1
Q
what req
A
ab/ad boundary
2
Q
where on leaf is division
A
proximal
3
Q
role of angusfolia
A
control width of leaf
4
Q
rotudfolia
A
control height of leaf
5
Q
what two processes imp in serration
A
pin1 and cuc2
6
Q
role of pin 1 in serration
A
polar subcell localisation
forms convergence points at margin of leaf
create localised auxin activity maxima which are req for serration outgrowth
7
Q
what are leaves of mut pin1 and cuc2 like
A
no serration
8
Q
leaves of continuous cuc2 expression
A
no serration
9
Q
what are the two functions of discontinuous cuc2 expr
A
pin1 repolariation req cuc2
localised down reg of cuc2 by auxin stabilises position of pin1 convergence points and auxin maxima on margin
cuc2 dependent growth repressions mark position of indentations
