Identification of a new pea gene, PsNlec1, encoding a lectin-like glycoprotein isolated from the symbiosomes of root nodules.

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 27-kD glycoprotein antigen recognized by monoclonal antibody MAC266 was purified from isolated symbiosomes derived from pea (Pisum sativum) root nodules containing Rhizobium. The N-terminal amino acid sequence was obtained, and the corresponding cDNA clone was isolated by a polymerase chain reaction-based strategy. The clone contained a single open reading frame, and the gene was termed PsNlec1. Phylogenetic analysis of 31 legume sequences showed that the PsNlec1 protein is related to the legume lectin family but belongs to a subgroup that is very different from pea seed lectin. Expression of the PsNlec1 transcript was much stronger in nodules than in other parts of the plant. It was found in both infected and uninfected cells in the central tissue of the nodule and in the stele of the root near the attachment point of the nodule. When uninfected pea seedlings were grown on medium containing nitrate, weak transcription of PsNlec1 was observed in the root system. The identification of PsNlec1 inside the symbiosome is consistent with the observation that legume lectins are generally vacuolar proteins that may serve as transient storage components.
