Definition
A sporophyte development stage (PO:0028002) during which a sporophyte participates in multicellular organism senescence. Source: POC:curators, GO:0010259
Comment
The sporophyte senescent stage is often preceded by the sporophyte reproductive stage, and it ends with death of the sporophyte, either as a result of senescence or some other cause. The sporophyte senescent stage may succeed the sporophyte reproductive stage in monocarpic plants that die after reproducing, such as annuals. This stage is distinct from sporophyte dormant stage, in which organs may senesce, but some parts of the plant remain alive. Multicellular organism senescence/aging (GO:0010259) includes loss of functions such as resistance to disease, homeostasis, and fertility, as well processes like cellular senescence, organ senescence, and wear and tear. The POC curators have requested to the GOC that they revise the definition of GO:0010259, to make it more appropriate for plants.
