This virus, called the mimivirus, is an icosahedral virus with a dsDNA genome of 1200 kb and is so far the largest virus that has been isolated. What is the importance of Emiliania huxleyi inthe oceanic ecosystem? 2001; Haidar and Thierstein 2001).

Prepare your answer in complete sentences in your own words.Exercise #6 – Page 2 of 3Sea Urchin (Red Sea Urchin)In the search field of http://marinebio.org/search enter the term Red Sea Urchin. Thus, we are probably just looking at the tip of the iceberg when considering the diversity of algal viruses. Table 2. Jordan, in Encyclopedia of Microbiology (Third Edition), 2009. In contrast to diatoms, they do not have particularly high maximum uptake rates but tend to have significantly lower half-saturation constants for nitrate uptake compared to other functional groups (Litchman et al. questions about Emiliania huxleyi. Are Moon Jellyfish considered plankton nekton or benthos?19. (use Figure 12.25 to helpyou)(1 point)25. The wild-type coccolith-bearing (C) and mutant naked (N) cells are assumed to be diploid (n = 2); the flagellate scaly (S) cells, haploid (n = 1). Here are a fewdetails on the quiz: You will have 60 minutes to complete the quiz from the time you open it. If you chose pelagic for number 5 choose from the pelagic zones.Do some research online (use quality sources) to answer the following questions:21. One haptophyte family, the Coccolithophyceae, also has calcified scales, the coccoliths (Eikrem et al., 2016). Figure 3.5. Very large viruses, often with capsid diameters of ∼100–200 nm, can be found in surface waters. Is Emiliania huxleyi considered planktonnekton or benthos?

Furthermore, it has been suggested that some algal viruses may prevent blooms by keeping the host community in check. However, recent evidence indicates that virus-derived lipids are present in E. huxley haploid cells, indicating that the cells are actually infected. In contrast to the Prymnesiophyceae, Pavlovales are rare. Is Emiliania huxleyi considered plankton, nekton, or benthos? (1 point) 24. The calcified marine unicell, Emiliania huxleyi, is the most intensively studied member of the coccolithophorid microalgae, because (1) it is easily cultured and (2) it is the most abundant coccolithophore species in the ocean and can form massive blooms in temperate and subpolar regions, producing up to 108 cells L−1 (Taylor et al., 2017). huxleyi? Coccolithophores also appear to be good nitrate, phosphorus, and iron competitors (see Figure 3), given their parameters for uptake of and growth on these nutrients (Sunda and Huntsman 1995; Riegman et al. (use Figure 12.25 to helpyou)(1 point)25. If you chose pelagic for number 5 choose from the pelagic zones.Do some research online (use quality sources) to answer the following question:7. (1 point)23. What is the common name of Emilianiahuxleyi? The distribution patterns of diatoms and coccolithophores correspond broadly to their strategies of nutrient utilization. Noncalcerous haptophyte genera, Chrysochromulina and Prymnesium, are an important source of toxic blooms. Coccolithophores influence surface-ocean biogeochemistry by fixing a significant amount of C through photosynthesis (the biological C pump) and by releasing CO2 during coccolith formation (the carbonate counter-pump) (Rost and Riebesell, 2004). See Section 12.4 of your text for help with this but make sure your answer is specific to Pacific White-Sided dolphins.

(1 point) 23. In the green microalga Ostreococcus tauri, resistance to prasinovirus infection arises frequently in culture and in Micromonas sp. Although E. huxleyi is not necessarily a typical coccolithophore (see de Vargas et al., Chapter 12, this volume), it is an ecologically important species widely distributed in the world ocean (Iglesias-Rodriguez et al.

(function(){ s1.charset='UTF-8'; 1996). Several other features also set this virus apart from the other phycodnaviruses. Emiliania huxleyi, in particular, has received considerable attention (see de Vargas et al., Chapter 12, this volume). These viruses constitute a genetically diverse, but morphologically homogenous group of icosahedral viruses with large dsDNA genomes of approximately 100–560 kb. In all these characteristics, coccolithoviruses and other NCLDV of non-photosynthetic protists (shaded lines in Table 9.1) more closely resemble animal viruses, such as poxviruses. What are TWO adaptations of Red Sea Urchins for living in their environment?

In the case of the chloroviruses, resistance to virus infection occurs quite frequently and most of the time this is due to a change in the host receptor such that the chloroviruses are unable to attach to the host. Each of these cell types can reproduce itself asexually. In what biozone would we most likely findEmiliania huxleyi? s1.async=true; (2005); Hambly et al. The majority of haemoglobins found in the partial genetic sequences of the remaining algae also appear to fit with the 3/3 fold of M family. ScienceDirect ® is a registered trademark of Elsevier B.V.

Choose the first entryfor Red Sea Urchin8. The form of the coccoliths is very species-specific (Fig. We should note, however, that this analysis is based on a single species of coccolithophorids, Emiliania huxleyi, as there are insufficient data on relevant parameters for other coccolithophores. Figure 3.6.

In contrast to chloroviruses, phaeoviruses and prasinoviruses (see below), the large E. huxleyi virus 86 genome (Wilson et al., 2005) carries an RNA polymerase gene, suggesting that at least the virus more directly controls some of its own gene expression.

Recent work suggests that syringolipid signalling might play a role in controlling host cell death during infection (Han et al., 2006; Monier et al., 2009; Pagarete, Allen, Wilson, Kimmance, & de Vargas, 2009; reviewed in Michaelson, 2010; Bidle & Vardi, 2011).
