organism: Xenopus laevis
description: MicroRNAs (miRNAs) are known to play diverse roles in the regulation of vertebrate development. To investigate miRNA-target mRNA relationships in embryonic development, we have carried out small-RNA sequencing to identify miRNAs expressed in the early gastrula of Xenopus laevis. We identify a total of 180 miRNAs, and we have identified the locations of the miRNA precursor sequences in the X. laevis genome. Of these miRNAs, 141 represent miRs previously identified in Xenopus tropicalis. Alignment to human miRNAs led to the identification of 39 miRNAs that have not previously been described for Xenopus.
