Identification of a promoter region responsible for the senescence-specific expression of SAG12.

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
SAG12, an Arabidopsis gene encoding a cysteine protease, is expressed only in senescent tissues. Studies of the expression patterns of a variety of genes showing senescence-specific or senescence-preferential expression indicate that plant senescence involves multiple regulatory pathways. In this study it is shown that the expression of SAG12 is specifically activated by developmentally controlled senescence pathways but not by stress- or hormone-controlled pathways. Using SAG12 as a molecular marker for the study of developmental senescence, we show that cytokinin, auxin, and sugars can repress developmental senescence at the molecular level. Studies using promoter deletions and recombination of promoter fragments indicate that a highly conserved region of the SAG12 promoter is responsible for senescence-specific regulation, while at least two other regions of the SAG12 promoter are important for full promoter activity. Extracts from young and senescent Arabidopsis leaves contain factors that exhibit differential binding to the senescence-responsive promoter element.
