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)

postponed to future meeting

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.

whole plant fruit ripening stage (PO:0007010)

postponed to future meeting

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.
