Strigolactones Regulate Sugar Allocation to Control Rice Tillering and Root Development via the OsSPL14-OsSHR1-OsSWEET16 Pathway.
Article in Plant biotechnology journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Strigolactones (SLs) are root-to-shoot phytohormones that regulate tillering (branching) and root development. Sugar, as an essential energy substance and signalling molecule, plays a fundamental role in the growth and development of plants. However, the molecular mechanisms by which SL directly regulates sugar allocation to control tillering and root development are still not fully understood. Here, we found that OsSHR1 operates directly downstream of OsSPL14 within the SL signalling pathway, facilitating root elongation while inhibiting tillering and crown root development. The expression of OsSHR1 is stimulated by OsSPL3/12/14 in vivo, and D53 can interact with these SPL proteins to suppress their transcriptional activities. Interestingly, we further demonstrate that OsSHR1 can directly bind to the promoters of OsSWEET2a/4/16, which encode sugar transporters that can control the allocation of sugar in plant growth and development. This binding facilitates the expression of sugar transporters, which in turn regulate sugar allocation and enable the plant's response to SLs. The results indicate that via the OsSPL14-OsSHR1-OsSWEET16 pathway, SLs orchestrate the distribution of sugars to ensure their effectiveness in stimulating root elongation while simultaneously suppressing tillering and crown root formation in rice.
