Patterning of the Maize Embryo and the Perspective of Evolutionary Developmental Biology

  • Judith Nardmann
  • Wolfgang Werr


Genetic and molecular analyses in the dicot model plant Arabidopsis thaliana have identified numerous genes and different regulatory networks involved in embryonic patterning. Many genes encode members of transcription factor families. Orthologous genes can be identified by phylogenetic reconstructions based on conserved protein domains and functionally substantiated by gene expression patterns and mutant analyses. However, interspecies comparisons are necessary to validate networks identified in model species on the evolutionary scale. Comparative analyses between maize and Arabidopsis reveal both a significant conservation of gene expression patterns and thus presumably function as well as the evolutionary freedom for adaptation in the course of plant speciation.
