Genetic and epigenetic divergence among Arabidopsis thaliana Col-0 laboratory lineages since the 1950s
Plant Science Research WeeklyThe Arabidopsis thaliana Columbia-0 (Col-0) accession is often treated as a standard reference genotype shared by plant researchers worldwide. However, a new study by Tadros et al. shows that decades of independent propagation in different laboratories have left distinct genetic and epigenetic signatures…
Opinion: Non-model plants as windows into complex epigenetic adaptation
Plant Science Research WeeklyPlants thrive in constantly changing environments through remarkable trait plasticity, enabling rapid physiological and developmental adaptation to stress. Beyond immediate responses, chromatin regulation provides a mechanism for long-term stress memory via epigenetic changes, allowing plants to “remember”…
