Precocious leaf senescence by functional loss of PROTEIN S-ACYL TRANSFERASE14 involves the NPR1-dependent salicylic acid signaling.

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
We report here that Arabidopsis PROTEIN S-ACYL TRANSFERASE14 (PAT14), through its palmitate transferase activity, acts at the vacuolar trafficking route to repress salicylic acid (SA) signaling, thus mediating age-dependent but not carbon starvation-induced leaf senescence. Functional loss of PAT14 resulted in precocious leaf senescence and its transcriptomic analysis revealed that senescence was dependent on salicylic acid. Overexpressing PAT14 suppressed the expression of SA responsive genes. Introducing the SA deficient mutants, npr1-5 and NahG, but not other hormonal mutants, completely suppressed the precocious leaf senescence of PAT14 loss-of-function, further supporting the epistatic relation between PAT14 and the SA pathway. By confocal fluorescence microscopy, we showed that PAT14 is localized at the Golgi, the trans-Golg network/early endosome, and prevacuolar compartments, indicating its roles through vacuolar trafficking. By reporter analysis and real time PCRs, we showed that the expression PAT14, unlike most of the senescence associated genes, is not developmentally regulated, suggesting post-transcriptional regulatory mechanisms on its functionality. We further showed that the maize and wheat homologs of PAT14 fully rescued the precocious leaf senescence of pat14-2, demonstrating that the role of PAT14 in suppressing SA signaling during age-dependent leaf senescence is evolutionarily conserved between dicots and monocots.
