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

Plumbago auriculata L., a tropical evergreen, developed enhanced cold tolerance through long-term field acclimation, yet its molecular mechanisms remained unclear. Here, we identified PaMYBS3, a MYB transcription factor, as a key dual-function regulator during cold acclimation. Short-term artificial cold treatment induced PaMYBS3 expression and improved cold resistance. Overexpression of PaMYBS3 in Arabidopsis promoted growth but reduced freezing tolerance, while domain-mutant and VIGS-silenced lines exhibited inhibited growth and enhanced cold adaptation. Physiological assays revealed that PaMYBS3 enhances cold tolerance by modulating ROS balance, photosynthetic performance, and osmotic regulators, while suppressing growth through downregulation of auxin- and sugar-related genes, supporting a cold acclimation strategy that prioritizes survival over growth. Notably, PaMYBS3 regulated cold-responsive pathways independently of the classical CBF/DREB1-COR module, suggesting a CBF-independent cold tolerance mechanism. Our findings highlight PaMYBS3 as a central integrator of cold response and growth restraint, offering new insights into the adaptive strategies of tropical perennials under prolonged low temperature.
