- Comment
- A dormancy process (GO:0022611) is a developmental process in which dormancy (sometimes called a dormant state) is induced, maintained or broken. Dormancy is a suspension of most physiological activity and growth that can be reactivated. This term only applies to a whole plant (PO:0000003) in the gametophyte stage, not to the dormant stage of other plant structures. The dormant stage may be a response to environmental conditions such as seasonality or extreme heat, drought, or cold. Examples of a gametophyte dormant stage are the moss Polytrichum commune after it has undergone dessication (a type of resurrection plant), the boreal moss Polytrichum alpestre, whose shoot systems have annual growth segments due to a period of dormancy during the winter, the female gametophyte of Ginkgo biloba, which is dormant before fertilization, and dormancy of plant spores.
