Differential expression of the TMV resistance gene N prevents a hypersensitive response in seeds and during germination.

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
The dominant tobacco mosaic virus (TMV) resistance gene N confers a hypersensitive response (HR) at the site of TMV infection and protects tobacco against systemic spread of the virus. To study N gene activity in seeds and early seedling development, the avirulence gene of N, the helicase domain (p50) of the TMV replicase, was constitutively expressed in a tobacco genotype without N (nn). Transgenic F1 expressing N and p50 were generated by crossing with an NN genotype. Surprisingly, Nn F1 seeds expressing p50 are viable and germinate. Only about 5 days after sowing, seedlings started to show an HR. This paralleled the upregulation of several pathogenesis-related and HR genes. The timing of the HR is consistent with the upregulation of N gene transcript 4-6 days after sowing. The expression of p50 has a stimulating effect on the N gene transcript level during germination. These results show that tobacco seeds and very young seedlings do not express a functional N gene product.
