Analyse génétique et expression de gènes au cours de l'embryogenèse chez les plantes supérieures

This review describes and discusses recent attempts to analyze the embryogenesis process in higher plants, through combination of descriptive, experimental, and genetic approach. Analysis of gene expression profiles has permitted to build hypothesis concerning the induced mechanisms in early phases of embryogenesis in higher plants. Such mechanisms involve specific transcriptional and post-transcriptional regulatory pathways as well as diverse signal transduction processes at each stage of plant development.
