Florigen-producing cells express FPF1-LIKE PROTEIN 1 to accelerate flowering and stem growth in Arabidopsis.
Article in Developmental cell, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Plants induce the expression of the florigen FLOWERING LOCUS T (FT) in response to seasonal changes. FT is expressed in a distinct subset of phloem companion cells in Arabidopsis. Using tissue-specific translatome analysis, we discovered that the FT-expressing cells also express FLOWERING PROMOTING FACTOR 1 (FPF1)-LIKE PROTEIN 1 (FLP1), specifically under long-day conditions with the red/far-red ratio of natural sunlight. The master regulator of FT, CONSTANS (CO), is essential for FLP1 expression, suggesting that FLP1 is involved in the photoperiod pathway. We show that FLP1 promotes early flowering independently of FT, is active in the shoot apical meristem, and induces the expression of SEPALLATA3 (SEP3), a key E-class homeotic gene. Unlike FT, FLP1 also facilitates inflorescence stem elongation. Our cumulative evidence suggests that the small FLP1 protein acts as a mobile signal like FT. Taken together, FLP1 accelerates flowering in parallel with FT and orchestrates flowering and stem elongation during the reproductive transition.
