ELD1 mediates photoperiodic flowering via OsCCA1 alternative splicing and interacts with phytochrome signaling in rice.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Photoperiodic flowering in plants is orchestrated by the dynamic interaction between light signals and the endogenous circadian clock, but how light signals integrate into the clock remains to be fully elucidated. Here, we identify ELD1, a CCHC-type zinc finger protein that is essential for rice embryo survival. Notably, partial loss of ELD1 function results in early flowering under long-day conditions. Further investigations demonstrate that ELD1 physically interacts with OsNKAP, an orthologue of mammal NF-κB activating protein, as well as core splicing factors to regulate the splicing profile of OsCCA1, a core oscillator of the circadian clock. Molecular and genetic evidence indicate that OsCCA1 is the primary target of ELD1 in controlling flowering time. Additionally, ELD1 interacts with photoactivated phyB, mediating red-light-regulated alternative splicing of OsCCA1. Collectively, our findings establish a molecular connection between light signaling and the circadian clock, with ELD1 modulating OsCCA1 alternative splicing to control photoperiodic flowering.
