Salicylic acid inhibits V-ATPase activity and restricts cell elongation.

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
While the role of salicylic acid (SA) in plant defence has been investigated for decades, its role in regulating plant growth and development has only come into focus recently. SA application inhibits growth independently of the established "Nonexpressor of Pathogenesis Related" (NPR) receptors. However, the underlying mechanism at the cellular level remains largely elusive. Here, we show that SA induces changes in vacuolar morphology and a significant increase in vacuolar pH in Arabidopsis (Arabidopsis thaliana). We demonstrate SA-mediated inhibition of V-ATPase activity, which is confirmed by experiments using the V-ATPase mutant vha-a2 vha-a3. The observed effects seem to be independent of the phytohormone auxin, which has been reported to crosstalk with SA. By inhibiting V-ATPase activity, SA impacts basic cellular functions such as vesicle trafficking and/or nutrient storage, affecting cell size and growth. Our results reveal a NPR-independent mechanism that attenuates growth, potentially reallocating resources to enhance plant robustness and promote endurance during environmental stresses.
