KRP3 Stability Controls Rice Plant Architecture and Productivity via MPK3-Mediated Phosphorylation.
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 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
Yield is a critical agronomic trait in cereal crops, shaped by factors like tiller and seed number, and seed weight. Understanding the factors governing these traits will help in improving the yield of plants. In this study, we identified an orphan gene, KRP3, belonging to cereal crops as a key regulator of rice plant architecture. Altered KRP3 protein homeostasis affected plant height, tiller number, and seed production, highlighting its role in maintaining rice plant vigor and productivity. The stability of the KRP3 protein is positively regulated by MPK3-mediated phosphorylation, as unphosphorylated KRP3 is targeted for degradation via the ubiquitin-proteasome pathway. Our findings reveal that the identified MPK3-KRP3 module operates as an S-phase checkpoint, modulating the pace of cell division in the actively dividing zones and maintaining a balance between cell division and elongation. These findings provide valuable insights for improving plant growth and grain yield in rice.
