Stronger transgenerational plasticity in clonal compared to sexual offspring of Fragaria vesca: effects of drought, elevated temperature and CO2.

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
BACKGROUND AND
aimsClimate change threatens plant species, potentially exceeding their adaptive capacities. Plants may adapt to rapid environmental changes through transgenerational plasticity (TGP), where adaptive traits are passed to their offspring via proteins, hormones and epigenetic modifications such as DNA methylation. The extent of TGP and its ecological implications may differ between sexual and clonal reproductive modes due to differences in the inheritance of DNA methylation and provisioning. However, it remains unclear whether TGP differs between these reproductive modes and the role of DNA methylation. Addressing this gap is crucial, as higher TGP in clonal propagation could compensate for low genetic variation and help these plants in adapting to rapid environmental changes.
methodsWe assessed the adaptive potential of woodland strawberry (Fragaria vesca), a widely distributed herb with both clonal and sexual reproduction, in response to environmental conditions expected by the end of the 21st century: a temperature rise of 4 °C, a 400 ppm rise in atmospheric CO2 and periodic droughts. We quantified ecologically relevant phenotypic traits and examined whole-genome DNA methylation patterns in parents and their clonal and sexual offspring. KEY
resultsWe found evidence for TGP induced by the parental environment, with a stronger overall effect observed in clonal compared to sexual offspring. Specifically, parental exposure to current temperature and CO2 conditions prompted adaptive TGP, particularly in clonal offspring. Additionally, adaptive TGP was observed exclusively in clonal offspring in response to a combination of elevated parental temperature and drought conditions. Finally, we found a higher inheritance of DNA methylation marks in clonal than in sexual offspring.
conclusionsThese results suggest that while TGP via DNA methylation can influence clonal plant adaptation to future conditions, it remains uncertain whether this influence will consistently result in adaptive outcomes. Moreover, TGP would probably be more important in clonal than in sexual reproduction.
