DESCRIPTION:Organogenesis in plants is closely related to the activity of 
 the shoot apical meristem. The formation of lateral organs\, such as leave
 s or flowers\, is initiated at the meristem periphery by the establishment
  of local auxin maxima. In contrast to flowers\, leaves are organs of dors
 iventral symmetry\, which is manifested in adaxial-abaxial leaf polarity. 
 Adaxial and abaxial leaf sites are anatomically and functionally distinct\
 , and their juxtaposition is essential for generating the flattened shape 
 of a leaf blade. In this talk I will discuss how adaxial and abaxial cell 
 fates are established at the shoot apical meristem of Arabidopsis\, and wh
 at the role of auxin is in this process. Furthermore\, I will show that th
 at tracing cell lineages based on time-lapse imaging of a growing shoot ap
 ex is a useful toot that enables to link cell fates with dynamic gene expr
 ession patterns.
