High-temperature-induced FKF1 accumulation promotes flowering through the dispersion of GI and degradation of SVP.
Article in Nature plants, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Floral transition is influenced by photoperiod and ambient temperature, which are integrated to modulate development via a molecular mechanism that remains to be elucidated. Here we demonstrate that the F-box protein FLAVIN-BINDING, KELCH REPEAT, F-BOX 1 (FKF1) and its interacting partner GIGANTEA (GI), central regulators of photoperiodic flowering, target SHORT VEGETATIVE PHASE (SVP) for 26S-proteasome-dependent degradation to regulate the temperature-responsive developmental transition to flowering. At low temperatures, GI is sequestered in liquid-like nuclear condensates. By contrast, FKF1 accumulates at high temperatures and releases GI from condensates to form a nuclear-dispersed FKF1-GI complex, leading to SVP degradation under short-day conditions. Temperature sensitivity is significantly reduced in fkf1-t, gi-2 and fkf1-2 gi-2 mutants. We propose that the FKF1-GI complex mediates the proteolysis of a floral repressor via reversible liquid-liquid phase separation to accelerate floral transition at high temperatures.
