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

Background: Until recently, the mechanism underlying methyl jasmonate (MeJA)-mediated suppression of ethylene metabolism and its impact on quality formation in ripening tomatoes has not been fully clarified. This study aimed to investigate how exogenous MeJA application at the breaker stage affects endogenous jasmonates (JAs), ethylene production, metabolic pathways, and flavor profiles in 'FL 47' tomatoes. Methods: Exogenous MeJA was applied to red 'FL 47' tomatoes at the breaker stage. We measured endogenous JAs (especially JA-Ile), ethylene production, enzyme activities (LOX, AOC, AOS, OPR, ACO, ACS), mRNA abundances of related genes ( Results: MeJA treatment suppressed endogenous JAs (JA-Ile by 13%) and ethylene production by 33%. Enzyme activities in metabolic pathways were reduced to over 87% of control levels, and mRNA abundances of the aforementioned genes decreased by 17-30%. Production of sugars, organic acids, and volatiles was altered, leading to changes in flavor profile. Specifically, six key ethylene-regulated volatiles (geranyl acetone, 1-penten-3-one, 6-methyl-5-hepten-2-one, 2-methyl butanal, 3-methyl butanal, 3-methyl butanol) were reduced, concomitant with 19-29% lower mRNA abundances of biosynthetic genes ( Discussion: By considering the positive relationship between endogenous JA-Ile and ethylene levels in ripening fruit, our results imply that MeJA-mediated changes in aroma profile in red 'FL 47' tomatoes may result from mitigated endogenous JAs (especially JA-Ile) and ethylene biosynthesis and signaling transduction processes. These findings enhance understanding of hormone interactions in fruit quality formation and suggest potential applications for improving post-harvest tomato flavor.
