February 1st, 2007

Jen Clark, David Hill, Midori Harris, Jane Lomax (8:00am EST- 12:55pm EST)

Strategy ideas:

  1. Maybe we should do all the cell component terms first. Then we can do all other terms that are differentiated by those components.


To do:

  1. Midori to check if peptidoglycans are in cell walls of fungi and to see if there are any that don't have chitin. DONE!
  2. Jen will clean up the plant cell wall terms to indicate that they both contain pectin.
  3. Change cell wall biosynthetic processes to reflect assembly and metabolism. Jane will look into this.
  4. Have Becky confirm that it is ok to change insect aorta to dorsal vessel aorta.(YES)
  5. Is it o.k to say insect appendage development? It is really the only way to distinguish this term. Perhaps we can distinguish *

wings in a more stuctural way. Perhaps arthropod appendage develoment. Exoskeleton-containing appendage development.

  1. We need to rearrange wing development. Q: Does a wing have an exoskeleton?
  2. Check ATP synthesis coupled proton transport in bacteria vs eukaryotes.
  3. Check the pubmed ID from spore wall assembly to (GO:0030476) to get at good defs for the spore wall component terms (Midori).
  4. Ask Michelle about the difference between the eukaryotic and prokaryotic ATP transporters.
  5. As for bacterial capsule, could it be referred to as a semisolid-capsule or gelatious capsule? There is a problem distinguishing this term from its sib which is slime layer. Also need to distinguish it from the fungal capsule. Michelle.
  6. Ask Tanya about the cell surface sensu Magnoliophyta terms. How are they really different from the generic cell surface parent. If not, can we just merge and add a new part of term external side of cell wall.
From meeting minutes, Cambridge, Sept. 2002:
"Cell surface" and related terms: these were added recently by TAIR curators, to capture information from experiments in plants that can narrow down localization to plasma membrane or cell wall but can't distinguish between the two (that's what's meant by "cell surface" in plant literature). The definitions and placement of the cell surface terms were discussed, and changes recommended.
action item 25: TAIR curators to improve definitions of "cell surface" and its children.
    1. Action item: Tanya to review old SF items for cell surface and implement changes suggested if deemed appropriate. Changes suggested are: [DONE 2-20-2007]
      1. merge cell surface and cell surface(s. M.)
      2. create new term 'external side of cell wall' as a part_of child of cell surface
      3. make new term above and is_a child of cell wall part
      4. make 'longitudinal side of cell surface' an is_a child of cell part and remove (s. M.) from main term string (retain as synonym?) leave as part_of child of cell surface
      5. make 'external side of plasma membrane' and is_a child of plasma membrane part
  1. Note that we are using logical "or" in definitions and term names. Make sure this is in the web documentation somewhere.

February 6, 2007

David Hill, Jane Lomax, Jen Clark, Midori Harris (intermittently) 9:30EST-12:30EST


Strategy
Do the cellular component terms first.

Dealt with

  • cortical microtubules
  • DNA-dependent RNA polymerase, cytosolic, nuclear and plastid
  • Rearranged the thylakoids and their children quite a bit.
  • Did pyruvate dehydrogenases. Made the bacterial one cytosolic.


Action Items:

  1. Do we really need archaebacterial and bacterial cytosolic ribosomes? Ask Harold about how to distinguish these.
  2. Can we obsolete spore wall (sensu Fungi) and make 2 new terms, one to describe the 2-layered pombe and one describing the 4-layered one in cerevisiae. Inform Val et al.
  3. Ask tanya if she is happy with lignin containing spore wall and cellulose containing cell wall.
    1. I consulted with our biochemists and plant primary cell walls have cellulose and pectin while the secondary cell walls have cellulose and lignin. I'm happy with cellulose and pectin-containing cell wall, which is the way you have it now. Do fungal spore walls also have cellulose and pectin? [TB 2-20-07]
  4. Ask Kimberly what the C. elegans dosage compensation complex is composed of. Is it just protein?

February 7, 2007

Jen Clark, Jane Lomax, David Hill
Strategy

Continue with the component terms.

Dealt with:

  • Changed names of light-harvesting complex sensu terms (ProteoBacteria and Viridiplantae) to plasma membrane light-harversting complex and chloroplast light-harvesting complex
  • proton-transporting ATP synthase complex (sensu Bacteria) -> plasma membrane proton-transporting ATP synthase complex

proton-transporting ATP synthase complex (sensu Eukaryota) -> mitochondrial proton-transporting ATP synthase complex and the same for all child terms

  • When something is in the mitochondrion and in a bacterium, we made the bacterial one cytosolic rather than cytoplasmic to avoid a logical problem with the mitochondrion being a part of the cytoplasm.
  • Renamed and sorted out flagellum terms.



Action items:

  • Ask Michelle to join one of these meetings next week (David)
  • Ask Val to look at the gamma-tubulin terms and then meet by Skype webex (David)
  • Ask Val and Michelle if they can distinguish between the forespore of pombe and the forespore of a bacterium (David)
  • Look into the plasma membrane thylakoid and see exactly what this is. Is it a part of the membrane or is it a vesicle attached to the membrane? (Jen)
  • Get Tanya to deal with the cell surface terms. [DONE! 2-20-2007]

February 8, 2007

David Hill, Jen Clark, Jane Lomax, Michelle Gwinn-Giglio


Strategy

With Michelle's help try to tackle some of the harder proaryote terms.

Accomplished

  • several terms where locations were in organelles in eukaryotes vs plasma membrane in prokaryotes.

Action Items

  • Michelle to look into capsules and glycocalyx.
  • Jen to look into reaction center as she works through thylakoid.
  • Michelle to look into the periplasmic spaces and what we can call cell-wall bound vs. membrane bound.

Ferbruary 9, 2007

Strategy

David Hill, Jane Lomax, Jen Clark, Val Wood (intermittently)

Accomplished

  • Val came and helped with the gamma tubulin terms and the prospore/forespore.We did some major rearrangements with the gamma tubulin terms.

Action Items

  • David to look back into eye development and see if we can tidy up the fish vs. mammalian terms.
  • Ask Becky if we can have imaginal disc-derived appendage.(YES)
  • Pombe does not have chitin in its cell wall. We need a term that differentiates the fungal cell wall from the others (plant and bacterial)


February 13, 2007

David Hill, Jane Lomax, Jen Clark, Becky Foulger
1.5hrs

Strategy

  • Try to work on the fly terms.
  • Take care of appendage terms by making them imaginal disc-derived appendages. Clean all terms up.

Action Items

  • Jane to look at dosage compensation complex (assembly) terms. (DONE)
  • Make a generic wing development term to cover non-insect wings.(Jane)
  • Becky to find a distinguishing feature of optic placode in flies.

February 15,2007

David Hill, Jane Lomax, Jane Clark

Strategy

  • Take care of the eye terms from vertebrates
  • Take care of the thylakoid terms

Action Items

  • Merged the vertebrate terms. There actually is very little difference in mammals and vertebrates.
  • Should cone cell be is_a eye photoreceptor cell differentaiton?(NO, the Drosophila cone cell is not a photoreceptor)
  • Create the correct phycobilosome graph and make different types for cyanelle and plasma membrane derived. (Jen)
  • Look at thylakoid while you are on the subject. (Jen)

February 21,2007

David Hill, Jane Lomax, Jen Clark, Susan Tweedie, Becky Folger

Strategy

  • Work on more fly terms.
  • Work on embryonic development terms.
  • Work on fly tracheal terms
  • Work on fly male mating behavior terms

Action Items

  • We need to redo all the changes from the 15th. For some reson they did not commit.(done by Jen)
  • e-mail Kimberly about the cuticle terms we would like to change these terms to cuticle formation or cuticle biolgenesis and would like to know if there are clear differences between worm cuticle biogenesis and insect cuticle biogenesis. Same for ecdysis. (structural or process) Yes, there is a clear structural difference. Insect cuticles are chitin-based and worm ones are collage and cuticulin based.(Kimberly)
  • Susan to contact drosophila folks to see if physical orientation is a real male courtship behavior. Emailed Kevin O'Dell (Glasgow) 02/22/07.

February 27,2007

David Hill, Jen Clark, Jane Lomax,

Strategy

  • Work on the cuticle stuff.
  • Finish eye stuff, cone cells still need to finish photoreceptors.

To Do

  • Jane to change parentage of cuticle biogenesis. (DONE)

March 1,2007

David Hill, Jen Clark, Jane Lomax (With Becky and Michelle for specific questions.)

Strategy

  • Have a look at the ABC transporters again. May need to reconsider these.
  • Have a look at the cell walls again.

To Do

  • Jen will send an e-mail about annotations to ABC transporters. She will ask people not to move their annotations if they have not moved yet.
  • Jane will send an e-mail to Val about cell walls. We will propose a plan to have a new fungal term to include mannoproteins and glucans and then the existing term and a non-chitin containing term.
  • Jane will finish the cell wall biogenesis terms. (DONE)

March 6,2007

David Hill, Jane Lomax, Jen Clark

Done

  • Fertilization terms.
  • Made a decision on ABC transporter complex. We will keep the merge in place and make two new types, the substrate binding kind and the integrated kind.
  • Merged some of the senescence terms.
  • Changed vacuole terms to reflect the definitions. Plant has no morph change associated with cell cycle and fugal one does.
  • Cuticles are completely done. Differentiated by composition.

To Do

  • Write a sourceforge item on the bacterial vs. eukaryotic chromosomes.(David)
  • Propose the ABC transporter solution terms in SF.Check the synonyms.(Jane)
  • Have a look at modifying the defs fo the dosage compensation complexes.(Jane)
  • Jen and Tanya will look at gamete generation and gametophyte development in plants.(Jen)
  • Try to get Becky for Thursday (Jen).
  • Try to get Michelle and Pascale for the fruiting body terms (Jen).

March 8,2007

David Hill, Becky Foulger, Jen Clark

Done

  • Worked on lots of insect terms with Becky.
    • Merged eptithelial cell differentaiton
    • Renamed gastrulation terms
    • Renamed insect larval terms and pupal terms. Instar larvae and pupa(pupa is only in insect).

To Do

  • Vertebrate gastrulation terms (David)
  • Do we want to obsolete the insect metamorphosis term and split it into two, complete and incomplete? Becky will look at what amphibian larvae are called.
  • Contact Kimberly that they have a gene annotated under pole plasm assembly which is an insect term.
  • Need to come up with a distinguishing feature of the insect chorion and vitelline membrane.(Becky and Susan)
  • Jen will have a look at trichome morphogenesis (sensu magnoliophyta). Right now it is always a part of a leaf. (Jen and Tanya).
