New Look to the SourceForge Tracker
- Differences we have noticed so far:
- Emails that come to your mailbox appear to be coming directly from the submitter, with a SF address and contain the original post below, but not all the other comments. You may have to adjust your filter settings: e.g. lauramooray@users.sf.net
- On the tracker site, topics in the trackers are now oldest to newest at the bottom. Scroll down to see the most recent and add a comment.
- No easy way to get back to the main page now, (that we have found)
- New feature- sort by last updated, (but not sure if this is working correctly)
- For the average users, it should not be too different
- If you are opening new trackers the groups are now called "milestones"
- We are sorting out a few administrative details such as how to reopen or close and assign trackers. It appears that the user permissions have changed. Currently LC is a developer- probably should be an admin in order to manage trackers. Need to add Brian as developer.
- Currently, we cannot make links to new SF trackers in the browser, JE and LC are working on how to do it
- If cROP goes forward, we may want to move all our trackers to a common platform that we have more control over?
Request from GO: make protoxylem and metaxylem part_of xylem rather than is_a xylem?
Text from TB on SF:
"While trying to align the GO terms for xylem/metaxylem/protoxylem development with the PO, we encountered a difference which we hope to clarify."
(copying Chris M's summary of the situation)
When GO talks of xylem development, it means development of the 4D entirety, meaning a developmental partonomy for the parts of the xylem:
- GO:0010089 ! xylem development: The formation of the principal water-conducting tissue of a vascular plant.
<-- part_of GO:0090058 ! metaxylem development: The process whose specific outcome is the progression of the metaxylem over time, from its formation to the mature structure. The metaxylem is the part of the primary xylem that differentiates after the protoxylem and before the secondary xylem, if any of the latter is formed.
<--- part_of GO:0090059 ! protoxylem development [DEF: "The process whose specific outcome is the progression of the protoxylem over time, from its formation to the mature structure. The protoxylem comprises the first formed elements of the primary xylem.
In PO, represents these structures in a subclass hierarchy:
PO:0009007 ! portion of plant tissue: A plant structure (PO:0009011) that consists predominantly of similarly specialized plant cells (PO:0009002) of one or more types.
<-- is_a PO:0009015 ! portion of vascular tissue: "A portion of plant tissue (PO:0009007) that has as parts tracheary elements (PO:0000290) or sieve elements (PO:0025406).
<-- is_a PO:0005352 ! xylem: "A portion of vascular tissue (PO:0009015) that has as parts tracheary elements (PO:0000290).
<-- is_a PO:0005849 ! primary xylem: "A portion of xylem (PO:0005352) tissue that develops from the procambium (PO:0025275).
<-- is_a PO:0000272 ! protoxylem: A portion of primary xylem (PO:0005849) tissue that has as parts tracheary elements (PO:0000290) with only annular or helical secondary wall thickening that are the first formed tracheary elements (PO:0000290) at a particular location."
<-- is_a PO:0000372 ! metaxylem: A portion of primary xylem (PO:0005849) tissue that develops after the vascular tissue (PO:0009015) has stopped elongating and after the protoxylem (PO:0000272).
This gives us an inferred subclass hierarchy for development.
Summary: GO = inferred part_of relationship between protoxylem/metaxylem and xylem, PO = is_a relationship between protoxylem/metaxylem and (primary) xylem
Could the relationship between (protoxylem and metaxylem) and primary xylem be part_of instead of is_a?
Proposed Solution:
- Made protoxylem and metaxylem children of portion of vascular tissue and part_of primary xylem
- Could not make primary xylem tracheary element part of the protoxylem and metaxylem, created a cycle
- Created two new terms to describe the tracheary elements in the primary xylem
- Revised the definitions of protoxylem and metaxylem- incorporating the reference to the new terms
Link to tracker: primary xylem tracheary element terms:
- primary xylem tracheary element (PO:0025444): A tracheary element (PO:0000290) that is part of a portion of primary xylem tissue (PO:0005849).
- protoxylem tracheary element (new PO:0025575): A primary xylem tracheary element (PO:0025444) with predominately annular or helical secondary wall thickening that are the first formed tracheary elements (PO:0000290) at a particular location.
Comment: In a given portion of primary xylem (PO:0005849), protoxylem tracheary elements are generally smaller in size, fewer in number and have less secondary wall material than metaxylem tracheary elements (PO:0025576).
- metaxylem tracheary element (new PO:0025576): A primary xylem tracheary element (PO:0025444) that may have helical, scalariform, reticulate and/or pitted secondary wall thickening.
Comment:In a given portion of primary xylem (PO:0005849), metaxylem tracheary elements are generally larger in size, greater in number and have more secondary wall material than protoxylem tracheary elements (PO:0025575).
See also notes on POC_Conf._Call_4-23-13, additional children of protoxylem added recently. These are not affected
Issues:
- xylem vessel PO:0025417: A portion of xylem (PO:0005352) tissue that has as parts a tube-like series of vessel members (PO:0002003), the common walls of which have perforations.
This sound probably be handled in a similar way- make it a portion of vascular tissue, part of xylem.
- Need to look at the developmental stages for primary and
- secondary xylem development stage PO:0025427
