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

Jasmonates influence carotenoids biosynthesis, the pigments responsible for tomato fruit coloration, but their effect on carotenoids synthesis remains controversial. Lycopene is the predominant carotenoid in ripe tomato fruits, accounting for more than 90% of the total carotenoid content in the fruit. Our study clarified this paradox by demonstrating that methyl jasmonate (MeJA) affects post-harvest tomato lycopene accumulation differently depending on light conditions and we identified SlPIF1a as the central regulatory factor mediating this light-JA crosstalk. In light, MeJA enhances lycopene synthesis by directly activating the expression of the SlPSY1 gene through the SlMYC2 transcription factor. SlMYC2 also inhibits the expression of SlPIF1a, encoding a negative regulator of light signal that degrades in light and accumulates in darkness. In dark conditions, the accumulated SlPIF1a interacts with SlMYC2 inhibiting its activation on SlPSY1 expression. Additionally, the MeJA-induced acetyltransferase SlNATA1 interacts with and acetylates SlPIF1a, enhancing its repression on SlPSY1. Our research uncovers a new mechanism for the dual regulation of lycopene synthesis by jasmonic acid under different light conditions.
