ath-miR166a-3p: Ath-mir166a-3p, a member of the miR166 family, was found to have similar relative transcript levels to other miRNAs in a sequencing study [PMC8472271]. The expression levels of the target gene XPB2 were authenticated for ath-mir166a-3p, along with other miRNAs [PMC8472271]. XPB2 was predicted to be targeted by multiple miRNAs from the miR166 family, including ath-mir166a-3p [PMC8472271]. The expected opposing expression relationships were observed between ath-mir166a-3p and its target gene XPB2 [PMC8472271]. Ath-mir166a-3p was found in extracellular vesicles isolated from broccoli flower heads, along with other miRNAs [PMC10053153]. It was also identified as a regulator of HD-ZIP transcription factors in broccoli and was targeted by multiple miRNAs, including ath-mir166a-3p [PMC10039531]. In a study on differentially expressed miRNAs and their target genes, ath-mir166a-3p was one of the screened miRNAs for RT-PCR verification [PMC9222952].
