Sugar acts as a regulatory signal on the wound-inducible expression of SbHRGP3::GUS in transgenic plants.
Article in Plant cell reports, 2003. 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
SbHRGP3 encodes an HRGP whose expression is correlated with the cessation of root elongation in soybean. The wound-inducible expression of SbHRGP3 interestingly requires sucrose although wounding alone induces the expression of many HRGP genes. To examine whether sugar serves as a specific signal on the wound-inducible expression or whether sugar is required to provide ATP, we examined SbHRGP3:: GUS expression in transgenic tobacco plants. Various oligosaccharides including non-metabolizable sugar induced SbHRGP3:: GUS expression in transgenic plants. The inhibitors of photosynthesis and of cellular respiration did not affect the wound-inducible expression of SbHRGP3:: GUS. However, the induction was significantly affected by PCMBS, an inhibitor of active apoplastic phloem loading of sucrose, suggesting that SbHRGP3:: GUS expression in phloem tissues requires translocated sucrose. We therefore propose that sugar acts as a specific regulatory signal on the wound-inducible expression of SbHRGP3, rather than acting as a simple provider of ATP.
