Species boundaries and frequency of hybridization in the Dryopteris carthusiana (Dryopteridaceae) complex: A taxonomic puzzle resolved using genome size data.

Genome duplication and hybridization shape the characteristics, behavior, and reproduction patterns of land plants like the Dryopteris carthusiana complex. This group consists of one diploid species (D. expansa) and two allotetraploid species (D. carthusiana and D. dilatata) in Central Europe. Similar appearances, adaptability, and the presence of hybrids have created ongoing debates regarding species definitions. The study explores the significance of these processes in understanding the evolution and diversity of land plants.

Genome-specific SCAR markers help solve taxonomy issues: a case study with Sinapis arvensis (Brassiceae, Brassicaceae).

This study suggests that the current names and groupings of Brassiceae plants don't accurately depict their evolutionary history. Researchers believe it's necessary to revise the taxonomy and classification of these plants based on new molecular data to better understand their relationships. This conclusion comes from an analysis of several species within the Brassicaceae family. The findings provide important insight for researchers and could aid in future studies of these plants.
