Function and Application of the CRISPR-Cas System in the Plant Pathogen
Article in Applied and environmental microbiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Phage-based biocontrol is an emerging method for managing the plant pathogen Erwinia amylovora. Control of E. amylovora in North America is achieved chiefly through the application of streptomycin and has led to the development of streptomycin resistance. Resistant E. amylovora can be tracked through the analysis of CRISPR spacer sequences. An alternative to antibiotics are bacterial viruses, known as phages, which lyse their hosts during replication to control the bacterial population. Endogenous CRISPR-Cas systems act as phage resistance mechanisms however, preliminary genomic analysis suggests this activity is limited in E. amylovora. This leaves the functionality of the CRISPR-Cas system, any clade-based differences, and the impact which this system may have on phage-based biocontrol in question. In this study, the CRISPR arrays from 127 newly available genomic sequences of E. amylovora were analyzed through a novel bioinformatic pipeline. Through this, the Eastern and Western North American clades were shown to be incompatible with the current PCR-based approaches for tracking E. amylovora given the size and composition of their CRISPR arrays. Two artificial CRISPR arrays were designed to investigate the functionality of the CRISPR-Cas system in E. amylovora. This system was capable of curing a targeted plasmid and providing phage resistance but was not the source of phage resistance observed within the controls. This suggests that while the CRISPR-Cas system is an important defense mechanism for invasive plasmids, an as yet unidentified mechanism is the primary source of phage resistance in E. amylovora.
