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 endosperm of cereal grains feeds the entire world as a major food supply; however, little is known about its defence response during endosperm development. The Inducer of CBF Expression 1 (ICE1) is a well-known regulator of cold tolerance in plants. ICE1 has a monocot-specific homologue that is preferentially expressed in cereal endosperms but with an unclear regulatory function. Here we characterized the function of monocot-specific ZmICE1a, which is expressed in the entire endosperm, with a predominant expression in its peripheral regions, including the aleurone layer, subaleurone layer and basal endosperm transfer layer in maize (Zea mays). Loss of function of ZmICE1a reduced starch content and kernel weight. RNA sequencing and CUT&Tag-seq analyses revealed that ZmICE1a positively regulates genes in starch synthesis while negatively regulating genes in aleurone layer-specific defence and the synthesis of indole-3-acetic acid and jasmonic acid (JA). Exogenous indole-3-acetic acid and JA both induce the expression of numerous defence genes, which show distinct spatial-specific expression in the basal endosperm transfer layer and subaleurone layer, respectively. Moreover, we dissected a JA-ZmJAZ9-ZmICE1a-MPI signalling axis involved in JA-mediated defence regulation. Overall, our study revealed ZmICE1a as a key regulator of endosperm defence response and a coordinator of the defence-storage trade-off in endosperm development.
