VvERF045 Integrates Ethylene, Brassinosteroid and Abscisic Acid Pathways to Orchestrate Anthocyanin Biosynthesis in Grapevine.
Article in Plant biotechnology journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Anthocyanin biosynthesis in non-climacteric grape berries is regulated through coordinated phytohormonal signalling networks. However, the precise mechanisms by which abscisic acid (ABA), brassinosteroids (BRs) and ethylene (ET) synergistically modulate this process remain unclear. In this study, we identified the ET-responsive transcription factor VvERF045 as a critical integrator mediating the crosstalk among ET, BR and ABA pathways, thereby regulating anthocyanin biosynthesis. Mechanistically, VvERF045 physically interacts with its R2R3-MYB partner, VvMYB62, to co-activate the structural genes (SGs) involved in anthocyanin, BR and ABA biosynthesis pathways, including VvUFGT, VvDFR, VvDWF4, VvCPD, VvZEP/ABA1, thus collaboratively redirecting metabolic resources toward the production of anthocyanin, BR and ABA, respectively. Notably, ET significantly enhances the activity of VvERF045, suggesting a potential regulatory hierarchy wherein both BR-dependent and ABA-dependent berry pigmentation may be contingent on upstream ET perception. Collectively, our findings provide insights into how non-climacteric grape fruits temporally coordinate phytohormone pathways for colouration, revealing VvERF045 as a central regulator that bridges ET sensing to BR-mediated and ABA-mediated anthocyanin accumulation.
