β¦ Synopsis
The form of higher plants is largely dependent upon cell division and expansion patterns. Taking a genetic approach, Takahashi et a/.(') have identified a regulatory molecule in Arabidopsis thaliana called DlMlNUTO (DIM), which is involved in determining the degree and direction of plant cell expansion. Their extensive characterization of a dim mutant suggested a direct involvement of the DlM gene in regulating cell elongation, perhaps by modulating the expression of structural genes which determine the orientation and elasticity of the cell wall.
