Maternal epigenetic regulation of embryonic patterning in plants.
Article in Nature plants, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Embryogenesis occurs within a specialized microenvironment established by maternal tissues that has long been thought to be crucial for supporting embryonic development. However, the maternal epigenetic mechanisms that regulate offspring development remain unclear. Here we profiled the H3K27me3 landscape in maternal integuments and demonstrated that epigenetic changes in maternal tissues shape embryonic patterning. Dynamic changes in H3K27me3 in the integuments are crucial for the activation of the auxin-transport genes AUX1 and LAX1, which allow auxin to accumulate in the micropylar integuments to which the embryo attaches. Deficiencies in H3K27me3 demethylase activity or AUX1/LAX1 expression reduce auxin levels in the micropylar integuments. This disrupts maternal-to-embryo auxin transport, leading to reduced auxin levels in the embryo and thus perturbing embryonic patterning. Our findings reveal a previously unrecognized mechanism of maternal epigenetic regulation that governs embryonic patterning.
