PDSO Revisions: Whole plant development stages

gametophyte/sporophyte dormant stage

GO terms

GO has terms for dormancy process and seed dormancy, but no term for whole organism dormancy.

dormancy process (GO:0022611): The process in which a dormant state is induced, maintained or broken. Dormancy is characterized by a suspension of physiological activity. (They also have a term for seed dormancy.)

proposed new definition for dormancy process: A developmental process in which a dormant state is induced, maintained or broken.

Comment: A dormant state is characterized by a suspension of most physiological activity, and in plants, a suspension of growth.

seed dormancy (GO:0010162): The process in which a dormant state is induced, maintained and broken in a seed. Dormancy is characterized by a suspension of physiological activity that can be reactivated.

proposed new definition for seed dormancy: A dormancy process that has as participant a seed.

comment: Seed dormancy is characterized by a suspension of physiological activity that can be reactivated. Often requires special conditions for reactivation such as specific temperature, scarification, or leeching of inhibitors.

organism dormancy (new term): A dormancy process that has as participant a whole organism.

Comment: A dormant state in an organism is characterized by a suspension of most physiological activity. In plants, organism dormancy is marked by a suspension of growth and generally involves the formation of dormant buds. These may be above ground (in woody plants), at ground level (in herbaceous plants), or underground (in plants with tubers, bulbs, corms, or perennating rhizomes). Organism dormancy in plants may be preceded by the senescence of other plant parts such as leaves in woody plants or most of the shoot system herbaceous perennials. The end of organism dormancy in vascular plants is marked by resumed growth of buds and/or growth of vascular cambium. Organism dormancy in plants is generally an evolved response to environmental conditions such as seasonality or extreme heat, drought, or cold, although environmental stimuli may not be necessary for the onset of dormancy.

PO terms

sporophyte dormant stage (PO:0007132): A sporophyte development stage during which a sporophyte participates in an organism dormancy process (GO:xxxx).

comment: This term only applies to a whole plant in the sporophyte stage, not to the dormant stage of a seed, bud, or other plant structure, although a sporophyte dormant stage involves the formation of dormant buds. These may be above ground (in woody plants), at ground level (in herbaceous plants), or underground (in plants with tubers, bulbs, corms, or perennating rhizomes). Dormancy may be preceded by the senescence of other plant parts such as leaves in woody plants or most of the shoot system herbaceous perennials. The end of dormancy is marked by resumed growth of buds and/or growth of vascular cambium. The dormant stage is generally an evolved response to environmental conditions such as seasonality or extreme heat, drought, or cold, even though environmental stimuli may not be necessary for the onset of dormancy.

gametophyte dormant stage (PO:0025342): A gametophyte development stage during which a gametophyte participates in a dormancy process (GO:0022611).

comment: This term only applies to a whole plant in the gametophyte stage, not to the dormant stage of other plant structures. The dormant stage is generally an evolved response to environmental conditions such as seasonality or extreme heat, drought, or cold, even though environmental stimuli may not be necessary for the onset of dormancy.

review of definitions for embryo stage and plant embryo

embryo stage

We already had a term PO:0007631, embryo development stages, is_a seed development stage. This term was renamed embryo stage and made is_a sporophyte vegetative stage.

proposed def.:

embryo stage (PO:0007631): A sporophyte vegetative stage that occurs during the interval between the first cell division and one of the following: germination in seed plants, formation of the first true leaf after the cotyledon(s) in pteridophytes, cessation of division of the apical cell and initiation of development of the sporangium in bryophytes, or the beginning of the formation of organs (roots, shoot axes, or leaves) in cultured plant embryos.

Comment: The embryo stage generally starts after the first division of a zygote, but in the case of adventitious embryos, somatic embryos, other embryos that arise through apogamy, and cultured haploid embryos, it begins after the division of a single cell that is not a zygote. The end of the embryo stage varies among taxa.

plant embryo

Now that we have a working term for embryo stage, we can define plant embryo in terms of the stage.

existing def. plant embryo (PO:0009009): A whole plant in the early part of a sporophytic phase after the first cell division.

proposed def. plant embryo (PO:0009009): A whole plant that participates in the embryo stage (PO:0025369).

comment (basically the same as existing comment): An embryo is generally formed after the first division of a zygote, but in the case of adventitious embryos, somatic embryos, other embryos that arise through apogamy, and cultured haploid embryos, it is formed after the division of a single cell that is not a zygote. The end of the embryo stage varies among taxa. In seed plants, the embryo stage ends with germination. In pteridophytes, the embryo stage ends with the formation of the first true leaf after the cotyledon(s). In bryophytes, the embryo stage ends when the apical cell stops dividing and the sporangium begins to develop. In cultured plant embryos, the embryo stage ends when organs (roots, shoot axes, or leaves) begin to form.

-change from participates_in sporophyte development stage to participates_in embryo stage

We had a discussion a few weeks ago whether is better to define stages in terms of structures in terms of stages. In general, it is better to define stages in terms of structures. This works well for terms like trichome development stage. However, in the case of embryo stage, the structure is really a whole plant that is undergoing certain processes, and the stage is a more fundamental term.

zygote stage

We already have a term "A zygotic stage" (PO:0001097), is_a embryo stage. This was renamed zygote stage and made is_a sporophyte development stage.

proposed def. zygote stage (PO:0001097):A sporophyte development stage that occurs during the interval between syngamy and the first cell division.

As with the embryo stage/embry, RW thinks it would be better to define the stage, then define a zygote as a whole plant that participates the zygote stage, rather than the other way around.

Call for Symposia, Colloquia and Workshops:

RW, DWS and MAG put together a proposal for a half day hands-on workshop. The goal will be to teach people (mostly botanists) how to access and use the PO, including how to send feedback, suggest new terms, etc.

Proposal was submitted, waiting for news.

PJ: suggest that we go there with a 'draft' version of the Plant Phenotype Ontology and show them how to use these in character matrixes.

exhibitor's booth

We should also consider hosting an outreach booth.

Not a bad deal for non-profits: $500 for A 10 x 10 Booth Space at Botany 2012, and 2 complimentary registrations for the conference. (plus all the extras!)

• 2 months of Rotating Banner Ads in the online American Journal of Botany

• A Rotating Banner Ad in one edition of the online Plant Science Bulletin
