Oxalate production by Sclerotinia sclerotiorum deregulates guard cells during infection.

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
Oxalic acid is a virulence factor of several phytopathogenic fungi, including Sclerotinia sclerotiorum (Lib.) de Bary, but the detailed mechanisms by which oxalic acid affects host cells and tissues are not understood. We tested the hypothesis that oxalate induces foliar wilting during fungal infection by manipulating guard cells. Unlike uninfected leaves, stomatal pores of Vicia faba leaves infected with S. sclerotiorum are open at night. This cellular response appears to be dependent on oxalic acid because stomatal pores are partially closed when leaves are infected with an oxalate-deficient mutant of S. sclerotiorum. In contrast to oxalate-deficient S. sclerotiorum, wild-type fungus causes an increase in stomatal conductance and transpiration as well as a decrease in plant biomass. Green fluorescent protein-tagged S. sclerotiorum emerges through open stomata from the uninfected abaxial leaf surface for secondary colonization. Exogenous application of oxalic acid to the detached abaxial epidermis of V. faba leaves induces stomatal opening. Guard cells treated with oxalic acid accumulate potassium and break down starch, both of which are known to contribute to stomatal opening. Oxalate interferes with abscisic acid (ABA)-induced stomatal closure. The Arabidopsis (Arabidopsis thaliana) L. Heynh. mutants abi1, abi3, abi4, and aba2 are more susceptible to oxalate-deficient S. sclerotiorum than wild-type plants, suggesting that Sclerotinia resistance is dependent on ABA. We conclude that oxalate acts via (1) accumulation of osmotically active molecules to induce stomatal opening and (2) inhibition of ABA-induced stomatal closure.
