    • All transcriptional reporters were made by polymerase chain reaction (PCR) fusion, from the predicted start to the next predicted upstream gene, and extrachromosomal arrays were marked with pha-1(+). Expression of mir-61 transcription was studied by using the arls 107 integrant, which displayed the same pattern as extrachromosomal arrays.

    • mir-61 is also expressed in cells of the somatic gonad in which LIN-12 is active, and this expression is also lost when the LBSs are mutated (Fig. 1, B and C). In contrast, expression in other tissues where we have no evidence that lin-12 activity is functionally relevant, such as intestinal cells, is unaffected. These observations suggest that the loss of expression in P5.p and P7.p reflects lack of response to lin-12 and not loss of a general enhancer.

    • We used two separate arrays because of possible promoter interference that we have experienced when using the same promoter to drive two different gene products in the same array. For the assessment of many targets, the assay could be improved by integrating the transgene expressing the miRNA.
