Abstract
Small RNAs have vital roles in numerous aspects of plant biology. Deciphering their precise contributions requires knowledge of a small RNA’s spatiotemporal pattern of accumulation. The in situ hybridization protocol described here takes advantage of locked nucleic acid (LNA) oligonucleotide probes to visualize small RNA expression at the cellular level with high sensitivity and specificity. The procedure is optimized for paraffin-embedded plant tissue sections, is applicable to a wide range of plants and tissues, and can be completed within 2–6 days.
