Phospholipase A2beta mediates light-induced stomatal opening in Arabidopsis.
Article in Journal of experimental botany, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 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
Phospholipase A(2) (PLA(2)) catalyses the hydrolysis of phospholipids into lysophospholipids and free fatty acids. Physiological studies have indicated that PLA(2) is involved in stomatal movement. However, genetic evidence of a role of PLA(2) in guard cell signalling has not yet been reported. To identify PLA(2) gene(s) that is (are) involved in light-induced stomatal opening, stomatal movement was examined in Arabidopsis thaliana plants in which the expression of PLA(2) isoforms was reduced or knocked-out. Light-induced stomatal opening in PLA(2)alpha knockout plants did not differ from wild-type plants. Plants in which PLA(2)beta was silenced by RNA interference exhibited delayed light-induced stomatal opening, and this phenotype was reversed by exogenous lysophospholipids, which are products of PLA(2). Stomatal opening in transgenic plants that over-expressed PLA(2)beta was faster than wild-type plants. The expression of PLA(2)beta was localized to the endoplasmic reticulum of guard cells, and increased in response to light in the mature leaf. Aristolochic acid, which inhibits light-induced stomatal opening, inhibited the activity of purified PLA(2)beta. Collectively, these results provide evidence that PLA(2)beta is involved in light-induced stomatal opening in Arabidopsis.
