Bryophytes are a widespread group of land plants that occupy nearly all biomes, yet their genetics and evolutionary history have long remained underexplored. Now, a study that generates extensive genomic data for bryophytes highlights de novo gene formation and horizontal gene transfer as key forces that shape bryophyte diversity and adaptation.

Human centromeres contain a small chromatin region with low levels of DNA cytosine methylation that resides with CENP-A. Salinas-Luypaert et al. find a role of DNA methylation in maintaining the size and function of centromeres by controlling the binding affinity of key centromere components.

Tamoxifen is an essential drug in breast cancer therapy. Unlike prevailing models of therapy-related tumorigenesis, tamoxifen acts by directly activating the PI3K pathway, bypassing the need for mutat...

We combined CRISPR activation of all 1,836 known human transcription factors with high-throughput Perturb-seq to recreate the diverse transcriptional states occupied by fibroblasts in vivo. Our study ...
