorella, have heavy cell walls and their size usually exceeds the lower limits of limb size of Ceriodaphnia. According to the optimal foraging theory, it is speculated that Ceriodaphnia would graze on the more exposed and relatively larger Chlamydomonas rather than on Chlorella, and this process would lead to small-sized Chlorella becoming a superior competitor in the presence of Ceriodaphnia. This work used Ceriodaphnia, Chlamydomonas globosa and Chlorella vulgaris to test this hypothesis. The grazing experiment showed that Ceriodaphnia preferred Chl. globosa to Ch. vulgaris, regardless of the concentration and relative abundance of these algae. The decrease in relative abundance of high-quality Chlamydomonas in Chlamydomonas-Chlorella assemblages did not diminish the grazing efficiency of Ceriodaphnia on this algal species, but increased the selectivity of small-sized cells of Chlorella. However, when the concentration of Chlamydomonas was extremely high, the grazing of Ceriodaphnia on Chlamydomonas decreased. In competition experiments, it was observed that the presence of Chlamydomonas restrained the growth potential of Chlorella; however, the introduction of Ceriodaphnia into the competing environment weakened this influence and to some extent enhanced the growth ability of Chlorella. The different densities of Ceriodaphnia had an obvious influence on the competition outcome between Chlamydomonas and Chlorella.

Abstract:

Selenium (Se) is an essential micro-element for many organisms, including Chlamydomonas reinhardtii, and is required in trace amounts. It is obtained from the 21st amino acid selenocysteine (Sec, U), genetically encoded by the UGA codon. Proteins containing Sec are known as selenoproteins. In eukaryotes, selenoproteins are present in animals and algae, whereas fungi and higher plants lack them. The human genome contains 25 selenoproteins, most of which are involved in antioxidant defense activity, redox regulation, and redox signaling. In algae, 42 selenoprotein families were identified using various bioinformatics approaches, out of which C. reinhardtii is known to have 10 selenoprotein genes. However, the role of selenoproteins in Chlamydomonas is yet to be reported. Chlamydomonas selenoproteins contain conserved domains such as CVNVGC and GCUG, in the case of thioredoxin reductase, and CXXU in other selenoproteins. Interestingly, Sec amino acid residue is present in a catalytically active domain in Chlamydomonas selenoproteins, similar to human selenoproteins. Based on catalytical active sites and conserved domains present in Chlamydomonas selenoproteins, we suggest that Chlamydomonas selenoproteins could have a role in redox regulation and defense by acting as antioxidants in various physiological conditions.

Abstract:

Chlamydomonas in the traditional sense is one of the largest green algal genera, comprising more than 500 described species. However, since the designation of the model organism C. reinhardtii as conserved type of this genus in 2007, only two species remained in Chlamydomonas. Investigations of three new strains isolated from soil samples, which were collected near Lake Nakuru (Kenya), demonstrated that the isolates represent a new species of Chlamydomonas. Phylogenetic analyses of nuclear SSU and ITS rDNA and plastid-coding rbcL sequences have clearly revealed that this species is closely related to C. reinhardtii and C. incerta. These results were confirmed by cross experiments of sporangium wall autolysins (VLE). All species belonged to the VLE group 1 sensu Schlösser. The comparison of the ITS-1 and ITS-2 secondary structures showed several compensatory base changes among the three species. In addition, the rbcL amino acid composition was also species-specific. The genus Chlamydomonas was phylogenetically closely related to the colonial families Goniaceae, Tetrabaenaceae and Volvocaceae. Chlamydomonas debaryana (VLE group 2) formed a separate clade among these colonial families of the Volvocales, a species of which autolysin dissolved the sporangium walls of the members of VLE group 1, suggesting its close relationship to Chlamydomonas. As consequence of our results, we propose Chlamydomonas schloesseri sp. nov. for the new Kenyan isolates. We also propose a new combination of C. debaryana to the newly erected genus Edaphochlamys.

Abstract:

Photosystem I (PSI) catalyses the light driven electron transfer from plastocyanin/ cytochrome c6 on the luminal side of the thylakoid membrane to ferredoxin/ flavodoxin at the stromal side via a chain of electron carriers. PSI is a multi-protein membrane complex composed of a large number of polypeptide subunits, designated PsaA to PsaO. There are key differences in subunit composition between prokaryotic and eukaryotic PSI complexes. For example, PsaG, PsaH, PsaN and PsaO are all absent from cyanobacterial PSI. In eukaryotes the genes for the PSI subunits are distributed between the nuclear and chloroplast genomes. This thesis describes a series of molecular-genetic studies using the model photosynthetic eukaryote Chlamydomonas reinhardtii, aimed at understanding various aspects of the eukaryotic PSI. The nuclear gene encoding the PsaN subunit from C. reinhardtii was cloned and characterised. The psaN gene was shown to be present as a single copy in the genome and northern analysis indicated that the expression of this gene is light-induced. Antibodies were raised to the mature PsaN protein and attempts were made to down- regulate psaN gene expression using an RNA antisense approach. Several PSI mutants were investigated using western analysis. A mutant lacking PsaJ showed significantly reduced levels of PsaN protein accumulation, while a mutant lacking PsaF showed no detectable levels of PsaN, indicating that these two subunits may interact with PsaN on the lumenal side of the PSI complex. The role of the 22 ?-carotene molecules associated with the PSI complex was investigated. Molecular and biophysical analysis of a carotenoid deficient mutant established that the PSI complex is assembled and functional despite the loss of carotenoids and the PsaN protein from the complex. The crystal structure of cyanobacterial PSI reveals two possible electron transfer branches bound to the PsaA and PsaB subunits, which display a remarkable symmetry. However, a key difference is a tryptophan residue located between the PsaB-bound phylloquinone and the iron-sulphur centre Fx, which is not conserved in PsaA. The tryptophan residue was substituted with a glycine using site-directed mutagenesis. The mutant was unable to grow photoautotrophically and biophysical analysis revealed that electron transfer on the PsaB branch was partially blocked.

Abstract:

Microalgae have become increasingly important in the biotech sector and are currently exploited for their natural products. In recent years efforts have also been directed towards establishing them as production platforms for recombinant proteins. The aim of this thesis is to investigate the feasibility of Chlamydomonas reinhardtii as a production platform for highvalue products expressed in the chloroplast of the alga. A cytochrome P450 was introduced into the chloroplast of C. reinhardtii as a proof-of-concept study. The model enzyme CYP79A1 was successfully targeted into the chloroplast membranes and was found to be active. A bifunctional diterpene synthase, TPS4, was also expressed in the chloroplast of C. reinhardtii. TPS4 could be purified to homogeneity and is the largest enzyme expressed in the chloroplast to date. The two transgenic strains expressing CYP79A1 and TPS4 were investigated for their ability to withstand industrial growth conditions. The cell wall deficient strains were successfully cultivated in 100 L photobioreactors using a mixotrophic growth regime. They reached dry weights of 0.3 g/L and the expression of CYP79A1 and TPS4 was detected over the entire growth period. Taken together these data suggest that C. reinhardtii could be an attractive platform for recombinant protein production. Two enzymes with biotechnological relevance were expressed in the chloroplast of the alga and the transgenic cell wall deficient strains were successfully cultivated on a semi-industrial scale.

Abstract:

Abstract Drinking water contaminated with metal ions can cause negative health effects in humans. Acute heavy metal poisoning can cause such symptoms as vomiting and fainting, while chronic heavy metal poisoning can lead to organ failure and death. It has previously been shown that concentration of metal ions in water solution was decreased by algae. This paper reports a study to examine the ability of two Chlamydomonas reinhardtii algae strains to remove copper ions from water solution. Chlamydomonas reinhardtii was chosen for this study because it is easy to culture, and can be used to generate strains with a higher efficiency to remove metals. In this study, the three-factor, two-level full factorial design was used to conduct experiments. Three factors were algae strain, initial copper concentration, and exposure time. Two levels of the algae strain are: cc125 — the Chlamydomonas reinhardtii strain found commonly in the wild, and AGG1 — an experimentally modified Chlamydomonas reinhardtii strain. Two levels of initial copper concentration and exposure time were 1.5 and 3 ppm, and 2.5 and 5 hours, respectively. Copper concentration in the water solution after experiments was measured using inductively coupled plasma-mass spectrometry, or ICP-MS. Statistical analysis showed that algae strain was the only factor that significantly affected percentage decrease in copper concentration, at the significance level of 0.05. The cc125 strain decreased copper concentration more efficiently than the AGG1 strain. The cc125 strain decreased copper concentration by 97% for the water solution with an initial copper concentration of 1.5 ppm, and by 90% for the solution with an initial copper concentration of 3 ppm. Copper concentrations of all solutions treated by the cc125 strain were below the Environmental Protection Agency pollution threshold level of 1.3 ppm.

Abstract:

The forces exerted on the flagellum of the swimming alga Chlamydomonas reinhardtii by surrounding fluid are estimated from video data. “Wild-type” cells, as well as cells lacking inner dynein arms (ida3) and cells lacking outer dynein arms (oda2) were imaged (350 fps; 125 nm). Digital image registration and sorting algorithms provide high-resolution descriptions of the kinematics of the cell body and flagellum. The swimming cell is then modeled as an ellipsoid in Stokes flow, propelled by viscous forces that depend linearly on the velocity of the flagellum. The coefficients (CN and CT) that related normal and tangent forces on the flagellum to corresponding velocity components are estimated from equilibrium requirements. Their values are consistent among all three genotypes and similar to theoretical predictions.

Abstract:

Abstract In this work, we focus on the motility behavior of two model microorganisms widely used in the study of active fluids: Chlamydomonas reinhardtii microalga and Synechocystis sp. Cyanobacterium. Understanding the physiological responses of microorganisms under variable environmental conditions is essential for bioreactor engineering. Yet, most of the previous studies focused on the observation of cellular motility regardless of the growth process. Here, we measure the motility of Chlamydomonas reinhardtii and Synechocystis sp. during their growth when subjected to different intensities of hydrodynamic shear stress. The results demonstrate a significant difference in the motility response of the two species against the applied hydrodynamic shear stress. Mechanical agitation appears to affect the motility of Chlamydomonas reinhardtii microalgae by stimulating the growth process and increasing the magnitude of the cellular swimming velocity. The motility varies following 3 different phases: the rising phase starting almost at the middle of the exponential growth phase, and the decay and damped phases during the stationary phase. This behavior is described using a linear model for the rising phase and a damped oscillatory model for the decay and damped phases. The motility of Synechocystis does not follow a well-defined pattern in time. However, it seems that the peak of the swimming velocity occurs always in the middle of exponential phase of growth. Synechocystis cells show a high endurance to the applied shear such that the global effect of agitation intensity on their motility is insignificant.

Abstract:

The steady-state level of a given mRNA is determined by its rates of transcription and degradation. The stabilities of chloroplast mRNAs vary during plant development, in part regulating gene expression. Furthermore, the fitness of the organelle depends on its ability to destroy non-functional transcripts. In addition, there is a resurgent interest by the biotechnology community in chloroplast transformation due to the public concerns over pollen transmission of introduced traits or foreign proteins. Therefore, studies into basic gene expression mechanisms in the chloroplast will open the door to take advantage of these opportunities. This project was aimed at gaining mechanistic insights into mRNA processing and degradation in the chloroplast and to engineer transcripts of varying stability in Chlamydomonas reinhardtii cells. This research uncovered new and important information on chloroplast mRNA stability, processing, degradation and translation. In particular, the processing of the 3' untranslated regions of chloroplast mRNAs was shown to be important determinants in translation. The endonucleolytic site in the 3' untranslated region was characterized by site directed mutagensis. RNA polyadenylation has been characterized in the chloroplast of Chlamydomonas reinhardtii and chloroplast transformants carrying polyadenylated sequences were constructed and analyzed. Data obtained to date suggest that chloroplasts have gene regulatory mechanisms which are uniquely adapted to their post-endosymbiotic environment, including those that regulate RNA stability. An exciting point has been reached, because molecular genetic studies have defined critical RNA-protein interactions that participate in these processes. However, much remains to be learned about these multiple pathways, how they interact with each other, and how many nuclear genes are consecrated to overseeing them. Chlamydomonas is an ideal model system to extend our understanding of these areas, given its ease of manipulation and the existing knowledge base, some of which we have generated.
