|a Thermosensitive cytoplasmic male sterile (TCMS) lines play an important role in wheat breeding, heterosis utilization, and germplasm innovation. MicroRNAs (miRNAs) can regulate the expression level of target genes by inhibiting the translation of these genes. YS3038 is a wheat TCMS line. In this study, the fertility conversion mechanism of YS3038 was studied by examining the abortion characteristics of YS3038, the regulation pattern of miRNAs and the target genes of miRNAs in YS3038. MiRNA-seq was performed on three important stages of YS3038 under sterile and fertile conditions. Then, the clean reads were aligned with some databases to filter other ncRNAs and repeats. The known miRNAs and novel miRNAs were predicted by sequence comparison with known miRNAs from miRbase. Differential expression of miRNAs between different stages and between different fertile conditions was analyzed, and functional analysis of target genes with opposite expression patterns as those of the miRNAs was conducted. The Ubisch bodies and microspores of sterile anthers were covered with filamentous materials. The degradation of the tapetum cells, the chloroplast structure of endothecium cells, and the microspore structure were abnormal. Microspore development was hindered from the late uninucleate stage to the binucleate stage. Twenty, 52, and 68 differentially expressed miRNAs (DEmiRs) were identified at the early uninucleate, late uninucleate, and binucleate stages, respectively, and there were 0, 7, and 72 differentially expressed target genes (DETGs), respectively, at these three stages. At the binucleate stage, 29 DEmiRs had 41 target mRNAs in total, and the expression patterns of the 41 target mRNAs were opposite to those of the 29 miRNAs. Fifteen significantly enriched KEGG pathways were associated with the 41 target mRNAs. Leucine-rich repeat receptor-like kinases (LRR-RLKs) play important roles in plant developmental and physiological processes. Some studies have shown that the expression of LRR-RLKs is related to the differentiation of microsporocytes and tapetum cells and to male sterility. An LRR-RLK (TaeRPK) gene was silenced by the barley stripe mosaic virus-induced gene silencing (BSMV-VIGS) method, and the seed setting rates of the TaeRPK-silenced plants (3.51%) were significantly lower than those of the negative control plants (88.78%) (P < 0.01). Thus, the TaeRPK gene is likely to be involved in the fertility conversion of YS3038
