Epigenetic clocks in plants: uncovering DNA methylation decay in aging
Plant Science Research WeeklyWhat if plants could teach us about aging? Understanding how and why living organisms age is a fundamental question in biology and medicine. While most research focuses on humans, the model plant Arabidopsis thaliana offers unique insights into how organisms age. In a recent study, Dai et al. analyzed…
SAM-seq: A novel approach for unraveling plant epigenetic complexity
Plant Science Research WeeklyThe complex interplay between nucleosome positioning, DNA methylation, and chromatin accessibility is crucial for genome regulation in eukaryotic organisms. However, current chromatin profiling methods, which rely on short-read sequencing, fail to characterize highly repetitive genomic regions and cannot…
