Talk:Mariannaea elegans/Archive 1

Anika's Review

Lead Section:

• Stating the it is from a genus Mariannaea is repetitive in the introduction, especially since you go over it in the taxonomy
• Try to use this space to summarize the entire article by providing readers a snippet of what’s to come. This should be done in about two or more paragraphs.
• Your last bullet point seems out of place in the lead section. You can try bringing that bullet point over to History and taxonomy.

History and taxonomy:

• I suggest removing the reference (4) since its leads to a page that does not have sufficient information.
• Otherwise, this is a well thought out sections!

Growth and morphology:

• This is very detailed!
• One ambiguous point that may need more information would be the point about it thriving at 50°C. If the optimal is 30°C for growth, and it thrives at 50°C, is there any information on that point to which it was stop growing?

Physiology

• This section could be expanded
• There is one article that I found that could be helpful. http://www.jtnrs.com/sym31/08_P-09.pdf This article looks at the production of glycophingolipids in M. elegans and how salts and sugars affect this.
• If there isn’t enough information to create a well written section, I suggest combining section so adding the bullet points to other sections where it makes sense. You don’t necessarily have to keep the Physiology heading. Check out the examples in our Wiki timeline.

Ecology:

• Interesting sections, especially about the ecological ambiguity in the last point.
• Is there specific countries where M. elegans is found? Considering it growing in warm temperature is it possible for it to be commonly found in hotter climates?
• You can also describe its growth density, and the difference in the way it grows depending on the host (wood versus house dust for example).

References:

• Remove Ref #4
• Try to see if you can get more information for ref #1.

Ningyu's peer review (xuningyu)

Hello Bela, here are my suggestions for your fungi, i hope it can help you:

• Try to make the points to a lead graph.
• You did well in the Scientific classification. The picture is very helpful for readers. Good job!
• But for Synonyms, i found that there is more you can list, here is the website: http://www.speciesfungorum.org/Names/GSDSpecies.asp?RecordID=300242

History and taxonomy

• Very detail history and taxonomy. Good to see that you talk about why they name it Mariannaea elegans.
• If there is more synonyms you can add, you can add the history of those synonyms.
• You can mention where they found it and isolated it (like a specific place and an organism). Since i could not access your third reference online, you can go to the library to get more information from the book.

Growth and Morphology

• This part is very detail. You did a good job here. Try to be logic when you transfer those points to paragraph.

Physiology

• I like that you did fully research the growth temperature and its morphology under different condition.
• Maybe what kind of substrate(as food) it likes growth with can be mentioned.
• It will be good if you mention that it is not pathogenic and do not produce any toxic substrates again.

Habitat and ecology

• Make an internal link for "amoebae", easier understanding or reader.

References

• More references will be good to state your fungi, try to find more paper or book make a strong scientific basis.
• The #4 reference looks weird, maybe you have made mistake when you cite it, please double check and correct it.

Overall, you did a great job! Since you have such detail information about this fungi, it is important to write the paragraphs in logic. Be careful with your sentence structure and your mood. Good luck in editing it!

Peer Review - Mahreen

Hi Hella, you have some really great information in this draft! Here are a few suggestions I had:

• You could add more information to your lead section. As mentioned before, since stating that it is from the genus Mariannaea seems redundant, perhaps state which division (Ascomycota) and order your fungus is in. This might provide readers with a quick understanding of the life cycle of your fungus as well as its taxonomy.
• It would also be helpful to state what your fungus does in the lead section - ie. it can decompose cellulose, so it might be involved in wood decay.
• Your history and taxonomy section is very detailed and well thought out - I like that you provide some information on why the fungus was named what it was, and why the classification has changed! There is a typing/coding error in this section under the 7th bullet point that you should fix. Your last bullet point states that it has been mistaken for other species - is there a reason why? Does it look morphologically similar to these other two species or is its habitat similar? Otherwise, great job on this section!
• The growth and morphology section also has some great details in it, especially when grown in lab conditions. It would be interesting to add what this fungus grows like in nature, as opposed to what it looks like in the lab. [This link] takes you to a patent for the control of sapstain caused by Mariannaea elegans. The patent indicates that your fungus causes a blue-grey stain on wood, and there is interest in controlling this growth using different antibiotics and antifungal metabolites. If you use the references and information found in this article, you could also expand your physiology section once you determine which metabolites worked best at inhibiting the growth of your fungus. Alternatively, you could create a different section to discuss the implications of M. elegans growth on the timber industry, and the steps taken to solve this issue!
• Something else that would be useful to add is the life cycle of your fungus - does it reproduce sexually or asexually, or both? Are there certain environmental triggers that cause it to switch from one form to the other?
• Your physiology section is sparse but provides some important information on your fungus. You mention that your fungus produces various enzymes to decompose cellulase - this would be a good space to talk about how your fungus causes soft-rot or wood decay. As mentioned above, you could rename this section entirely to talk about its effects on the wood/timber industry, or simply add that information to expand this section.
  • I also found this study that isolated a metabolite from this fungus, which inhibits platelet aggregation in humans; this might be interesting information to add to the physiology section: https://www.ncbi.nlm.nih.gov/pubmed/11302199 — Preceding unsigned comment added by MahreenK (talk • contribs) 18:00, 2 November 2018 (UTC)
• Your habitat and ecology section goes over some important information, although you definitely could add more references to this. If you look at the Mycobank page for your fungus, it will provide you with primary references of where your fungus was isolated - this could also turn into a subsection in the habitat and ecology section if your fungus has various hosts (other than Scots pine wood, which you have mentioned). I would also suggest moving your third bullet point relating on its effect on P. nameko growth to the physiology section, since this might have more to do with certain enzymes or metabolites that your fungus produces.
• You mention that your fungus has not been isolated from animals, humans or insects - it might be interesting to add in some information as to why. [This article] indicates that bacteria isolated from salamanders have anti-fungal activity, specifically against M. elegans. Perhaps other amphibians also have these bacteria, which prevents your fungus from infecting them. The [patent] I linked above demonstrated in their experiments that M. elegans failed to produce any toxic metabolites when grown in agar, and that the isolates were unable to grow at 35°C, and would therefore be unable to grow at human body temperature (37°C). This sort of information could be added into your article under the physiology section to expand it a little.
• I would suggest trying to find some more primary sources by combing through the references of the articles already referenced (including the books) because they often cite primary sources that have isolated the fungus from specific environments or hosts - this will allow you to expand on some information and create possible subsections in your article.
• Overall, you did a great job on your draft and you're on your way to writing a great wiki article!

Some suggestions

• references and formatting look OK
• Mariannaea genus is comprised of eight species --> either “The genus ‘’Mariannaea’’ comprises...” or “The genus ‘’Mariannaea’’ is composed of...”.
• watch your subject-verb agreement, e.g., “is a filamentous fungi...”
• specie's is not a word
• Did Samson really name it after his wife or did I just make that up?
• what are azonated colonies? Is there a more common language way to say that? Also terms like verrucose,
• I don’t think Zaire exists anymore, isn’t it Democratic Republic of Congo now?
• you might be able to locate more content if you check out [[[1]]] if you haven’t already
• good job so far!
