An epidermis/papilla-specific oxalate oxidase-like protein in the defence response of barley attacked by the powdery mildew fungus.

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 cDNA clone of a defence response transcript was isolated from a library prepared from barley leaves expressing papilla resistance towards the powdery mildew fungus, Blumeria (syn. Erysiphe) graminis f.sp. hordei (Bgh). The 904 bp sequence encodes a 229 amino acid polypeptide with a putative signal peptide of 23 amino acids. After cleavage, the protein has a mass of 22.3 kDa and exhibits up to 60% amino acid identity to certain dicot proteins, and 46% amino acid identity to barley oxalate oxidase; therefore we designated it HvOxOLP (for Hordeum vulgare oxalate oxidase-like protein). Single-base substitutions among several cDNA and RACE clones demonstrate a gene of many copies. Both the transcript and protein accumulate from 3 h after inoculation with Bgh. The transcript level peaks at 18-24 h and subsequently decreases, whereas the protein level is stable from 24 h after inoculation. The accumulation patterns are independent of the outcome of the barley/powdery mildew interaction, unlike that of PR proteins, for example. The transcript accumulates specifically in the inoculated epidermal tissue. This temporal and spatial expression pattern suggests a very close relationship to papilla formation. Immunoblot analyses have facilitated a demonstration that HvOxOLP, like oxalate oxidase, is a water-soluble 100 kDa oligomeric protein. The oligomer is heat-stable and SDS-tolerant, and it can be denatured into a 25 kDa monomer. Attempts to demonstrate oxalate oxidase activity for this protein have failed. However, the relationships to oxalate oxidase suggests that HvOxOLP may be involved in H2O2 generation necessary for, for example, cross-linking of cell wall components during formation of papillae.
