DESCRIPTION:Morphogenesis is a cellular process\, driven by interplay betw
 een gene expression and a growing network of cell interactions. Cells with
 in a plant meristem form a complex non-linear system\, and clearly possess
  self-organising properties. To date\, molecular genetic tools have provid
 ed the greatest insight into the network of interactions that underlie pla
 nt morphogenesis\, and these have allowed the identification of key genes 
 and pathways. However\, these analyses do not provide an explicit descript
 ion of the many parallel molecular\, cellular and physical interactions be
 tween cells that characterise morphogenesis. We have developed a battery o
 f microscopic and genetic tools to allow clear visualization of individual
  cells inside living tissues and have the means to manipulate them. This a
 llows the use of computer segmentation methods for the numerical descripti
 on of cell arrangements in plant tissue\, and the creation of morphogeneti
 c models for plant growth and morphogenesis. These systems provide an idea
 l platform for engineering of plant morphogenesis.
