      Introduction. Somatic embryogenesis (SE) provides a model system for the investigation of cellular totipotency and for the observation of early differentiation events during plant embryo development (Zimmerman ; Kurczyńska et al. ).In contrast to zygotic embryogenesis, somatic embryogenesis can easily be observed; the external conditions of embryo development can .   Oplopanax elatus is a medicinal plant on the verge of extinction because of overexploitation. In the present study, the effects of various factors on enhancing somatic embryogenesis and plantlet conversion were studied. Mature seeds were collected from a total of 13 plants from 4 mountains in South Korea, and the genetic distances were calculated to analyze the effect of genotype on somatic.

      A scanning electron microscopy (SEM) study during the induction of somatic embryogenesis from cell suspension cultures of Phoenix dactylifera L. performed by El-ghayaty et al.

The presence of lipid bodies in cultured tissues and somatic embryos of Daucu.s carotu L. has been reported [18]. However, there is no report regarding the ultrastructural changes in connection with storage lipid accumulation during zygotic embryogenesis in by:   In particular, none of the proteins specific of zygotic embryos required for maturation, previously identified, were accumulated in somatic embryos, namely the daucin (a globulin-type storage protein), the RAB25 protein (a late embryogenesis abundant protein) (Dodeman et al.

Somatic embryogenesis (SE) was described by Williams and Maheswaran () as ‘the process by which haploid or diploid somatic cells develop into differentiated plants through characteristic embryological stages without fusion of gametes’.

SE is a common process in nature (Raghavan, ; Tisserat et al., ; Vasil and Vasil, ), taking place during both embryonic and. Based on these observations, it was proposed that the same signal transduction pathway is activated during the acquisition of embryogenic competence by somatic cells and during zygotic embryogenesis after fertilization (Schmidt et al., ).

LRR-type cell surface RLKs possess a number of characteristic domains. The Arabidopsis thaliana LEC1 gene regulates embryo morphology and seed maturation. For a better understanding of its function, we isolated a carrot (Daucus carota L.

US-Harumakigosun) counterpart of this gene, C-LEC1, from a cDNA library of carrot somatic embryos, since carrot is a better model plant for preparing large quantities of somatic embryos at the same developmental stage.

Dc3 is a carrot lea class gene that is abundantly expressed during somatic and zygotic embryogenesis. Its expression is normally embryo‐specific and also can be induced by abscisic acid. The regulatory elements mediating the embryo‐specific expression of Dc3 reside within the proximal promoter region (− to +26), which is also essential for ABA‐induced expression.

Somatic embryogenesis (SE) is a means by which plants can regenerate bipolar structures from a somatic cell. During the process of cell differentiation, the explant responds to endogenous stimuli, which trigger the induction of a signaling response and, consequently, modify the gene program of the cell.

SE is probably the most studied plant regeneration model, but to date it is the least. Somatic embryogenesis has served as a model to understand the physiological and biochemical events that occur during plant developmental processes as well as a component to biotechnological advancement.

The first documentation of somatic embryogenesis was by Steward et al. in and Reinert in with carrot cell suspension cultures.

This short review emphasizes the importance of secreted molecules (peptides, proteins, arabinogalactan proteins, PR proteins, oligosaccharides) produced by cells and multicellular structures in culture media.

Several of these molecules have also been identified in planta within the micro-environment in which the embryo and endosperm develop. Questions are raised about the parallel between in. Lipid substances were present as a continuous layer in zygotic and somatic embryos cultured on solid medium.
