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

The current consensus is that plant responses to canopy shade involve the perception of low red to far-red ratios (R:FRs) by phytochrome B (phyB), which leads to the direct activation of auxin synthesis genes by PHYTOCHROME INTERACTING FACTORs (PIFs). In addition to its effect on R:FRs, shade also reduces irradiance, but whether shade-induced drops in irradiance affect phyB activity has not been demonstrated. To address this issue, we investigated whether irradiance and R:FRs have similar effects on the nuclear distribution of phyB in petiole cells of light-grown plants. Under high-irradiance white light, phyB formed large nuclear bodies. Lowering irradiance without changing R:FRs or lowering R:FRs by adding far-red light led to the appearance of small nuclear bodies containing phyB. Large nuclear bodies remained but with some concomitant reduction in diameter. The appearance of small nuclear bodies was rapid, stable, and reversible upon the return to high irradiance and high R:FRs. High levels of red light but not of blue light were enough to restrain the formation of small phyB nuclear bodies. Irradiance was effective within the range found in natural canopies and even under relatively low R:FRs. The promotion of leaf hyponasty by lowering irradiance was impaired in phyB and pif mutants, as previously reported for the response to R:FRs. The expression of auxin-related genes showed a similar hierarchy of response to low R:FRs and low irradiance. We propose that phyB is able to perceive not only the low R:FRs, but also the low irradiance of shade.
