ok, let's add some comments Going back to the Levesque et al (2006) paper. I am still not sure how they were able to discern asymmetric cell divisions (fig 2J). I just feel the authors are overextrapolating, or state it as "matter of fact." I agree that SHR has a role in cell division....

C'mon everyone, post! Let's have a comment frenzy! The blog is kind of boring if we don't actually use it.
I mean, I know I'm mostly just putting off studying for my biochem exam, but....
Questions 9/21/06 Cat 1) Pertaining to Surge and Destroy: Does the lack of lethal mutants with single mutations in the PIN proteins suggest that a certain amount of Auxin can be transported without PINs or that there is a compensation during embryogenesis?
2)...

Mark's Questions 1) are there seperate sets of ARFs, AUX/IAA proteins, etc. for IAA and IBA etc? Do the same PIN proteins interact with IAA and IBA? The generalization of "auxin" is confusing...
2) I'm not sure I understand how (theoretically) the presence of ARFs...
Jenik 1.-How good or how reliable are results that came from DR5 experiments? By the way described it seems there's too much uncertainty in using DR5 as a reporter of IAA activity.
2.- Why would nph4 and nph4-like mutants exhibit deficiency of cell expansion only...

9/14/06 questions, Wildwater et al. Questions for Wildwater:
1) What exactly are "lox" recombination sites?
2) Their interpretation was that SCR has opposing effects in relation to RBR function and activity--what might this mechanism look like?
3) Where is the proximal meristem? ...
Wildwater-Qs In the scr-4, rBRr double mutant there's a restoration of the QC along with additional columella cells but there is no restoration of root size. I'm not sure how this is possible? I would guess that scr is also required for QC maintenance?
In page 1342 top...
Questions for RBR Paper Question 1) In the model on page 1345 the authors show a pathway for RBR pathway action and interaction in plants, however I feel that this model is a bit premature, is there any other evidence in plant systems to support this model?
Question 2) The...

Plant Development Posting is Set Okay, I guess I don't have an excuse for posting anymore! I am on the list now!
Cat
Lecture notes online now The link for the lecture notes is (and was) active. I hope everyone can now post new entries now; I have "invited" you and you should have received an email (unless I misspelled your email).
I did not get a chance to talk about auxin and the paradox that...

Questions frm stds for Levesque questions for sept 10th
1) On page 744, the authors discuss the target validation for 4 out of the eight candidates. They describe expression patterns for SCR, MGP, NUC, but their is no evidence for TRI, is there?
2) What type of mutations are shr-2 and...

Control of flowering map This post is in regard to Bob's comments about the many ways that flowering is controlled in Arabidopsis.
This is a late post because it took me a while to figure out how to add a jpg. If anyone is missing a toolbar above their text...
