Enhanced production of reducing sugars from transgenic rice expressing exo-glucanase under the control of a senescence-inducible promoter.

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
We generated transgenic rice plants that express EXG1 exo-glucanase under the control of a senescence-inducible promoter. When a GUS coding sequence was connected to a promoter region of STAY GREEN (SGR) gene of rice and introduced into rice, GUS activity was specifically observed along with senescence. When an EXG1 cDNA was connected to the SGR promoter and introduced into rice, higher cellulase activities were detected after senescence. The EXG1 transgenic plants showed enhanced enzymatic saccharification efficiencies after senescence, but no significant difference of saccharification efficiencies was observed before senescence. The saccharification efficiencies were correlated with the cellulase activities in the transgenic plants. The EXG1 transgenic plants showed neither morphological abnormality nor sterility, both of which were observed when EXG1 was constitutively overexpressed. These results indicate that expression of cell wall degrading enzymes such as cellulase by a senescence-inducible promoter is one of the ways to enhance the saccharification ability of cellulosic biomass without affecting plant growth for efficient production of biofuels.
