Posttranscriptional control of gene expression can be achieved through RNA interference when the activities of Dicer-like (DCL), argonaute (AGO) and RNA-dependent RNA polymerase (RDR) proteins are significant. In this study, we analysed the expression of seven AGO, five DCL and eight RDR genes in cucumber under cold, heat, hormone, salinity and dehydration treatments using quantitative reverse-transcription PCR (qRT-PCR). All CsAGO, CsDCL and CsRDR genes were differentially expressed under abiotic stress treatment. In response to abiotic stress treatment, most genes were expressed at higher levels in flowers or stems than in other organs, whereas some CsAGOs (CsAGO1c, CsAGO6 and CsAGO7) and CsRDRs (CsRDR1d andCsRDR2) were highly expressed in roots during dehydration treatment. The expression patterns indicate that most CsDCLs, CsAGOs and CsRDRs respond to abiotic stress, and stems or flowers are the most sensitive organs, followed by roots. This is the first report of expression analysis of all CsDCL, CsAGO and CsRDR family genes in cucumber under abiotic stress, whichprovides basic information and insights into the putative roles of these genes in abiotic stress. The results of this study should serve as a basis for further functional characterization of these gene families in cucumber and related Cucurbitaceae species.
