Somatic Embryogenesis: Fundamental Aspects and Applications

Abstract

Somatic embryogenesis (SE), the process through which already differentiated cells reverse their developmental programme and become embryogenic, requires drastic changes in the transcriptome of the explant cells. Among the various factors that underlie this developmental switch, genes encoding transcription factors (TFs), which constitute the sequence-specific DNA-binding proteins, are widely accepted as playing a central function in the gene expression regulation. In recent years, intensive analysis of the global transcriptomes of plant cells that are undergoing embryogenic transition and the use of Arabidopsis (a model in plant genomics) in studies on the genetic control of SE have substantially contributed to the identification of SE regulators. A survey of SE-associated transcriptomes illustrated the combinational effects of stress and hormone signalling that are related to the in vitro environment that is imposed during a culture. Accordingly, among the TFs that are considered to be essential in SE induction, those that are involved in stress and hormone plant responses and especially flower development were found to be most frequent. This chapter provides a comprehensive review of the current knowledge about the TFs that are involved in the induction of SE in plant explants that are cultured in vitro. In addition to a general characterisation of the TF transcriptomes that are associated with SE induction in different plants, the individual TF genes with documented functions in the regulation of SE are presented with a special reference to their possible targets and the TF-controlled molecular mechanisms that underlie SE induction.
