Whole mount in situ localization of miRNAs and target mRNA transcripts in plants

Thefunctional characterization of miRNAs ofteninvolves understandingof their spatiotemporal expression, which mostly relies on reporter-based or in situ hybridization studies. The available in situlocalization methods follow separate protocols for pre-hybridization, hybridization, post-hybridization, and detection steps for both miRNA and mRNA transcripts in plants. In this study, we present a single method which can be used for whole mount in situ localization of both miRNAs and mRNAs in different plant tissues. Our modified method providesenhanced sensitivity for the localization of miRNA and their target transcripts. Consequently, a less laborious, time-saving, economic and efficient method has been proposed by the modification of pre-hybridization, hybridization, post-hybridization and detection steps.
