摘要： High-throughput small RNA sequencing and degradome analysis were used in this study to thoroughly investigate the role of miRNA-mediated regulatory network in tuberous root development of radish. Samples from the early seedling stage (RE) and the cortex splitting stage (RL) were used for the construction of six small RNA libraries and one degradome library. A total of 518 known and 976 novel miRNAs were identified, of which, 338 known and 18 novel miRNAs were expressed in all six libraries, respectively. A total of 52 known and 57 novel miRNAs were identified to be significantly differentially expressed between RE and RL, and 195 mRNAs were verified to be the targets of 194 miRNAs by degradome sequencing. According to the degradome analysis, 11 differentially expressed miRNAs had miRNA-mRNA targets, and 13 targets were identified for these 11 miRNAs. Of the 13 miRNA-mRNA targets, 4 genes (RSG11079.t1, RSG11844.t1, RSG16775.t1, and RSG42419.t1) were involved in hormone-mediated signaling pathway, 2 gens (RSG11079.t1 and RSG16775.t1) were related to postembryonic root development, and 1 gene (RSG23799.t1) was involved in anatomical structure morphogenesis, according to the GO function analysis for biological process. Target Genes participated in these processes are important candidates for further studies. This study provides valuable information for a better understanding of the molecular mechanisms involved in radish tuberous root formation and development.
