An infectious RNA with a hepta-adenosine stretch responsible for programmed -1 ribosomal frameshift derived from a full-length cDNA clone of Hibiscus latent Singapore virus.

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
Hibiscus latent Singapore virus (HLSV) is a member of Tobamovirus and its full-length cDNA clones were constructed. The in vitro transcripts from two HLSV full-length cDNA clones, which contain a hepta-adenosine stretch (pHLSV-7A) and an octo-adenosine stretch (pHLSV-8A), are both infectious. The replication level of HLSV-7A in Nicotiana benthamiana protoplasts was 5-fold lower, as compared to that of HLSV-8A. The replicase proteins of HLSV-7A were produced through programmed -1 ribosomal frameshift (-1 PRF) and the 7A stretch was a slippery sequence for -1 PRF. Mutations to the downstream pseudoknot of 7A stretch showed that the pseudoknot was not required for the frameshift in vitro. The stretch was found to be extended to 8A after subsequent replication cycles in vivo. It is envisaged that HLSV employs the monotonous runs of A and -1 PRF to convert its 7A to 8A to reach higher replication for its survival in plants.
