High-frequency biparental inheritance of plant mitochondria upon chilling stress and loss of a genome-degrading nuclease.
Article in Nature plants, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Mitochondria are inherited maternally in the vast majority of eukaryotes. Occasional transmission of paternal mitochondria (paternal leakage) can lead to heterochondriomy and recombination between maternal and paternal mitochondrial genomes. Despite its potential physiological and evolutionary consequences, the extent of paternal leakage and the cellular processes governing mitochondrial inheritance remain largely unknown. Here we have established a robust genetic screen to detect paternal mitochondrial inheritance in tobacco (Nicotiana tabacum). Our data reveal an unexpectedly high paternal transmission frequency of 0.18%, which increased markedly to 7.34% when the organellar exonuclease DPD1 was disrupted and pollen development occurred at low temperature. Notably, paternally transmitted mitochondria restored growth, development and male fertility in progeny that inherited dysfunctional mitochondria from the maternal parent. Together, our findings uncover molecular mechanisms underlying maternal mitochondrial inheritance, and highlight the potential of biparental transmission to rescue mitochondrial function and generate novel mitochondrial genotypes through recombination.
