chromatin questions 1) What exactly do the authors mean when they say "underlying positional information" pg.494; if they are referring to position of chromatin, what is the "position" of chromatin?
2) Criticism:Why was the wer mutant FISH data in figure 1 not discussed? I can...

Questions 1) How does Ago1 interact with the siRNA pathway and how would they explain the changes in phenotype with the crosses?
2) Would overexpression of Ago1 affect the Cuc2 mRNA and change the meristem boundary per the discussion?
3) Did the supplimental...

AGO questions - CER 1) On page 512, the authors discuss the affects of the clf mutant on the ago1 phenotype. What do they mean when they say "clf does not rescue the loss of meristem function in ago1-10"? I didn't think a mutated gene,even if it is a repressor, could rescue...

? Boss 2006
1) In Figure 7, the Arabidopsis plants displayed filamentous
structures. Could these parts be petals, siliques, or some other part in its
very early development or just an outgrowth like extra cartilage on a mammal? ...

1) On the Mallory paper, I am still not sure how the transformation of
wild types were able to exhibit mutant phenotype. Should the wild type
copy be able to overcome the mutant phenotype?
The wild type would not be expected to overcome...
in response to Christina RE: Mallory 2005 Christina asked: Why did they not do a protein blot? (figure 5) just because there is no cleavage
does not mean that there is protein being produced. The miRNA might bind weakly
preventing translation to occur.
Good point at least in...
response to Ramon regarding Short root. I guess that the evidence for SHR causing the assymetric cell division is that it is missing in the mutant and they seem to be able to induce assymetric cell divisions in the pSHR:SHR:gr construct plants that are not seen in the controls.What genes would be...

Mallory, Vazquez 1) On the Mallory paper, I am still not sure how the transformation of wild types were able to exhibit mutant phenotype. Should the wild type copy be able to overcome the mutant phenotype?
2) On the Vazquez paper, why is silencing shown as seperate...

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...
