The polyamine spermine rescues Arabidopsis from salinity and drought stresses.

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
There are accumulating reports that polyamines are involved in abiotic stress response. However, the role played by the polyamines is not fully elucidated. In the present studies, we assessed whether spermine among the polyamines plays a certain role against high salt and drought stresses using an Arabidopsis (acl5/spms) mutant plant that does not produce spermine, and found that it was hypersensitive to those stresses. In each case the hypersensitive phenotype was mitigated by application of exogenous spermine. The spermine-deficient mutant plants also showed a phenotype resembling Ca(2+)-deficiency. The NaCl-hypersensitivity and Ca(2+)-deficiency of acl5/spms double-knockout mutant resembled the phenotypes displayed by the AtGluR2- and CAX1-overexpressing transgenic plants. The two latter genes encode a glutamate receptor-type, Ca(2+)-ion influx channel at cytoplasmic membrane and a vacuolar Ca(2+)/H(+) antiporter, respectively. The data suggest that regulated expression of the Ca(2+)-pathway members is critical to adapt to those stresses, and that spermine plays a certain role to control the stress-induced Ca(2+) dynamics. Incorporating the current information from the literature, especially regarding action of polyamines on various ion channels, we present models describing a defensive role of spermine in high salt and drought stresses in Arabidopsis.
