Inserting and removing content
From Ericross

Apologies for insert-remove-insert-remove 'ping pong'.

Material inserted then removed was from a site where copyright was not immediately obvious to me, but became apparent after checking further.

Request to author for inclusion will be submitted.

Eri.

Made some minor corrections. There are still a few things in the article that are not exactly true but not exactly false. When I become a little more familiar with wikipedia (sorry, I'm a newbie), I may do a little more work on this.

Etymology
Could someone provide some etymology about the scientific name ? It's important to give the meaning of Caenorhabditis elegans, if it is a physical and behavioural description about the animal, or if it was named after some scientist. I've seen much less important animals with the complete meaning of their scientific name. —Preceding unsigned comment added by 201.74.107.149 (talk) 19:33, 9 December 2008 (UTC)

The German version says,

"Neuer-Stab zierlich[1]"

C'monnnnnnn
C. elegans is important! This article should be 50 pages long. I request the efforts of biology students and researchers and teachers to expand this page!!


 * I'm working on it! :-) I've made the first attempt to split up the page into distinct sections.  Other plans below... Nod

What this page needs
Some ideas:
 * 1) Expand biology section and as it grows create new subsections as appropriate (e.g. nervous system, cellular differentiation, mating system etc.).  Ultimately, these could each be separate wikipedia pages
 * 2) Add information about use of RNAi in worms somewhere (model organism section)
 * 3) Rather than people add their own lab to the online resources section, there should maybe be a new page for C. elegans laboratories (I removed one lab link earlier).  With so many C. elegans labs it will get unwieldly to include them all here
 * 4) try to avoid mentioning individual genes on this page. Again the page will get too crowded if people just add one sentence about their favourite gene.  Important genes probably merit separate wikipedia pages which could all be linked from a C. elegans genes page (which in turn would be linked to the C. elegans page)
 * 5) References section should also be moved to a separate page if it gets too big, though I think that this should maybe only contain details of key papers
 * 6) I've requested (from the WormAtlas project) a high quality image of the worm to to at the top of the page...an image which doesn't have any staining.

Over the falls in a barrel
It would be interesting if this could be included, though I don't know how to include it without hurting the professional tone of the article. C. Elegans may hold the record for worst calamity survived by a complex organism.

Though, I think the record for an unprotected organism (the C. Elegans were in a petri dish in an aluminum canister) is the water bear. It's amazing what those things can survive.Tragic romance 09:29, 8 December 2006 (UTC)

WormAtlas/C. elegans II copyright
I'm far from sure if we are allowed to use their text and images without asking them for it/them each time.. However, WormAtlas states:

"Images or text created by Wormatlas may be used by individuals or organizations for non-profit educational and scientific purposes with proper acknowledgement of Wormatlas (http://www.wormatlas.org). Submitted material that appear in Wormatlas require permission from the original submitter and/or publisher prior to usage or republication."

The National Center for Biotechnology Information (link) says their info is in the public domain, but I couldn't find anything on the C. elegans II (link) site. I'm not sure if we can use their pictures too.

I'm thinking of greatly expanding the section about the nervous system (well, actually more than just the nervous system but just to begin somewhere ;)), so it would be great if I/we could incorporate their data and pictures. Marcus 13:04, 28 December 2006 (UTC)


 * I contacted Zeynep Altun at WormAtlas who gave me permission for use of the image at the top of the page. I think they would be happy to let more images be used if you sought permission. Nod 19:46, 21 January 2007 (UTC)

Nematode evolution
I added this section primarily to move the paragraph on sponge-human-worm evolution out of the genome section as it didn't really seem to belong there. I also heavily pruned and edited the aforementioned paragraph as I don't think it added much interesting information to this page. I don't think a general page on a species should get too bogged down in mentioning individual genes unless they are famously associated with that organism or play a very special role. Hopefully, others can now start adding something more substantial to this section. Estimates of divergence dates from other major organisms might be of interest. Nod 19:53, 21 January 2007 (UTC)

Nicotine
The 'laboratory uses' section now states that 'The organism has also been identified as a model for nicotine dependence as it has been found to experience the same symptoms humans experience when they quit smoking. [4]'

Such as what? Nail biting, coughing and starting fights with strangers?

The (4) article mentions 'including acute response, tolerance, withdrawal, and sensitization'. Put that in, or remove the line as a whole? —Preceding unsigned comment added by Brrrtje (talk • contribs) 14:06, 3 October 2007 (UTC)
 * I'm shocked that this problem has not been fixed after over two years. I've changed that sentence to reflect the source of the information in question. Gary (talk) 03:16, 4 January 2010 (UTC)

Proposals
I would like to expand on some topics, if I have time:


 * Strains - describe the origins of N2 and talk about the different types of strain available - natural strains and lab-indiced strains. Talk a bit about how N2 is not necessarily the same between different labs as each lab has maintaned a clone of N2 for many years now and RNASeq sequencing shows divergence between them. Description of the CGC resource and how it distributes strains.


 * Resources - both for data and biological samples: WormBase, 959 Nematodes, Worm Atlas, Leon Avery's page, CGC, any others? Worm Journal, Worm Breeders Gazette.


 * How genes are curated.


 * Nomenclature of genes, CDS, transcripts, CGC names, clones,
 * (Update : I've put in a description of the gene/CDS/transcript nomenclature in the WormBase article)

File:C elegans male.svg to appear as POTD soon
Hello! This is a note to let the editors of this article know that File:C elegans male.svg will be appearing as picture of the day on October 13, 2013. You can view and edit the POTD blurb at Template:POTD/2013-10-13. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 (talk) 22:56, 26 September 2013 (UTC)

Refs, links, etc...
I've just done a major cleanup of the references, because I had nothing to do. However, I can't decide on content, since I don't know diddly squad about nematodes or C. elegans in particular. I will say that for this article to get to GA or FA status, a good look needs to be take at the External links section, and some other things need to be addressed.


 * I noticed the section on connectome references is missing a key reference: https://www.ncbi.nlm.nih.gov/books/NBK154158/ — Preceding unsigned comment added by 173.178.65.219 (talk) 15:41, 18 March 2020 (UTC)


 * A lot of this material should be properly formatted and included in the Further reading section (e.g. the nobel lectures).
 * The EL section should be trimmed to high-relevance links and given some kind of structure that makes it easy to decide where you want to go from here.
 * Several paragraphs are very short. It feels more like a list of random facts than a structured presentation the main aspects of C. elegans.
 * Some sections, like the Evolution one are grossly underdeveloped and appear way too late in the article.
 * Genome and Research should be the last two sections.
 * "The scientific community" section is badly named and too limited in scope. It should be revamped into a sort of "scientific impact" or something, which includes the nobel prizes, the genome sequencing projects and collaborations.

Latin name
Whoever inserted the IPA pronunciation for the Latin name actually reported an American pronunciation. Although it may be hard to figure out the real Latin pronunciation, this still seems wrong. As an Italian speaker (the most direct descendant of Latin, albeit still with sound shifts) I would pronounce this differently. What is the Wikipedia policy on IPA for Latin?

Errors in gene statistics.
The current page says that C. Elegans contains 16,000 RNA genes. I am unable to find support for this statement. The edit was originally made here: https://en.wikipedia.org/w/index.php?title=Caenorhabditis_elegans&oldid=308570213 However, it links to an article citing the original number of RNA genes detected in an older survey, not the newer number. I was unable (afger some searching) to find any evidence that C. Elegans has 16,000 RNA genes (which would be pretty cool) 32.210.144.151 (talk) 23:31, 18 October 2015 (UTC)

Circadian rhythm
There's been a lot of research in recent years on circadian rhythm in C. elegans, with both light and temperature entrainment. Zyxwv99 (talk) 02:37, 20 November 2015 (UTC)

Please add monocentric chromosomal pairing photos and drawings
Please add monocentric chromosomal pairing photos and drawings. We should photograph Caenorhabditis elegans' chromosomes if possible, and of course add new paragraphs and links. — Preceding unsigned comment added by 2A02:587:410F:9100:5991:CEBC:671A:4E79 (talk) 22:38, 12 May 2016 (UTC)

Male Mating

Developmental Biology Overhaul
Because C. elegans is such an important developmental model system, I decided to seriously revamp the Reproduction and development section. I decided to split the section into two distinct sections, because, while related, a lot of the reproductive information already on the page, much of it relating to males and mating, isn't super relevant to the developmental processes that are most often studied using C. elegans as a model. While a little detailed, I feel that my edits are reasonable in terms of their accessibility to the general public, and the level of detail is reflective of nematode's importance as a developmental model system. I did some other housekeeping of the section, including moving some of the images to the anatomy section, where I thought they were more appropriate. I added largely new section on post-embryonic development, and included a figure from worm atlas with the proper citation to clarify and give some aesthetic appeal to the section. — Preceding unsigned comment added by Elegans180 (talk • contribs) 18:55, 4 January 2018 (UTC)

Subspecies
Currently, the taxobox for this species contains 'subspecies', but lists only varietas (variety) names. These names have no formal taxonomic rank in Zoological Nomenclature if they were established after 1960 (Article 45 of the Code), so at least "var. bristol" should not be deemed a subspecies, but rather as infrasubspecific, and not included under this heading. "var. Bergerac" on the other hand is older, and may warrant recognition as a subspecies under Article 45.6.4. Someone who is familiar with nematode taxonomy needs to fix this.Dr Mark D. Scherz 09:02, 22 July 2020 (UTC)

302 neurons?
This animal is listed as having 302 neurons. Is that number just for a particular individual whose connectome was studied or does it apply to the whole species? I would assume that the number of neurons in an animal is not a fixed thing for a species, even an extremely simple one like this. But maybe I'm wrong. Maybe some species are very precisely decided by their genes even at the neurological level. Jason Quinn (talk) 05:55, 26 September 2020 (UTC)

Proposed merge of Victor Nigon into Caenorhabditis elegans
