Somatic Embryogenesis in Angiosperms

Sexual Propagation of the Tunisian Spinescent Opuntia ficus-indica (L.) Mill., Morphogenetic Deployment and Polymorphism

“…Two and on rare occasions three embryos were detected for many wild Opuntias seeds (Trujillo and Gonzalez-Espinosa, 1991). Tisserat et al (1979) reported apomixis in several Opuntias among them O. ficus-indica. According to Perez (1993), the presence of polyembryonic seeds in germination tests varied from 10.9 to 18.5% for O. streptacantha and its hybrids, 3.6 to 24.7% for O. robusta, 0 to 14.3% for O. cochinera, 0 to 6.7% for O. leucotricha and 0 to 50% for O. rastrera.…”

Somatic Embryogenesis for Potato (Solanum tuberosum L.) Improvement

“…Somatic embryogenesis (SE) is a tissue culture technology first reported by Waris (1957) in fineleaf waterdropwort ( Oenanthe aquatica) and Reinert (1958) and Steward (1958) in carrot ( Daucus carota) and has now been described in at least 200 Gymnosperm and Angiosperm species (Tisserat et al 1979;Evans et al 1981;Tulecke 1987). It describes a developmental process involving one or more somatic cells that results in a morphological structure, similar to a zygotic embryo derived from a fertilized egg, capable of developing into a complete plant (Neumann et al 2009).…”

Antropología Etnobotánica Etnomedicina

“…La técnica de embriogénesis somática se basa en la formación de un embrión a partir de una célula somática, es decir, sin la necesidad de la fusión de gametos (Tisserat et al, 1979), lo que facilita la producción masiva de plantas in vitro. La obtención de embriones somáticos permite automatizar el proceso productivo, en cortos periodos de tiempo y en un espacio reducido.…”
