Epigenetic regulation of mycorrhizal symbioses: from plastic responses to transgenerational legacies

Gerson Beltrán-Torres, Henry J. De La Cruz, Stéphane Maury, Martina Janoušková et autres

Mycorrhizal symbioses represent one of the most widespread and ecologically significant plant-microbe interactions, shaping plant nutrition, stress resilience, and ecosystem functioning. Beyond their role in nutrient exchange and systemic defense, growing evidence suggests that these symbioses also influence plant plasticity within and …

Drought-Induced Epigenetic Memory in the Cambium of Poplar Trees persists and primes future stress responses

Alexandre Duplan, Yu Feng, Gwenvael LASKAR, Vincent Segura et autres

ABSTRACT Understanding how perennial plants such as trees perceive, integrate and memorize repeated environmental stresses like water deficit is crucial in the context of climate change. We investigated short-term and trans-annual memory of water deficit in cambium derived tissues of poplars ( …

Natural variation in chalcone isomerase defines a major locus controlling radial stem growth variation among Populus nigra populations

Harold Duruflé, Annabelle Déjardin, Véronique Jorge, Marie Pégard et autres

Poplar is a promising resource for wood production and the development of lignocellulosic biomass, but currently available varieties have not been optimized for these purposes. Therefore, it is critical to investigate the genetic variability and mechanisms underlying traits that affect biomass yield. …

Imputation strategy for population DNA methylation sequencing data

Alexandre Duplan, Shannon Brandt, Abel Garnier, Jörg Tost et autres

Background: DNA methylation is a central epigenetic mechanism involved in regulating gene expression and responses to environmental factors. Although it can sometimes be passed down through generations, its heritability remains variable depending on the species and biological context. These characteristics make it …

Genetic control of abiotic stress-related specialized metabolites in sunflower

Marco Moroldo, Nicolas Blanchet, Harold Duruflé, Stéphane Bernillon et autres

BACKGROUND: Abiotic stresses in plants include all the environmental conditions that significantly reduce yields, like drought and heat. One of the most significant effects they exert at the cellular level is the accumulation of reactive oxygen species, which cause extensive damage. Plants …
