Overexpression of PSK-γ in Arabidopsis promotes growth without influencing pattern-triggered immunity.
Article in Plant signaling & behavior, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Phytosulfokine-α (PSK-α) is a disulfated pentapeptide with the sequence YIYTQ. As a new peptide hormone, PSK-α promotes plant growth and development but represses pattern-triggered immunity (PTI) against bacterial pathogens. Our recent study identified a novel phytosulfokine, PSK-γ, from soybean. The sequence of PSK-γ is YVYTQ in which the tyrosines are sulfated. Expression of PSK-γ significantly increased seed size and weight in transgenic plants by inducing embryo cell expansion. In this study, we further found that the constitutive expression of PSK-γ in Arabidopsis promotes the growth of vegetative organs as well as seeds. Moreover, overexpressed PSK-γ does not influence plant PTI against bacterial pathogens. These findings demonstrate a potential use of PSK-γ in genetic improvement of crop growth and yield by molecular breeding.
