Web2 feb. 2024 · Plant miRNAs are encoded by families of MICRORNA ( MIR) genes. The roles of individual MIRs are relatively poorly understood because loss-of-function mutant alleles are not available for most of them, and functional redundancy is assumed to occur among the members of a single MIR family. WebmicroRNA172 (miR172) is conserved in plants and plays important roles in plant development. Plant species have multi-ple MIR172 genes that can produce conserved mature miR172 sequences in different tissues and at different developmental stages.1-3 The mature miR172 sequences target mRNA of a sub-family of APETALA2 (AP2) genes by …
