Synopsis. “Sex” is a compound of many different concepts that contribute to a multiplicity of meanings. As a result, “sex” appears in a wide range of scien

Some avocados are female in the morning and male in the afternoon, while others are on the opposite schedule. How avocados do this has been unclear — until now, thanks to a UC Davis study.

Degenerate sex chromosomes ( e.g., the Y or W) remain among the most difficult regions of eukaryotic genomes to assemble because they are highly repetitive and structurally complex. While many recent ...

High-quality genome assemblies from multiple plant species reveal different paths of evolution in supergenes.

De novo gene origination from noncoding regions is a major source of genetic innovation. Dong et al. [1] (Nat. Genet. 2025; 57:2562–2569) reveal that bryophytes harbor an exceptionally high abundance of such genes, establishing them as a new and key system for studying the mechanisms and evolutionary consequences of new gene emergence in plants.

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.

Abstract. Transitions from outcrossing to selfing and from diploidy to polyploidy often co-occur in plants, likely because the ability to produce selfed se
