Characterization of a Sorghum bicolor gene family encoding putative protein kinases with a high similarity to the yeast SNF1 protein kinase.
Article in Plant molecular biology, 1998. 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
C4 photosynthesis is functionally dependent on metabolic interactions between mesophyll and bundle-sheath cells. Although the C4 cycle is biochemically well understood many aspects of the regulation of enzyme activities, gene expression and cell differentiation are elusive. Protein kinases are likely involved in these regulatory processes providing links to hormonal, metabolic and developmental signal transduction pathways. We have identified several protein kinases that are differentially expressed in mesophyll and bundle-sheath cells of the C4 plant Sorghum bicolor. Here we describe the characterization of two putative protein kinases that show high similarity to the SNF1/AMPK family of protein serine/threonine kinases. The mRNA of both kinases accumulates to much higher levels in mesophyll cells than in the bundle-sheath and can also be detected in root tissue. Complementation experiments with a snf1 mutant of Saccharomyces cerevisiae indicate that the S. bicolor protein kinase SNFL1 does not represent a functional homologue of the yeast SNF1 protein kinase.
