Abstract
MicroRNAs (miRNAs) are small regulatory noncoding RNAs varying in length between 20 and 24 nucleotides. They play a key role during plant development by negatively regulating gene expression at the posttranscriptional level. Moreover, recent studies reported several miRNAs associated with abiotic stress responses. Small RNA cloning and high-throughput deep sequencing methods provide expression profiles of not only known miRNAs, but also novel miRNAs. In this chapter, we describe the methods used to identify and characterize abiotic stress-associated miRNAs and their target genes.
