Signal peptide peptidases are expressed in the shoot apex of rice, localized to the endoplasmic reticulum.
Article in Plant cell reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Signal peptide peptidase (SPP) is a multi-transmembrane aspartic proteinase involved in regulated intramembrane proteolysis, which is implicated in fundamental life processes such as immunological response, cell signaling, tissue differentiation, and embryogenesis. In this study, we identified two rice SPPs: OsSPP1 and OsSPP2. Green fluorescent protein-fused OsSPP1 and OsSPP2 were localized to the ER in cultured plant cells. In situ hybridization showed that OsSPPs were strongly expressed in vegetative shoot apex, young panicle, developing panicle, and the early developing florets. Undifferentiated cells, which have the potential to differentiate into all of the aerial parts of the plant are presented in the shoot apex. OsSPPs are located in both the undifferentiated cells, and the early differentiated cells at the shoot apex. These results suggest that rice SPPs have an important function in differentiation and development at the shoot apex. The expression of the shoot apex and ER localization is equal to dicot Arabidopsis thaliana, and will have common crucial roles in plant.
