A multi-perspective analysis of the regulatory mechanisms governing pedicel abscission in tomato.
Review in Plant cell reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
key messageThis paper summarizes the molecular network regulating tomato pedicel abscission and proposes a multisignal integration framework for this regulatory process.
methodsTomato (Solanum lycopersicum L.) has emerged as a model plant for pedicel abscission studies due to its unique strengths, particularly the presence of a specialized abscission zone (AZ) that serves as the core regulatory node. Elucidating the regulatory mechanisms of pedicel abscission is crucial for improving crop stress resistance and yield. This paper summarizes recent progress in understanding the regulation of tomato pedicel abscission by environmental stresses, phytohormones, and transcription factors. For instance, environmental stress initiates the abscission program by disrupting the indoleacetic acid (IAA) gradient, inducing ethylene (ETH) bursts, and activating peptide hormone signaling pathways. The multilevel integrated regulation of the abscission process by a network of transcription factors is also systematically discussed. This regulation ensures the spatial and temporal coordination of AZ development, IAA transport, ETH response, and stress signaling. Despite significant advancements, several aspects remain to be explored in depth, including the dynamic interplay between environmental signals and endogenous abscission programs, the stress tolerance functions of core regulatory elements, and their ecological adaptations. This review comprehensively analyzes the molecular mechanisms of pedicel abscission in tomato, providing theoretical support and direction for crop resistance research.
