The mirage of DNA methylation in transcriptional regulation of plants Links between DNA methylation and transcription remain difficult to generalize and are weak on genome-wide scales. Multiple lines of evidence suggest DNA methylation plays only a minor role in the r...

🧬Does DNA methylation really control gene expression in plants?
Our new paper challenges this assumption — showing that methylation and transcription often avoid one another rather than align. Why is that?

Epigenetic regulation of mycorrhizal symbioses: from plastic responses to transgenerational legacies Mycorrhizal symbioses represent one of the most widespread and ecologically significant plant–microbe interactions, shaping plant nutrition, stress resilience, and ecosystem functioning. Beyond their...

🧬How do mycorrhizal symbioses shape plant plasticity across generations? Epigenetic regulation may fine-tune these mutualisms, modulating plant responses and potentially transmitting adaptive legacies shaped by host lifespan and reproduction mode.⬇️

Stronger transgenerational plasticity in clonal compared to sexual offspring of Fragaria vesca: effects of drought, elevated temperature and CO2 AbstractBackground and Aims. Climate change threatens plant species, potentially exceeding their adaptive capacities. Plants may adapt to rapid environment

🧬Does DNA methylation inheritance differ in clonal and sexual offspring? In wild strawberry, we found higher methylation inheritance in clonal offspring linked to stronger transgenerational plasticity under climate stress.

Reversibility of sex changes in the plant kingdom: more important than we thought? Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought ...

🚨Just out! 🚨
Our new review explores how reversible sex changes in plants may be key players in plant evolution. Turns out, sex in plants isn't as fixed as we thought. Epigenetics and the environment can flip the script, even within one generation!
