Trans-species microRNA loci in the parasitic plant Cuscuta campestris have a U6-like snRNA promoter.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Small regulatory RNAs can move between organisms and regulate gene expression in the recipient. Whether the trans-species small RNAs being exported are distinguished from the normal endogenous small RNAs of the source organism is not known. The parasitic plant Cuscuta campestris (dodder) produces many microRNAs that specifically accumulate at the host-parasite interface, several of which have trans-species activity. We found that induction of C. campestris interface-induced microRNAs is similar regardless of host species and occurs in C. campestris haustoria produced in the absence of any host. The loci-encoding C. campestris interface-induced microRNAs are distinguished by a common cis-regulatory element. This element is identical to a conserved upstream sequence element (USE) used by plant small nuclear RNA loci. The properties of the interface-induced microRNA primary transcripts strongly suggest that they are produced via U6-like transcription by RNA polymerase III. The USE promotes accumulation of interface-induced miRNAs (IIMs) in a heterologous system. This promoter element distinguishes C. campestris IIM loci from other plant small RNAs. Our data suggest that C. campestris IIMs are produced in a manner distinct from canonical miRNAs. All confirmed C. campestris microRNAs with documented trans-species activity are interface-induced and possess these features. We speculate that RNA polymerase III transcription of IIMs may allow these miRNAs to be exported to hosts.
