Abstract	This paper for the first time provides insights into the important roles of the miRNAs during blooming period in Populus simonii × P. nigra. MicroRNAs (miRNAs) are small RNAs that act as regulators of eukaryotic gene expression at the post-transcriptional level. Using high-throughput sequencing technology, we analyzed miRNAs in Populus. simonii × P. nigra at three stages of male flower bud development (pollen at the tetrad, uninucleate, and binucleate stages, respectively), using shoot tips and vegetative buds as controls. In total, 305 differentially expressed miRNAs from 49 families were identified. Among the 49 families, 17 were highly or moderately conserved in other species. A higher number of differentially expressed miRNAs were down-regulated in male flower buds compared with vegetative organs. Quantitative real-time PCR showed that almost all miRNAs have the same expression pattern as in the cluster results. Gene ontology enrichment analysis provided an indication of the possible functions of the miRNAs in male flower bud development.
