Abstract
Post-transcriptional gene regulation occurs by different mechanisms, one of them is the regulation by small RNAs (sRNAs), which are regulatory elements non-coding. In plants, among different classes of sRNAs, micro-RNAs (miRNAs) are the most studied in various development processes, including embryogenesis. However, in gymnosperms, the functions of specifics miRNAs in the regulation of ge…
