New revision of Plant Ontology is in cvs

[Katica Ilic]

Hi All,

I've commited the new revision of Plant Ontology to cvs:
anatomy.ontology rev 1.31
ontology.definition rev 1.33
temporal.ontology rev 1.3

I added 12 new terms to Plant Structure Ontology (see the thread from Jan
27):
Term: cuticle
Term: casparian strip
Term: filiform apparatus
Term: root tip
Term: primary root tip
Term: lateral root tip
Term: pollen tube tip
Term: root hair tip
Term: septum
Term: lenticel
Term: tetrad of microspores
Term: valve

Changes incorporated on Jan 31 2005.

Term: cuticle
Def: A layer of fatty material, cutin, rather impervious to water, located
on the outer walls of epidermal cells.

Cell
  (i) epidermal cell
        (p) cuticle

Term: casparian strip
Def: A band-like wall formation within primary walls that contains suberin
and lignin; typical of endodermal cells in roots, in which it occurs in
radial and transverse anticlinal walls.
root
  (p) root cortex
     (p) root endodermis
         (p) casparian strip

Term: filiform apparatus
Def: A complex of cell wall invaginations in a synergid cell similar to
those in transfer cells.

Synergid cell
  (p) filiform apparatus

Term: root tip
Def:  Top portion of the root including meristem and root cap

Term: primary root tip
Def: The portion of the primary root including the meristem and root cap.

Term: lateral root tip
Def: The portion of the lateral root including the meristem and root cap.

root
  (p) root tip
  (i) lateral root
       (p) lateral root tip
   (i) primary root
        (p) primary root tip
  (i) lateral root tip
  (i) primary root tip

Term: pollen tube tip
Def: Tip portion of the pollen tube that is rapidly growing.

male gametophyte
 (p) pollen tube
    (p) pollen tube tip

Term: root hair tip
Def: Tip portion of an outgrowth of a root epidermal cell.

epidermis
(p) epidermal cell
  (i) root hair
     (p) root hair tip

Term: septum
Def: A thin partition or membrane that divides a cavity or a mass of
tissue, e.g., in anther, ovary or fruit.

carpel
  (p) septum

and

anther
(p) septum

and

fruit
(p) septum

Term: lenticel
Def: Loosely-packed mass of cork cells occurring especially in the young
stem, bark or even leaf of a plant, visible on the surface as a raised,
often powdery-appearing spot, through which gaseous exchange occurs.
stem
(p) lenticel

Term: tetrad of microspores
A group of four haploid cells that remained joined together shortly after
meiosis. Each cell will give rise to the male gametophyte.

androecium
 (p) stamen
     (p) anther
         (p) microsporangium
            (p) microsporocyte
               (d) tetrads of microspore
                    (d) microspore

In this case, we have 'tetrad of microspores' with only develops_from
relationship.

Term: valve
Def: valve: a portion of an organ that is fragmented; in capsule,
theportions into which the pericarp splits at maturity.

fruit
 (p) fruit abscission zone
 (p) pericarp
 (p) seed
 (p) valve
