Abstract
Plants possess a unique property called cellular totipotency which is a series of complex molecular and biochemical steps to produce a complete normal plant. Somatic embryogenesis, the most reliable and useful tool for in vitro plant propagation, uses this property of totipotency to regenerate a whole plant from competent somatic cells in the presence of endogenous or exogenous signals. Development of embryo from somatic cells is regulated by the differential expression pattern of a myriad of genes among which the most important regulator is somatic embryogenesis receptor kinase (SERK) gene. Phytohormones like brassinosteroids (BRs) play important roles in directing the plant cells to undergo restructuring program for differentiation, development, and organogenesis. Along with this, BR has been known to elicit a stress response mechanism in plants. SERK, a known LRR-RLK member, can form heterodimer complex with the main BR receptor, brassinosteroid insensitive 1 (BRI1), to induce BR-dependent signaling pathway. The present review encompasses the role of SERK in inducing somatic embryogenesis and its interaction with BR during BR signaling. © Springer India 2016.
