New fruit development stages for individual fruits
Last week we agreed to add a term for fruit development stage (PO:0001002).
New proposed subclasses
fruit formation stage (PO:0025501)
We worked on this term a bit last week. Here is a modified definition, based on our discussion.
Proposed def.: A fruit development stage (PO:0001002) that begins with the formation of a plant zygote (PO:0000423) that is contained in the fruit (PO:0009001) being studied and ends when that fruit's 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. 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 similar to the stages that were developed for whole plants, but groups like SGN really need to apply them to individual fruits. Includes a new stage for fruit initiation, which is probably not needed for whole plants.
fruit initiation stage (PO:0025503): A fruit formation stage (PO:0025501) that begins with the formation of a plant zygote (PO:0000423) that is contained in the fruit (PO:0009001) being studied and ends when the plant cells (PO:0009002) in the fruit begin to divide or expand.
Comment: The fruit initiation stage may begin without fertilization or formation of a plant zygote (PO:0000423) 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 and may be very brief. 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 can go directly into the ripening stage.
Note from last week: 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 when the plant cells (PO:0009002) in a fruit (PO:0009001) begin to divide or expand, and ends when the fruit has reached 10% of its final size.
Comment: 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).
fruit ripening stage
Proposed def.: A fruit development stage (PO:0001002) during which a fruit (PO:0009001) participates in the process of fruit ripening (GO:0009835).
Comment: Succeeds a fruit formation stage (PO:0025501). This stage is to be used for an individual fruit. For the development stage of a whole plant (PO:0000003), use whole plant fruit ripening stage (PO:0007010).
Link to GO page for fruit ripening. Note that we already worked on this term with GO.
Note that I have not yet proposed any subclasses for this term. Also, I have not yet addressed development stages for any of the parts of fruits, such as pericarp, which could be used to help define more specific stages for the ripening of the whole fruit.
The subclasses for whole plant fruit ripening stages are very vague and have circular definitions. Suggest that PO work on stages of individual fruit ripening and then tackle the whole plant stages.
Fruit development stages for whole plants
whole plant fruit development stage (PO:0025500)
New term
Continued from POC Conf. Call 10-9-12
proposed defintion: A sporophyte reproductive stage that begins when a 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: Includes 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.
whole plant fruit formation stage (PO:0007042)
New proposed def.: A whole plant fruit development stage (PO:0025500) that begins when the first fruit (PO:0009001) on a whole plant (PO:0000003) that has no other fruits as part enters a fruit initiation stage (PO:0025503) and ends with the onset of a whole plant fruit ripening stage (PO:0007010).
Comment: This term is to be used for a stage of development of a whole plant (PO:0000003). For the stages of development of an individual fruit, see fruit development stage (PO:0001002). An iteroparous plant will only have one fruit formation stage in its life, while a semelparous plant may have multiple whole plant fruit development stages during its life. In plants with continuous (i.e., indeterminate) fruit development (GO:0010154), new fruits may continue to develop after the first fruit has begun to ripen and the fruit ripening stage of whole plant (PO:0007042) has begun. Although the use of synonyms like 07-milk stage in rice properly refer to the development of an individual fruits, they are used as here to extrapolate to a whole plant.
Is it better to use whole plant fruit formation stage has_part fruit formation stage (new term, see below) or fruit formation stage part_of whole plant fruit formation stage?? Haven't added either yet. Ideally, we could add both, but AmiGO can't handle it.
Subclasses of whole plant fruit formation stage (PO:0007042)
On next week's agenda: POC_Conf._Call_10-23-12#Subclasses_of_whole_plant_fruit_formation_stage_.28PO:0007042.29
whole plant fruit ripening stage (PO:0007010)
New proposed def.: A whole plant fruit development stage (PO:0025500) that begins when the first fruit (PO:0009001) on a whole plant (PO:0000003) begins the process of ripening (GO:0009835) in a way which, in case there are other fruits, the majority of the other fruits start to ripen continuously therewith, and ends with 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: Succeeds a whole plant fruit formation stage. This term is to be used for a stage of development of a whole plant. For the stages of development of an individual fruit, see fruit ripening stage (PO:0025502). Although individual fruits are undergoing ripening (which is a type of senescence) during this stage, the whole plant is not yet undergoing multicelluar organism senescence (GO:0010259). An iteroparous species generally will have only one fruit ripening stage in its life, followed by a sporophyte senescent stage (PO:0007017), as in case (1). A semelparous species may have one fruit ripening stage for each whole plant fruit developments stage (PO:0025500), followed by a sporophyte dormant stage (PO:0007132), as in case (2). In evergreen species, a plant may have multiple fruit development stages and in the sporophyte reproductive stage (PO:0007130) after all fruit has ripened, without entering dormancy or senescence, as in case (3). In plants with continuous (i.e., indeterminate) fruit development (GO:0010154), new fruits may continue to develop after the first fruit has begun to ripen and the whole plant fruit formation stage (PO:0007042) has ended. In some plants, fruit may continue to ripen after the whole plant has entered a sporophyte dormant stage or sporophyte senescent stage and left the whole plant fruit ripening stage. Some plants may never enter a whole plant fruit ripening stage, because fruits only begin to ripen after the plant has entered a sporophyte dormant stage or sporophyte senescent stage. Although the use of stages like dough stage properly refer to the development of an individual fruit, they are used as here to extrapolate to a whole plant.
Is it better to add whole plant fruit ripening stage has_part fruit ripening stage or fruit ripening stage has_part whole plant fruit ripening stage? Haven't added either yet. Ideally, we could add both, but AmiGO can't handle it.

We will be running a workshop focusing on:
Applications of Ontologies for Plant and Animal Genomics
Three speakers so far: Eva, Reinhard Simon and Elizabeth Arnaud.
- PJ present the Ref Plant Ontology Vision?
- Would like to invite someone from Textpresso and AgriGO as these are applications that would attract a number of people.
from 9/4- PJ: Suggestions- someone from GO in Berkeley, e.g. Nigam Shaw
- Can we offer something to entice the speakers, in addition to the $100 discount on registration offered by the conference?
- Need to submit list of speakers by November 1, 2012.
Deadline for computer demo- Nov 1st
I would imagine a SIA demo would be appropriate. - JP
Biocuration 2013 conference, Cambridge, 7-10th April 2013
submission deadline for papers and abstracts for posters is 30th November. Papers will be published by DATABASE.
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?
PRO Consortium members: Cathy Wu, Alan Ruttenberg (Buffalo)
