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

In C(4) plants, photorespiration is decreased relative to C(3) plants. However, it remains unclear how much photorespiratory capacity C(4) leaf tissues actually have. We thoroughly investigated the quantitative distribution of photorespiratory organelles and the immunogold localization of the P protein of glycine decarboxylase (GDC) in mesophyll (M) and bundle sheath (BS) cells of various C(4) grass species. Specific differences occurred in the proportions of mitochondria and peroxisomes in the BS cells (relative to the M cells) in photosynthetic tissues surrounding a vein: lower in the NADP-malic enzyme (NADP-ME) species having poorly formed grana in the BS chloroplasts, and higher in the NAD-malic enzyme (NAD-ME) and phosphoenolpyruvate carboxykinase (PCK) species having well developed grana. In all C(4) species, GDC was localized mainly in the BS mitochondria. When the total amounts of GDC in the BS mitochondria per unit leaf width were estimated from the immunogold labeling density and the quantity of mitochondria, the BSs of NADP-ME species contained less GDC than those of NAD-ME or PCK species. This trend was also verified by immunoblot analysis of leaf soluble protein. There was a high positive correlation between the degree of granal development (granal index) in the BS chloroplasts and the total amount of GDC in the BS mitochondria. The variations in the structural and biochemical features involved in photorespiration found among C(4) species might reflect differences in the O(2)/CO(2) partial pressure and in the potential photorespiratory capacity of the BS cells.
