Expression of a fungal endochitinase gene in transgenic tomato and tobacco results in enhanced tolerance to fungal pathogens.

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
Development of transgenic Nicotiana tabacum and Lycopersicon esculentum expressing an endochitinase (ech42) gene from biocontrol fungus Trichoderma virens using Agrobacterium-mediated genetic transformation is reported in this paper. Integration of transgene in the genome of transgenic plants was demonstrated using polymerase chain reaction and Southern-blot hybridization, while expression was ascertained by reverse transcription polymerase chain reaction. Histochemical analysis confirmed the expression of GUS enzyme in transformed shoots. Levels of endochitinase enzyme in transgenic plants were found to be up to 10 fold higher compared to control plants. Endochitinase enzyme of 42 kDa was also visualized on SDS-PAGE gel using fluorimetric zymogram in transgenic plants. Endochitinase activity was found to be higher in leaf and stem than the root tissue in transgenic tomato plants. Transgenic lines of both plants showed enhanced resistance to fungal pathogens and a strong negative correlation was found between expression level of endochitinase enzyme and size of disease lesions. Inheritance of transgene, expression and resistance to fungal pathogens of T1 transgenic tobacco lines was also analysed. The results of the present studies show that ech42 is a promising candidate gene for developing fungal disease resistance in tomato plants.
