The miRBase:Targets database predict targets in the UTRs of 37 different animal genomes from Ensembl [5,7]. Here, we describe recent developments of the miRBase database to address this issue. NCBI Gene Summary for MIR186 Gene. "The miRBase database is a searchable database of published miRNA sequences and annotation. At the time of this study, only 119 wheat miRNAs were registered in miRBase (release 21), while the number of registered Brachypodium, rice, and maize miRNAs was 525, 713, and 321, respectively. Potential miRNA star sequences were identified from the sRNA data set to provide additional evidence.
