1 · What the graph read from it

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.

2 · The registry

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

We have examined the characteristics of Ca(2+)-dependent phospholipid-binding proteins (annexins) in maize (Zea mays L.) coleoptiles and tip-growing pollen tubes of Lilium longiflorum. In maize, there are three such proteins, p35, p33, and p23. Partial sequence analysis reveals that peptides from p35 and p33 have identity to members of the annexin family of animal proteins and to annexins from tomato. Interestingly, multiple sequence alignments reveal that the domain responsible for Ca(2+) binding in animal annexins is not conserved in these plant peptide sequences. Although p33 and p35 share the annexin characteristic of binding to membrane lipid, unlike annexins II and VI they do not associate with detergent-insoluble cytoskeletal proteins or with F-actin from either plants or animals. Immunoblotting with antiserum raised to p33/p35 from maize reveals that cross-reactive polypeptides of 33 to 35 kilodaltons are also present in protein extracts from pollen tubes of L. longiflorum. Immunolocalization at the light microscope level suggests that these proteins are predominantly confined to the nongranular zone at the tube tip, a region rich in secretory vesicles. Our hypothesis that plant annexins mediate exocytotic events is supported by the finding that p23, p33, and p35 bind to these secretory vesicles in a Ca(2+)-dependent manner.
