Termite gut

[tnn111]

"Termite gut P1 segment microbial communities" anyone?

Not sure how to do that one.

[pbuttigieg]

Perhaps a class like "microbiome of the termite gut's P1 segment"?

Note the this would reference the environment the communities are in (the communities are a necessary part of a biome), but not only the communities themselves.

@tnn111 I can answer your question as I'm currently working on creating envo terms for the JGI/EBI biomes.

My understanding of the terms:

root > Host-associated > Arthropoda > Digestive system > Gut > P3 segment
root > Host-associated > Arthropoda > Digestive system > Hindgut > P1 segment
root > Host-associated > Arthropoda > Digestive system > Hindgut > P3 segment

is that they must be sourced from the description given in this paper Cellulolytic Systems in Insects (Arthropoda include termites).

Where they describe the five segments of the termite hindgut (from front to back): ileum (P1), enteric valve (P2), paunch (P3), colon (P4, this region is sub-divided into P4a and P4b in some cases), andrectum (P5).

Similarly for according to this paper Internal ornamentation of the first proctodeal segment of the digestive tube of Syntermitinae (Isoptera, Termitidae) in a logical extension of whats described in the other paper those 5 segments are refereed to as proctodeal segments which gives us the root > Host-associated > Arthropoda > Digestive system > Gut > Proctodeal segment

Also I think the Gut > P3 segment and Hindgut > P3 segment refer to the same thing.

Thanks @kaiiam - so you'll be able to create the ENVO class for this region?
I think we should go for an informative name like "termite ileum microbiome" with a synonym like "microbiome of the P1 segment of the termite gut"

Does UBERON have a relevant class for this anatomical entity?

[tnn111]

Thanks. It’d be nice to have classes for this. Do all Arthropoda have the P1 and P3 segments? I’m going through a lot of these annotations to get a better idea of what is there and that is one I can’t find a good answer for in ENVO as it is now.

seems like the actual microbial community should be in PCO?

Keep the requests coming! We'll often have to import semantics from other interoperating ontologies to make sure things fit. ENVO grows based on user needs.

@tnn111

Do all Arthropoda have the P1 and P3 segments?

I'm not sure, but by having a class such as @pbuttigieg is suggesting termite ileum microbiome be subclass to arthropoda digestive system associated microbiome we cover these cases without stating all Arthropoda have the P1 and P3 segments.

If necessary classes such as arthropoda ileum microbiome could be created later.

Uberon has ileum, however I cannot find classes for paunch or Proctodeal segment. paunch is a related_synonym in rumen but that refers to the rumen of a ruminant animal. So I don't think this class is appropriate for termites. I'll add these to my list of UBERON requests.

[pbuttigieg]

Thanks @kaiiam, could you cross-link the issues on the UBERON tracker to this issue?

[cmungall]

If you add a ticket in uberon I will take care of it.

Didn't realize we were making "X microbiome" classes?

@cmungall Thanks! I have several uberon issue to post, I will post all of them and as @pbuttigieg suggest cross link accordingly.

Didn't realize we were making "X microbiome" classes?

@cmungall I though this was the general plan which we'd discussed this in our previous email exchanges recall the example I gave the example of a microbiome term:

marine abyssal plain microbiome

Definition:

An oceanic microbiome which is determined by an abyssal plain.
