Legume terms
submitted by Austin Mast
Several terms have already been dealt with (Taproot, Stem Hair, Prickles, Anther pore and anther slit)
Fascicle The term fascicle can refer to different structures in different taxa. Suggest we use the term Fabaceae fascicle in this case.
Suggested def: A reproductive shoot system that ...
(in the Papilionoideae) "Pseudoracemes (Fig. 5B) differ from racemes in that two to several flowers are initiated in each bract axil rather than just one as in a raceme. The cluster of flowers at each node is called a fascicle. The order of initiation among flowers at a node (Fig. 5B, Psoralea macrostachys DC) shows the fascicle to be a short shoot topped by a second order inflorescence apical meristem. This meristem initiates flowers in a bilaterally symmetrical order: a single abaxial flower, then two lateral flowers, another median abaxial, then two more laterals. The number of flowers per fascicle depends on the duration of the axillary inflorescence apex of the short shoot, which ceases activity after initiating the few flowers in the fascicle. No flowers are initiated adaxially (toward the first order axis) on the short shoot (Tucker, 1987b; Tucker and Stirton, 1991). The short shoot in a pseudoraceme can be distinguished from a cyme in that every flower is bract subtended in a pseudoraceme." Source: Tucker, 2003, Flora

tuber growth and development stages
This item has been open on SF since 6/2009
I have a bunch of potato genes which are expressed in different tuber developmental stages (e.g. the potato pmt gene is expressed in small sprouts only (http://www.ncbi.nlm.nih.gov/pubmed/16088399).
Suggested stages:
-sprout development (does this correspond to tube axillary bud development? Should come after tuber maturation)
-tuber initiation
-tuber growth
-tuber maturation
How we work these in will depend on restructuring of PGDSO

Adding/modifying the root terms
submitted by Rich Zobel (Nov 2009)
TraitNet requests
proposed def: A short, enlarged storage stem in which the internodes do not elongate. Comment: usually underground.
child of stem (PO:0009047).
Their comment: is synonym to Tubercle
podarium (from Beentje 2010): (in cacti or other succulents) a modified leaf base functioning as the photosynthesising organ.
tubercle (from Beentje 2010): (in ball- or barrel- shaped cacti), cone-shaped protuberances that are elnarge modified leaf bases fused with adjacent stem tissue (tubercle has two other definitions as well).
proposed def:
definition from Beentje (2010): erect (breathing) root protruding above the soil, encountered especially in mangroves
proposed def: A root that is erect and protrudes above the soil, found in trees that live in flooded habitats such as mangroves. Comment: Pneumatophores may provide oxygen to below ground roots growing in flooded soils.
We dealt with this under terms without is_a parents
definition from Beentje (2010): reproductive portion of a plant, such as a seed, fruit or fragment of fruit, that is dispersed and may give rise to a new plant.
We could add this term as a kind of upper level bin term (similar to trichome)
Should probably be a synonym of strobilus (PO:0025083). Narrow or exact?
rom Crum (2001): a cluster of fern sporangia from Beentje (2010): (of pteridophytes) structure bearing or containing groups of sporangia.
Proposed definition: A cardinal organ part composed of a cluster of two or more adjacent sporagia on the surface of a leaf. Comment: May be enclosed by an indusium.
Part_of vascular leaf, has_part sporangium
Defintion from Beentje (2010): a slender, coiling structure derived from a branch, leaf or inflorescence and used for climbing.
tendrils can derived from multiple types of structures. Suggest we make separate terms:
branch tendril (child of branch): A branch that is slender and coiling. Comment: Aids plant in climbing.
leaf tendril (child of leaf): A leaf that is slender and coiling and lacks a lamina. Comment: Aids plant in climbing.
leaflet tendril (child of leaflet): A leaflet that is slender and coiling. Comment: Aids plant in climbing.
leaf apex tendril (child of leaf apex): A leaf apex that is slender and coiling. Comment: Aids plant in climbing.
Can add other types of tendrils if they come up or users need them.
terms for seed development stages
This is a fairly new request for terms for cotton
