whole plant fruit formation stage

[planteome-user]

The existing term 5 fruit formation stage (PO:0007042) is defined as "Formation of the seed-bearing structure after flowering." There are two major problems with this definition: one, it describes a process, not a stage, and two, it refers to development of a fruit, rather than to the development of a whole plant.

After reviewing the history of the PO and discussing these terms at the POC meetings on 8-14-12 and 9-4-12, we agreed that this term was originally created to describe a whole plant development stage during which fruit is being formed. We agreed to change the name and definition accordingly.

New proposed name: whole plant fruit formation stage

New proposed def.: A sporophyte reproductive stage (PO:0007130) that begins with the initiation of the first fruit (PO:0009001) of a growing season and ends with the beginning 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 annual plant will only have one fruit formation stage in its life, while a perennial may have one fruit formation stage for each growing season. 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.

subset for angiosperms

As specified in the PO definition of fruit, initiation of the first fruit begins with fertilization (formation of zygote). This can be defined more clearly in fruit development stages, then we can refer to those stages in the definition of this stage.

We expect that this definition will change slightly as we work on the new and revised terms for fruit development stages.
