Sugar regulates mRNA abundance of H(+)-ATPase gene family members in tomato.
Article in Plant physiology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
The plant plasma membrane H(+)-ATPase energizes the secondary uptake of nutrients and may facilitate cell expansion by acidifying the cell wall. In yeast, Glc stimulates the accumulation of H(+)-ATPase mRNA, and the growth rate supported by various sugars is correlated with H(+)-ATPase protein abundance. Expression of three H(+)-ATPase genes, LHA1, LHA2, and LHA4, was previously detected in tomato (Lycopersicon esculentum). We have characterized the sequence of the LHA4 gene and examined the expression of these three tomato H(+)-ATPase genes in growing tissues and in response to exogenous sugars. LHA4 is a member of the H(+)-ATPase subfamily, including the Arabidopsis thaliana genes AHA1, AHA2, and AHA3. The 5' untranslated region of the deduced LHA4 cDNA contains a short, open reading frame very similar to that in the Nicotiana plumbaginifolia gene PMA1. LHA4 transcript abundance in seedlings is correlated with cell growth, being 2.5 times greater in hypocotyls of dark- versus light-grown plants. The accumulation of both LHA4 and LHA2 mRNAs is induced by the addition of exogenous sugars and this induction appears to be dependent on sugar uptake and metabolism, because mannitol and 3-O-methylglucose do not stimulate mRNA accumulation. These results suggest that the induction of expression of H(+)-ATPase genes by metabolizable sugars may be part of a generalized cellular response to increased cell growth and metabolism promoted by the availability of an abundant carbon source.
