Résumé
Somatic or in vitro embryogenesis is a unique embryo producing process from vegetative cells observed in plants since 1958. Even over 60 years of research, the transition of somatic cells into embryonic fate is still not elucidated fully. Various networks and signaling elements have been noted to play important role in this "vegetative to reproductive" transition process. The networks include genotypes, explant types, the sugar/carbohydrate sources, cultural/environmental conditions like light quality and intensity, dissolved oxygen (DO) level, cell density, plant growth regulator (PGR) (auxin and cytokinin) signaling, PGR-gene interplay, stresses are important and cause new cellular reprogramming during embryonic acquisition. A wide array of genes, specific to zygotic embryogenesis, also express during somatic embryogenesis. A few embryogenesis-specific genes such as SOMATIC EMBRYOGENESIS LIKE RECEPTOR KINASE, LEAFY COTYLEDON, AGAMOUS-LIKE 15, and BABY BOOM are crucial and have been discussed. The chapter focuses the importance of these gene products, e.g., proteins, enzymes, and transcription factors in regulating embryogenesis. Many of these encoded proteins act as potential somatic embryogenesis markers. Besides, important elements such as genotype, herbaceous/woody plants' response in culture in inducing embryos have been discussed. All these elements are connected and form network in complex fashion thus difficult to unfold fully; some of the current progress and developments have been presented in this chapter.
