Indirect Somatic Embryogenesis

Having produced the embryos of cactusCopiapoa tenuissimaRitt. formamonstruosaat the globular stage and callus, we investigated the effect of abscisic acid (ABA) in the following concentrations: 0, 0.1, 1, 10, and 100 μM on successive stages of direct (DSE) and indirect somatic embryogenesis (ISE). In the indirect somatic embryogenesis process we also investigated a combined effect of ABA (0, 0.1, 1 μM) and sucrose (1, 3, 5%). The results showed that a low concentration of ABA (0-1 μM) stimulates the elongation of embryos at the globular stage and the number of correct embryos in direct somatic embryogenesis, while a high ABA concentration (10–100 μM) results in growth inhibition and turgor pressure loss of somatic embryos. The indirect somatic embryogenesis study in this cactus suggests that lower ABA concentrations enhance the increase in calli fresh weight, while a high concentration of 10 μM ABA or more changes calli color and decreases its proliferation rate. However, in the case of indirect somatic embryogenesis, ABA had no effect on the number of somatic embryos and their maturation. Nevertheless, we found a positive effect of sucrose concentration for both the number of somatic embryos and the increase in calli fresh weight.

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.
