Human populations across a vast area in northern Eurasia, from Fennoscandia to Chukotka, share a distinct genetic component often referred to as the Siberian ancestry. Most enriched in present-day Samoyedic-speaking populations such as Nganasans, its origins and history still remain elusive despite the growing list of ancient and present-day genomes from Siberia. Here, we reanalyze published ancient and present-day Siberian genomes focusing on the Baikal and Yakutia, resolving key questions regarding their genetic history.

- This study investigates differences in DNA methylation during Arabidopsis embryogenesis and germination between two ecotypes: Columbia-0 (Col) and Cape Verde Island (Cvi), focusing on how these differences arise due to small RNA-directed DNA methylation.
- Utilizing comparative pairwise multi-omics dynamics, the researchers found that methylation patterns are ecotype-dependent, with significant variations in genic CG methylation, particularly in regions unique to the Col ecotype, which were also associated with transposable elements.
- The study confirms that the RdDM (RNA-directed DNA methylation) pathway plays a crucial role in regulating methylation levels both in ecotype-specific regions and in differentially
