Gibberellin signalling mediates nucleocytoplasmic trafficking of Sucrose Synthase 1 to regulate the drought tolerance in rice.
Article in Plant biotechnology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
The Green Revolution (GR) has substantially improved cereal crop yields and enhanced adaptation to diverse environmental challenges. However, the molecular and cellular mechanisms involving GR-related genes that regulate drought tolerance in plants remain largely unclear. Here, we reveal that the gibberellin (GA) signalling repressor SLENDER RICE 1 (SLR1) negatively regulates the abundance of the dehydration-responsive protein OsBURP3 to enhance drought tolerance in rice. OsBURP3 facilitates the translocation of Sucrose Synthase 1 (OsSUS1), from the cytosol to the nucleus, thereby decreasing the sucrose content. Mutation of OsBURP3 reduces the nucleus accumulation of OsSUS1 to enhance drought tolerance. SLR1 also competitively associates with OsBURP3 in the nucleus to release OsSUS1 back into the cytosol, resulting in elevated sucrose content. Cytological evidences confirm that sucrose contributes to the fine-tuning of the stomata aperture in rice leaves. Collectively, these findings provide a comprehensive framework for understanding the role of GA in regulating drought tolerance by mediating sucrose metabolism in crops.
