Talk:Centrosome

message: the last section highlights the research by alliegro et al. on centrosome-associated rna in clam oocytes. to my knowledge, this has not been confirmed and also has been put into doubt in the paper itself. the reason of the rna appearing could be a parasite/viral infection. i think that there are many more interesting developments regarding e.g. centrosome duplication, breast cancer susceptibility and centrosome dysfunction, centrosomal clustering etc. that are worth mentioning.--Raineruu 13:53, 23 October 2007 (UTC)

message: They have centrosomes, but not centrioles, and I'm certain of this.   "Since by definition the centrosome is made of centrioles surrounded by pericentriolar material" is a wrong definition which you are afraid to site its source.  Sentriclecub (talk) 01:20, 23 January 2008 (UTC)
replies: text: No, higher plants do not have centrosomes. See any modern botany textbook on this. It is one of the often-cited differences between plant and animal cells. Flagellated green algae and some lower plants that make flagellated sperm cells still have centrioles though and some green algae use centrosomes/basal bodies during mitosis to organize the spindle. - tameeria (talk) 13:38, 23 January 2008 (UTC)
replies: text: Okay, I believe you fully.  I was frustrated that someone used a circular logic and used the wikipedia article itself to assert that plants don't fit the criteria for having centrosomes.  My source was my 2003 bio textbook and MCAT prep-materials.  Makes you wonder about this subset of scientists.  The biology articles on WP aren't as accurate as physics and chemistry, I've noticed.  That's just my opinion though. Sentriclecub (talk) 11:54, 3 February 2008 (UTC)
replies: text: There seems to be some confusion about this and plenty of websites stating that plants have centrosomes. I'm not sure where this misinformation is coming from, but my textbooks (college level) all disagree and if I do a search for plant + centrosome on PubMed recent research and review papers regarding plants state things like: "In acentriolar higher plant cells, the surface of the nucleus acts as a microtubule-organizing center, substituting for the centrosome." - "Flowering plants, lacking centrosomes as well as dynein, assemble their mitotic spindle via a pathway that is distinct visually and molecularly from that of animals and yeast." - "Plant cell cortical microtubule arrays attain a high degree of order without the benefit of an organizing center such as a centrosome." I suspect the idea that plant cells must have centrosomes stems from an outdated animal-centric view and trying to apply what is found in animal cells to plant cells by analogy, which in this case is not correct. - tameeria (talk) 14:29, 3 February 2008 (UTC)
thread_title:  Plant cells do have centrosomes? 

message: This article states the centrosome was discovered by Boveri in 1888. I found several other sources stating that it was first described by Walther Flemming in 1875 and Edouard Van Beneden in 1876, some sources even saying it was discovered by Flemming already around 1870. It seems different sources credit either Flemming, Van Beneden, or Boveri with the "discovery" but it appears Boveri was the first to name the structure "centrosome." Therefore, shouldn't Flemming be credited with the discovery and Boveri with the naming then? Is there a reference for the statement currently in the article? - tameeria (talk) 15:53, 3 February 2008 (UTC)
thread_title:  Discovery - who and when? 

message: It says in the articel:
"Some cell types arrest in the following cell cycle when centrosomes are absent. This is not a universal phenomenon."
but it doesn't say what cell cycle??  —Preceding unsigned comment added by 132.216.43.208 (talk) 13:00, 10 October 2008 (UTC)

message: No size is given for the centrosome in the article. Would be nice to have that added. Dietzel65 (talk) 11:04, 9 March 2016 (UTC)
thread_title:  Size of the centrosome? 

message: The section on the evolution of the centrosome is based on an old view of the evolutionary tree of eukayotes. As far as I know, current view does not place Giardia as an early branch.
See, for example,  http://www.nature.com/nature/journal/v440/n7084/full/nature04546.html  — Preceding unsigned comment added by 192.12.12.234 (talk) 16:42, 11 August 2016 (UTC)
