Overexpression of OsSTP1 increases grain yield via enhancing carbohydrate metabolism and transport in rice.
Article in Planta, 2024. 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
MAIN
conclusionOverexpression of OsSTP1 enhances the non-structural carbohydrate remobilization in the source, starch accumulation in grains, and the transportation of carbohydrates from source to sink during the filling stage. The sugar transporter protein (STP) is the best-characterized subfamily of the monosaccharide transporter (MST) family and plays critical roles in regulating plant stress tolerance, growth, and development. However, the role of STPs in regulating rice yield is poorly understood. In this study, we report that compared with Taipei 309, overexpression of OsSTP1 can achieve higher rice yield. We demonstrate that OsSTP1 mRNA levels are higher than those of the other seven STPs in mixed samples of leaf sheaths, stems, and nodes at 12 days after pollination (DAP). OsSTP1 is prominently expressed in the leaf sheaths, stems, and nodes at the grain filling stage. Subcellular localization analysis revealed that OsSTP1 is localized in the plasma membrane. Overexpression of OsSTP1 increased the activities of amylase (AMY) and sucrose phosphate synthase (SPS) in mixed samples of leaf sheaths, stems, and nodes at 12 DAP, the sucrose content of the phloem exudate, and accumulation of soluble sugars and starch in panicles, ultimately increasing seed-setting rates and grain yields in the Taipei 309 cultivar. These findings indicate that overexpression of OsSTP1 can improve grain yield by synergistically promoting non-structural carbohydrate (NSC) remobilization and transportation.
