Fungal cellulase is an elicitor but its enzymatic activity is not required for its elicitor activity.

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
Plant-pathogenic fungi produce cellulases. However, little information is available on cellulase as an elicitor in plant-pathogen interactions. Here, an endocellulase (EG1) was isolated from Rhizoctonia solani. It contains a putative protein of 227 amino acids with a signal peptide and a family-45 glycosyl hydrolase domain. Its aspartic acid (Asp) residue at position 32 was changed to alanine (Ala), resulting in full loss of its catalytic activity. Wild-type and mutated forms of the endoglucanase were expressed in yeast and purified to homogeneity. The purified wild-type and mutant forms induced cell death in maize, tobacco and Arabidopsis leaves, and the transcription of three defence marker genes in maize and tobacco and 10 genes related to defence responses in maize. Moreover, they also induced the accumulation of reactive oxygen species (ROS), medium alkalinization, Ca(2+) accumulation and ethylene biosynthesis of suspension-cultured tobacco cells. Similarly, production of the EG1 wild-type and mutated forms in tobacco induced cell death using the Potato virus X (PVX) expression system. In vivo, expression of EG1 was also related to cell death during infection of maize by R. solani. These results provide direct evidence that the endoglucanase is an elicitor, but its enzymatic activity is not required for its elicitor activity.
