The 3'-proximal part of the Plum pox virus P1 gene determinates the symptom expression in two herbaceous host plants.

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
Three major strains of the Plum pox virus (PPV) are the most important in Europe: PPV-D, PPV-M, and PPV-Rec. By combining the genomes of two different strains of PPV (PPV-D with PPV-Rec; PPV-D with PPV-M), 20 inter-strain chimeric infectious clones (CICPPV) were constructed. Biological properties of CICPPV were tested by inoculating them on different herbaceous host species susceptible to PPV. Four of the seven species tested, exhibited visible symptoms. In Nicotiana benthamiana all CICPPV induced systemic mosaic and leaf malformation. Pisum sativum showed a broad range of symptom severity (systemic chlorotic and necrotic lesions) but neither qualitative nor quantitative aspects of symptomatology were related to a single PPV genome locus. Nicotiana occidentalis and Nicandra physaloides proved to be suitable for symptom-based differentiation. Depending on the virus strain/chimera, N. occidentalis showed two types of symptoms: mild systemic chlorotic spots or local necrotic lesions/systemic vein necroses. N. physaloides reacted to the PPV infection either symptomless or by local necrotic lesions. Our results demonstrated that the P1/HC-pro region of the PPV genome appears to be the determinant of the symptom manifestation in these host plants. In silico analysis mapped it to the 3'-proximal part of the P1 gene.
