Search for: [Abstract = "The ability of plant cells to regenerate complete organisms by somatic embryogenesis in vitro is one of the most important features of plants.Somatic embryogenesis may be defined as the development of embryos from somatic cells, haploid cells or gametopytes and has been observed in about 200 Angiosperm and Gymnosperm species. Somatic embryogenesis in vitro has been described as occuring in two general ways\: direct and indirect. The process of indirect embryogenesis can be divided into two phases\: 1\) induction of callus mass growth and 2\) development of proembryogenic cells into the embryos.The potential for somatic embryogenesis is not only genotype\-specific but also strongly dependent on the developmental stage of explant and culture conditions. Embryogenic cells formation requires auxin of which 2,4\-di\-chloro acetic acid \(2,4\-D\) is more commonly used, but the formation of somatic embryos occurs in auxin\-free medium. Although a wide range of basal \(media\) has been used for induction of somatic embryogenesis, the best results were obtained with the Murashige and Skoog salts.An understanding of somatic embryogenesis process increases our ability to utilize it as the technology for mass propagation, modification and improvement of plants."]
