Somatic embryogenesis (SE) is a prominent mode of regeneration in plants. The acquisition of SE is predominantly invoked by the oxidative stress which plays an important role in signal transduction and cellular redox. Since balanced generation of oxidants is important to cellular differentiation, modulation in cell redox could be responsive to genotypic refinement for SE.

Signaling Overview of Plant Somatic Embryogenesis

 · 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 …

INTRODUCTION

exogenous Ca2+ in somatic embryogenesis provides evidence for calcium-mediated signaling. Possible role of polar auxin transport in somatic embryogenesis has also been demonstrated by the use of auxin transport blockers, leading to inability of somatic embryos to undergo morphogenetic transition to subsequent stages [11].
