Introduction GBM is very complex, it includes surgical resection of tumor followed by radiotherapy and chemotherapy Glioblastoma multiforme (GBM) is one of the most (Delgado-López & Corrales-García, 2016). Despite common and malignant primary brain tumor in adults. optimal treatment, high resistance of tumor cells to GBM grows rapidly and has a high rate of invasion and chemotherapy and radiotherapy, GBM has very poor angiogenesis capacity but they often do not metastasize survival rate. Since conventional therapies not sufficient out of the brain. This tumor type carries the highest to combat this disease there is a great need to develop incident rate among brain and central nervous system new treatment approaches. tumors with the incident rate of 3.19/100.000 Phytochemicals are natural plant derived population (Thakkar et al., 2014). On the other hand, compounds and known to be as a great source for GBM has worst prognosis among other types of brain development of many drugs. Many phytochemicals and cancers (Hanif et al., 2017) . The median survival for their derivatives are known to have high antitumor GBM is 15 months and less than 5% of patients survive potential for cancer treatment. In addition, it is known 5 years post-diagnosis (Delgado-López & Corrales- that phytochemical-based agents increase treatment García, 2016). The standard treatment approach

That role and associated emerging infection patterns remain particularly elusive for eukaryotic phytoplankton and their viruses. Here we used a vast number of strains from the model system Emiliania huxleyi/Emiliania huxleyi Virus to quantify parameters such as growth rate (µ), resistance (R), and viral production (Vp) capacities. Algal and viral abundances were monitored by flow cytometry during 72-h incubation experiments. The results pointed out higher viral production capacity in generalist EhV strains, and the virus-host infection network showed a strong co-evolution pattern between E. huxleyi and EhV populations. The existence of a trade-off between resistance and growth capacities was not confirmed.

Corresponding author: [email protected] Abstract Chlamydomonas (Volvocales, Chlorophyceae) is a large polyphyletic genus that includes numerous species that should be classified into independent genera. The present study aimed to examine the authentic strain of Chlamydomonas meslinii and related strains based on morphological and molecular data. All the strains possessed an asteroid chloroplast with a central pyrenoid and hemispherical papilla; however, they were different based on cell and stigmata shapes. Molecular phylogenetic analyses based on 18S rDNA, atpB, and psaB indicated that the strains represented a distinct subclade in the clade Chloromonadinia. The secondary structure of ITS-2 supported the separation of the strains into four species.

BCollege of the Atlantic, 105 Eden Street, Bar Harbor, ME 04609, USA. CCorresponding author. Email: [email protected] Abstract. Despite a large body of work on the serpentine-substrate effect on vascular plants, little work has been undertaken to describe algal communities found on serpentine soils derived from peridotite and other ultramafic rocks. We report a preliminary study describing the occurrence of algae and cyanoprokaryotes on mafic and ultramafic substrates from South Africa. Results suggest that slope and aspect play a key role in species diversity and community composition and, although low pH, nutrients and metal content do not reduce species richness, these edaphic features also influence species composition. Further, typical soil genera such as Leptolyngbya, Microcoleus, Phormidium, Chlamydomonas, Chlorococcum and Hantzschia were found at most sites. Chroococcus sp., Scytonema ocellatum, Nostoc linckia, Chlorotetraedron sp., Hormotilopsis gelatinosa, Klebsormidium flaccidium, Pleurococcus sp. and Tetracystis elliptica were unique to one serpentine site. The preliminary survey provides directions for future research on the serpentine- substrate effect on algal and cyanoprokaryote diversity in South Africa. Additional keywords: algae, cryptogamic ecology, serpentine geoecology, species diversity.

Additional information is provided by the scientific literature or other international reviews. Since release of the PRF, additional laboratory and monitoring test data have been supplied by DuPont. The assessment of these studies are included in this report. Diuron is a selective herbicide for broadleaf weeds and some annual grasses. It belongs to the urea group of herbicides and is readily absorbed through the root system of plants and less readily through the leaves and stems. Residues in soil are toxic to plants. It is used in many agricultural situations, general weed control in irrigation ditches and drains and in non-agricultural areas (rights-of-way, commercial and industrial areas) and often used in combination with other herbicides such as bromacil and hexazinone.

Nídia Dana Mariano Lourenço de Almeida November, 2014 ACKNOWLEDGEMENTS In March I started my thesis project at AlgaePARC, as part of the Bioprocess Engineering group. The five months I spent in Wageningen were some of the best I had and definitely the ones when I learned more about microalgae of my life. A whole new theme, whole new people, whole new equipments (the FACS nightmare)... And the greatest supervisor to help me go through all this! Iago, thank you for the help provided during this time and for becoming more than just a supervisor: a friend. Thank you for all the conversions (usually in Portuguese, thank God!), the funny facts about Brasil and the guidance about the Netherlands, they made my work much easier. Obrigada por tudo! Also, to the other students, PhD’s, investigators, technicians, thank you for answering to all my questions and helping whenever I needed. Thank you, Dorinde, for your truly helpful advices. To the WUR, thank you for receiving me and helping with everything a student needs in a new country. I would also like to thank the financial support to AlgaePARC Research Program provided by: Ministry of Economic Affairs, Agriculture and Innovation (the Netherlands), Province of Gelderland (the Netherlands), and the companies: BASF, BioOils, Drie Wilgen Development, DSM, Exxon Mobil, GEA Westfalia Separator, Heliae, Neste Oil, Nijhuis, Paques, Cellulac, Proviron, Roquette, SABIC, Simris Alg, Staatsolie Suriname, Synthetic Genomics, TOTAL and Unilever.
