Introgression is a potential source of beneficial genetic diversity. The contribution of
introgression to adaptive evolution and improvement of wheat as it was disseminated …

The ciliate genus Paramecium served as one of the first model systems in microbial
eukaryotic genetics, contributing much to the early understanding of phenomena as diverse …

Whole-genome duplications (WGDs) have shaped the gene repertoire of many eukaryotic
lineages. The redundancy created by WGDs typically results in a phase of massive gene …

The hexaploid species Echinochloa crus-galli is one of the most detrimental weeds in crop
fields, especially in rice paddies. Its evolutionary history is similar to that of bread wheat …

According to the less-is-more hypothesis, gene loss is an engine for evolutionary change.
Loss-of-function (LoF) mutations resulting in the natural knockout of protein-coding genes …

Gene duplication is a key evolutionary phenomenon, prevalent in all organisms but
particularly so in plants, where whole genome duplication (WGD; polyploidy) is a major force …

Molecular evolution, including nucleotide substitutions, plays an important role in
understanding the dynamics and mechanisms of species evolution. Here, we sequenced …

The root-knot nematodes of the genus Meloidogyne are important and damaging parasites
capable of infecting most flowering plants. Within this genus, several species of the …
