elighted to have shared this article about the role of lncRNAs in stress response with the amazing team of @bleinthomas.bsky.social and Céline Charon. I am super grateful to Pablo Manavella for inviting us to write this review, and to the reviewers that helped us to improve the article.

🌱 From environmental responses to adaptation: the roles of plant lncRNAs 🧬🍃 Dive into the latest publication from the REGARN team. @traubenik.bsky.social, Céline Charon and @bleinthomas.bsky.social describe the roles of plant lncRNAs in responding to environmental challenges doi.org/10.1093/plph...

Schematic figure conceptualizing the roles of long non-coding RNAs (lncRNAs) in stress responses in plants.
A. LncRNAs are key players allowing plants to cope with stress. B. Stress memory. Stress triggers plant defenses that are essential for survival. Repeated stress exposure and recovery actions develop stress memory (priming) to overcome repeated exposure to stress and improve plant survival, in a process where lncRNAs may play an important role. C. Conservation of lncRNAs in plant stress adaptation. LncRNAs exhibit differences in expression between natural accessions in response to stress, leading to their adaptation to different environments. Specific lncRNAs mediate stress response in Ecotype A (left) leading to plant stress tolerance, while they are absent or silenced in Ecotype B (right), leading to plant stress sensitivity.
