Trichome morphology terms #228

Open planteome-user opened 11 years ago

planteome-user commented 11 years ago

These are all of the botanical terms I could find for describing how trichomes grow. I need a trait term for "appressed" because we have a genetic gene that influences trichome formation so that the individual "hairs" grow at a more acute angle to the leaf surface than normal. I would imagine that all of the terms below will be needed at sometime by someone.

My suggestion would be to make a term "trichome growth habit" with the definition of "the physical appearance of the individual trichomes". Note that "glaborous" is the absence of trichomes.

acicular: needle-shaped appressed: lying closely and flatly against the plant's surface arachnoid: cobwebby canescent: gray-hairy and hoary capillary: very slender or hairlike cespitose: matted or growing in little dense clumps ciliate: fringed with hairs on the margin clavate: club-shaped (big at one end) downy: with very short, weak, soft hairs echinate: with stout, blunt prickles ensiform: sword-shaped glabrous: without hairs hirsute: with rough hairs hirtellous: like hirsute but with smaller or more diffuse hairs hispid: with stiff, bristly hairs hispidulous: like hispid but with smaller or more diffuse hairs hoary: closely covered with a white or whitish hairiness indumentum: a heavy covering or hairiness lanuginose: woolly or cottony lanulose: wooly with very short hairs mucro: a short and abruptly sharp or spiny tip mucronate: ending with a mucro pilose: shaggy with soft hairs plumose: feathery, like the pappus hairs of some composites puberulent: like pubescent but with smaller hairs pubescent: downy with short, soft hairs recurved: bent or curved downward or backward retrorse: bent or turned backward or downward septate: divided into partitions sericeous: silky setose: covered with bristles stellate: once or twice forked, or arms radiating from base tomentose: densely wooly or soft-matted hairiness tomentulose: like tomentose but less so torulose: twisted or knobby uncinate: hooked at the tip velutinous: velvety with erect, straight, moderately firm hairs villous: shaggy with long, soft, not matted hairs

OK, I see that we are using PATO for these "quality" terms so I should ask PATO to include them. So that means that we may have to change "leaf pubescence (TO:0002722)" to something else like "trichome growth habit (TO:0002722)" ? Since "pubescence" is a type of trichome growth habit. "trichome growth habit" could be a child of a new term "trichome anatomy and development trait" which is a child of anatomy and morphology trait (TO:0000017)

Agreed, we will create a 'trichome anatomy and development trait' term and then can we can look at populating it.

Laurel:

I found some of these terms in PATO. So what does that mean? Should these terms be "quality" values for some general growth and development term like "trichome growth habit"? So it would be something like TO:trichome growth habit PATO:clavate OR PO:trichome growth habit PATO:ensiform?

Or is the point of the TO that we have pre-composed terms? Also, remember that there are at least 2 kinds of trichomes, the glandular ones and the un-glandular ones. I don't know right here right now if both types get "appressed". On Jun 17, 2013, at 11:14 AM, Laurel Cooper wrote:

Created new term trichome anatomy and morphology trait (TO:0000911): A plant structure anatomy and morphology trait (TO:0000839) which is associated with a trichome (PO:0000282).

Added new child of trichome anatomy and morphology trait: trichome appressed (TO:0000912):A trichome anatomy and morphology trait (TO:0000911) which is associated with a trichome (PO:0000282) lying close to and flat against the plant's surface.

We have been working through these terms on the spreadsheet below: https://docs.google.com/spreadsheet/ccc?key=0Ar1O1Y7eIKhsdFN1MEZyalE5REVHZUJCVnVEdFVNZ0E#gid=0

Some of these terms seem to be describing how the trichomes are arranged on the leaf surface so we will continue working on these on the spreadsheet.

Revised name and def'n: trichome anatomy and morphology trait (TO:0000911) Was: trichome anatomy and morphology trait (TO:0000911), A plant structure anatomy and morphology trait (TO:0000839) which is associated with a trichome (PO:0000282). New: trichome morphology trait (TO:0000911), A plant structure morphology trait (TO:0000839) which is a quality of a trichome (PO:0000282).
