Molecular characterization of a novel tobacco pathogenesis-related (PR) protein: a new plant chitinase/lysozyme.
Article in Molecular & general genetics : MGG, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
A new PR (pathogenesis-related) protein was isolated from tobacco leaves (Nicotiana tabacum cv. Samsun NN), reacting hypersensitively to tobacco mosaic virus (TMV), by zinc chelate chromatography and was therefore named Pz. Its reactivity toward several lectins indicated the presence of bound sugar residues. From the amino acid sequence of tryptic peptides, Oligonucleotide primers were derived which allowed the synthesis of Pz cDNA by PCR. Using this cDNA as probe, near full-length clones were isolated from a library made from poly(A)+ RNA purified from TMV-infected leaves. Sequence analysis revealed similarities with chitinases/lysozymes of various origins and the purified protein was, indeed, shown to hydrolyse different N-acetylglucosamine-containing substrates. Comparison of peptide and cDNA sequences indicated that Pz protein is synthesized as a pre-pro-protein, a seven-amino acid C-terminal peptide probably being involved in the vacuolar targeting of the protein. Pz mRNA and protein were demonstrated to accumulate strongly in TMV-infected tobacco leaves. Pz transcripts were also found in various tissues of healthy plants, indicating that Pz gene expression is developmentally regulated.
