摘要： Long-Non-Coding RNAs (LncRNAs) are a class of non-coding endogenous RNAs contributing to numerous biological processes. LeERF1 is a tomato ethylene response factor (ERF) near the end of the ethylene signal transduction pathway. To identify lncRNAs in tomato and elucidate their roles in ethylene signaling, deep sequencing was deployed in over-expression and repression LeERF1 transgenic and control tomato fruits. A total of 397 lncRNAs were identified, including 169 tomato lncRNAs that had not previously been identified. Among these, 12 were differentially expressed between the transgenic and control tomato fruits. Numerous lncRNA target genes were identified including many associated with ethylene signaling including auxin response factors and auxin-induced proteins, F-box proteins, ERFs and MADS-box proteins. In addition, two lncRNAs were found to be the precursor of three miRNAs and four lncRNAs could be targeted by five miRNAs. We propose a regulatory model highlighting the relationships between lncRNAs and their targets involved in ethylene signal transduction which establishes a foundation for addressing the role of LncRNAs in ethylene response.
