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

Seasonal growth modulation is a key adaptive trait in perennials that supports overwinter survival. During winter, many perennials adopt a rosette growth habit by suppressing both vegetative extension and flowering, but the mechanism that coordinates these two distinct developmental programs remains unclear. Here, we show that prolonged chilling primarily acts at the shoot apex to confer extension growth and flowering competence in chrysanthemum (Chrysanthemum morifolium). Long-term chilling is accompanied by marked changes in gene expression in the rib zone of the shoot apex. Notably, the expression of CmDREBa is associated with the transition from extension growth to rosette growth. Chilling induces CmDREBa expression, which suppresses both extension growth and flowering; when temperatures rise, CmDREBa expression declines, allowing both processes to resume. CmDREBa directly induces the expression of MADS AFFECTING FLOWERING (MAF) genes, which in turn promote rosette growth. Together, these findings identify CmDREBa as a key regulator of chilling-responsive seasonal growth.
