DNA hypomethylation of the host tree impairs interaction with mutualistic ectomycorrhizal fungus

Julien Vigneaud et al.

Summary: By manipulating the expression level of DNA methylation regulators in poplar trees, this study reveals the involvement of DNA methylation in regulating tree-fungus mutualistic interactions. Lower DNA methylation levels in poplar trees lead to reduced mycorrhizal formation and alterations in both plant and fungal genomes. These findings highlight the central role of DNA methylation in various pathways essential for ectomycorrhizal formation.

Coordinated Epigenetic Regulation in Plants: A Potent Managerial Tool to Conquer Biotic Stress

Chien-Yu Huang et al.

Summary: Plants have evolved phenotypic plasticity to combat pathogens and pests through epigenetic regulation. This regulation involves changes in DNA methylation, histone modification, and chromatin structures, which may be inherited by future generations. Understanding the mechanisms of epigenetic regulation is important for developing effective and eco-friendly strategies for crop protection.

Epigenetics: a catalyst of plant immunity against pathogens

Adam Hannan Parker et al.

Summary: The plant immune system protects against pests and diseases by recognizing stress-related molecular patterns, and this induced resistance can be transmitted to following generations. Pathogen infections can shape the plant immune system through epigenetic responses, while stress-induced epigenetic diversity may promote Darwinian evolution.

Crosstalk among pathways to generate DNA methylome

Taiko Kim To et al.

Summary: Cytosine is methylated in different ways in plant genomes, and recent studies have uncovered interaction between different methylation patterns. The role of linker histone H1 and variants of histone H2A in DNA methylation dynamics is becoming clearer. These new findings provide further insights into the mechanisms of DNA methylome formation.

Epigenetics in plant organismic interactions

Daniela Ramos-Cruz et al.

Summary: Plants are the central hubs of organismic interactions, constantly engaging in beneficial or competitive exchanges with various organisms. In order to establish and maintain these interactions, as well as defend against pathogens and herbivores, plants have evolved intricate regulatory mechanisms, with epigenetic mechanisms emerging as an additional regulatory entity. This review highlights recent advances in understanding the contribution of various epigenetic components and diversity to plant-organismic interactions.

RNAi suppression of DNA methylation affects the drought stress response and genome integrity in transgenic poplar

Mamadou D. Sow et al.

Summary: Trees, as long-lived organisms, adapt to their environments through epigenetic mechanisms, with DNA methylation playing a key role in regulating genes involved in hormone-related stress responses and maintaining genome integrity. Research on poplar trees with downregulated DDM1 gene showed that DNA methylation coordinates genomic and physiological responses to moderate water deficit, with hypomethylation under drought conditions leading to increased mobility of transposable elements.
