Abstract

Somatic embryogenesis is the process by which somatic cells are induced into an embryogenic state, followed by differentiation into embryos. Somatic embryogenesis, in addition to being a method of propagation, can serve as an experimental tool for research into plant embryo development. This is a review of the current literature on in vitro plant somatic embryogenesis and the molecular advances made to identify genes expressed during the various stages of this process. Some factors hindering the elucidation of the molecular mechanisms underlying somatic embryogenesis are discussed.

L‘embryogenèse somatique est le processus par lequel les cellules somatiques passent à  l‘état embryogène et se différencient en embryons. En plus de constituer une méthode de propagation, elle peut servir d‘outil expérimental de recherche pour développer des embryons de plantes. Le présent document est une revue de la documentation sur l‘embryogenèse somatique végétale in vitro et sur les progrès réalisés à  l‘échelle moléculaire pour identifier les gènes exprimés au cours des divers stades du processus. On examine aussi certains facteurs qui rendent difficile l‘élucidation des mécanismes moléculaires de l‘embryogenèse somatique.
