1 · What the graph read from it

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.

2 · The registry

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

Virus-induced gene silencing (VIGS) has great potential as a reverse-genetics tool in plant genomics. In this study, we examined the potential of VIGS in soybean seeds and the emergence stage of soybean plants using Apple latent spherical virus (ALSV) vectors. Inoculation of an ALSV vector (soyPDS-ALSV) carrying a fragment of the soybean phytoene desaturase (soyPDS) gene into soybean seedlings resulted in a highly uniform photo-bleached phenotype, typical of PDS inhibition, on the upper leaves throughout plant growth. The photo-bleached phenotype was also found on all immature pods, all seed coats, and about 50% embryos of seeds on soybean plants infected with soyPDS-ALSV. Infection with an ALSV vector (soyIFS2-ALSV) having a fragment of soybean isoflavone synthase 2 (soyIFS2) gene also led to a reduction of the levels of both soyIFS2- and soyIFS1- mRNAs and an isoflavone content in the cotyledons of about 36% mature seeds of infected soybean plants. Furthermore, VIGS of soyPDS was induced in the next generation plants by the seed transmission of soyPDS-ALSV. Thus ALSV vectors will be useful for studying gene functions in the reproductive stages and early growth stages, such as emergence and cotyledon stages, in addition to the vegetative stages of soybean plants.
