Abstract
Small RNAs play important regulatory roles in gene expression during development, stress response and phytohormone signaling. Two major classes of sRNAs are found: microRNAs (miRNAs), and small interferent RNAs (siRNA). These molecules are usually 20–24 bases long, present high complementarity to their mRNAs targets and regulate the transcription or translation processes. In spite of the substantial amount of experimental work with plant small RNAs, little is known about their expression pattern and function during somatic embryogenesis, a process commonly used for genetic transformation, plant propagation and artificial seed production. In this chapter, an overview of the studies involving microRNAs in plant somatic embryogenesis is approached with a particular emphasis in maize embryogenic callus induction, subculture and regeneration.
