Spatial expression of CLAVATA3 in the shoot apical meristem suggests it is not a stem cell marker in soybean.

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
CLAVATA3 (CLV3), a stem cell marker in Arabidopsis thaliana, encodes a secreted peptide that maintains the stem cell population within the shoot apical meristem. This work investigated the CLV3 orthologue in a major legume crop, soybean (GmCLV3). Instead of being expressed in the three outermost layers of the meristem as in Arabidopsis, GmCLV3 was expressed deeper in the central zone beneath the fourth layer (L4) of the meristem, overlapping with the expression of soybean WUSCHEL. Subsequent investigation using an alternative stem cell marker (GmLOG1) revealed its expression within layers L2-L4, indicating that GmCLV3 is not a stem cell marker. Overexpression studies of GmCLV3 in Arabidopsis and complementation of clv3-2 mutant suggest similar functional capacity to that of Arabidopsis CLV3. The expression of soybean CLV1, which encodes a receptor for CLV3 in Arabidopsis, was not detectable in the central zone of the meristem via reverse-transcription PCR analysis of amplified RNA from laser-microdissected samples or in situ, implicating a diverged pathway in soybean. This study also reports the novel expression of GmLOG1 in initials of axillary meristem in the boundary region between the SAM and developing leaf primordia, before the expression of GmWUS or GmCLV3, indicating cytokinin as one of the earliest signals in initiating and specifying the stem cell population.
