SIA v0.2.1 Released
Note the update to v0.2.1 already. I solved a nagging issue and enhanced the data storage structure today. If you downloaded v0.2 yesterday, please upgrade to v0.2.1 before continuing to try out SIA. Thanks! - JP
Justin Preece has packaged and uploaded a new version of SIA for Mac and Linux (Windows still in progress). This version is fit for public consumption, although it is still very much beta software with lots of opportunity for improvement. Several technical issues have been fixed and a few small enhancements have been made.
- Our lab site post: http://jaiswallab.cgrb.oregonstate.edu/software#SIA
- Downloads: http://files.cgrb.oregonstate.edu/Jaiswal_Lab/sia/v0.2.1/
It would be great if folks on today's call with access to Linux and Mac machines could give the installation instructions a test drive. Feel free to let me know if anything seems amiss. If you want to report any bugs or request new features, just send an email to <sia-support@palea.cgrb.oregonstate.edu>
JP will coordinate the appropriate PO emails and web site announcements with Lol. Thanks!
Update from Cornell
Ale has been in communication with Bob Turgeon and got comments from him on phloem terms. Still waiting for follow up. MAG will forward the information.
Manuscripts in prep
No discussion today
Change to gametophyte development stage
This change is urgent, because we need to address this in the manuscript in prep.
gametophyte development stage (PO:0028003) is currently defined as "A whole plant development stage that has as primary participant a whole plant during the interval between meiosis or apospory and its death or fertilization."
I think the last part about fertilization is misleading, because it suggests that the gametophyte stage could end in any plant with fertilization. Many gametophytic plants continue to live (and nourish the sporophyte) long after fertilization. In seed plants, the gametophyte does not exactly die after fertilization, but is transformed. I suggest we add something to the comment to help explain this, but keep the definition simpler.
New proposed definition: A whole plant development stage (PO:0007033) that has as primary participant a whole plant (PO:0000003) during the interval between meiosis or apospory and its death.
New addition to comment (rest stays the same): In seed plants, the gametophyte may be transformed by fertilization but not strictly die, such as when pollen (PO:0025281) germinates or when a plant embryo (PO:0009009) begins to develop within an embryo sac (PO:0025074) of an angiosperms.
After some discussion, we thought probably the best way would be to define the gds as ending when the gametophyte ceases to exist. Comment: ceasing to exist can either come about by death, at any point, or transformation, through fertilization.
Better to say "when pollen releases its sperm cells" than when it germinates. Germination of pollen is still in the gametophyte stage.
Fruit development stages for whole plants
whole plant fruit development stage (PO:0025500)
New term
proposed defintion: A sporophyte reproductive stage that begins when a single fruit (PO:0009001) enters its fruit initiation stage (PO:0025503) on a whole plant (PO:0000003) that does not have any other fruits as part, and ends with the earliest of the following: (1) the whole plant begins a sporophyte senescent stage (PO:0007017), (2) the whole plant begins a sporophyte dormant stage (PO:0007132), or (3) all fruits on the whole plant are finished ripening.
Comment: Sub-classes include whole plant fruit formation stage (PO:0007042) and whole plant fruit ripening stage (PO:0007010). An iteroparous plant will have a single whole plant fruit development stage during its life of whole plant (PO:0025337), while a semelparous plant may have multiple whole plant fruit development stages during its life, each of which will be part of the same instance of a sporophyte reproductive stage.
It doesn't work to say "it has not other fruits as part", because sometimes the fruits from the previous fruiting cycle are still present. Also, sounds like there is only one fruit made by the plant.
PJ suggested creating instead a "whole plant fruit bearing stage", but the problem with that is that many plants have fruits long after they leave the sporophyte reproductive stage. We could have such a stage, but it could not be a sub-class of sporophyte reproductive stage. It would have to sit outside our existing classification.
We decided to work on the individual fruit stages first then come back to the whole plant stages.

postponed to future meeting
New fruit development stages
fruit development stage (PO:0001002)
def.: A plant structure development stage (PO:0009012) that has as primary participant a single fruit (PO:0009001).
comment: Defined by characteristic morphological, structural, histological or other visible features of a fruit. May have as part a seed development stage (PO:0001170). This stage applies to an individual fruit (PO:0009001). For development stages of a whole plant based on fruit development, use whole plant fruit development stage (PO:0025500) or its subclasses.
okay
New proposed subclasses
still need to create SF tracker items and add xref to terms
carried over to next week
fruit formation stage (PO:0025501)
Proposed def.: A fruit development stage (PO:0001002) that being with the formation of the plant zygote (PO:0000423) that is contained in that fruit and ends when its fruit ripening stage (PO:0025502) begins.
comment: A fruit formation stage may begin without fertilization or formation of a zygote in cases of parthenocarpy, apomixis, or other hormone-induced conditions. This stage applies to an individual fruit (PO:0009001). For the development stage of a whole plant (PO:0000003), use whole plant fruit formation stage (PO:0007042).
new subclasses of fruit formation stage
These are the stages that were developed for whole plants, but groups like SGN really need to apply them to individual fruits. I also added a new stage for fruit initiation.
fruit initiation stage (PO:0025503): A fruit formation stage (PO:0025501) that begins with the formation of the plant zygote (PO:0000423) that is contained in that fruit (PO:0009001) and ends when the plant cells (PO:0009002) in the fruit begin to divide or expand (add GO terms).
Comment: The fruit initiation stage may begin without fertilization or formation of a zygote in cases of parthenocarpy, apomixis, or other hormone-induced conditions. This stage ends as soon as plant cells (PO:0009002) in a developing fruit begin to divide or expand. This stage is to be used for an individual fruit. For the development stage of a whole plant (PO:0000003), use whole plant fruit formation stage up to 10% (PO:0007032).
What about fruits that don't grow after fertilization? I guess they go right to ripening stage? Do we need a comment to this effect? Maybe say it ends when cells start to divide or expand or senesce, if it goes directly into the ripening stage.
Note that this stage could be very brief, if fruit starts to grow or ripen right away.
We need to coordinate with go about terms like "growth".
fruit size up to 10% stage (PO:0025504): A fruit formation stage (PO:0025501) that begins after a fruit initiation stage (PO:0025503), and ends when the fruit (PO:0009001) has reached 10% of its final size.
Comment: Begins as soon as plant cells (PO:0009002) in a developing fruit begin to divide or expand. Succeeds a fruit initiation stage (PO:0025503) and proceeds a fruit size 10 to 30% stage (PO:0025505). This term can only be used if the final size of the fruit is known. This stage is to be used for an individual fruit. For the development stage of a whole plant (PO:0000003), use whole plant fruit formation stage up to 10% (PO:0007032).
fruit size 10 to 30% stage (PO:0025505): A fruit formation stage (PO:0025501) that spans the interval when a fruit (PO:0009001) has reached 10% to 30% of its final size.
Comment: Succeeds a fruit size up to 10% stage (PO:0025504) and proceeds a fruit size 30 to 50% stage (PO:0025506). This term can only be used if the final size of the fruit is known. This stage is to be used for an individual fruit. For the development stage of a whole plant (PO:0000003), use whole plant fruit formation stage 10 to 30% (PO:0007009).
fruit size 30 to 50% stage (PO:0025506): A fruit formation stage (PO:0025501) that spans the interval when a fruit (PO:0009001) has reached 30 to 50% of its final size.
Comment: Succeeds a fruit size 10 to 30% stage (PO:0025505) and proceeds a fruit size 50 to 70% stage (PO:0025507). This term can only be used if the final size of the fruit is known. This stage is to be used for an individual fruit. For the development stage of a whole plant (PO:0000003), use whole plant fruit formation stage 30 to 50% (PO:0007029).
fruit size 50 to 70% stage (PO:0025507): A fruit formation stage (PO:0025501) that spans the interval when a fruit (PO:0009001) has reached 50 to 70% of its final size.
Comment: Succeeds a fruit size 30 to 50% stage (PO:0025505) and proceeds a fruit size 70% to final size stage (PO:0025508). This term can only be used if the final size of the fruit is known. This stage is to be used for an individual fruit. For the development stage of a whole plant (PO:0000003), use whole plant fruit formation stage 50 to 70% (PO:0007007).
fruit size 70% to final size stage (PO:0025508): A fruit formation stage (PO:0025501) that spans begins when a fruit (PO:0009001) has reached 70% of its final size and ends when a fruit has reached its final size and a fruit ripening stage (PO:0025502) begins.
Comment: Succeeds a fruit size 50 to 70% stage (PO:0025507) and proceeds a fruit ripening stage. This term can only be used if the final size of the fruit is known. This stage is to be used for an individual fruit. For the development stage of a whole plant (PO:0000003), use whole plant fruit formation stage 70% to final size (PO:0007027).

possible venue for CROP white paper?
PRO-PO-GO meeting, May 2013
Location: Buffalo, NY
Tentative Dates: May 8-9th or May 15-16th, 2013.
Goals:
- To educate members of the PRO, PO and GO communities concerning developments in each of the three ontologies, with a view to enhanced coordination
- To identify potentially fruitful applications which such enhanced coordination might bring
- To enhance the Protein Ontology treatment of plant-related proteins
- To address coordination issues between the GO and PO, for example as concerns treatment of development stages
- To further those aspects of CROP which relate to PRO and GO [this is assuming that PRO is included as one of the external ontologies in CROP]
Tentative participant list:
PO Consortium members: Pankaj Jaiswal and Laurel Cooper (OSU), Dennis Stevenson (NYBG), Barry Smith (Buffalo), others?
GO Consortium members: Jane Lomax (EBI), Judith Blake (JAX), Alex Diehl (Buffalo) who else?
