Gene duplication is an important evolutionary mechanism allowing to provide new genetic
material and thus opportunities to acquire new gene functions for an organism, with major …

Heterosis, also known as hybrid vigor, is the phenomenon wherein a progeny exhibits
superior traits relative to one or both parents. In terms of crop breeding, this usually refers to …

Evolutionary variations generating phenotypic adaptations and novel taxa resulted from
complex cellular activities altering genome content and expression:(i) Symbiogenetic cell …

In Drosophila melanogaster, there is an excess of genes duplicated by retroposition from the
X chromosome to the autosomes. Most of those retrogenes that originated on the X …

CFEM domain commonly occurs in fungal extracellular membrane proteins. To provide
insights for understanding putative functions of CFEM, we investigate the evolutionary …

Background Protein domains are protein regions that are shared among different proteins
and are frequently functionally and structurally independent from the rest of the protein …

Grain number is an important factor in determining grain production of rice (Oryza sativa L.).
The molecular genetic basis for grain number is complex. Discovering new genes involved …

Tandem gene duplication is one of the major gene duplication mechanisms in eukaryotes,
as illustrated by the prevalence of gene family clusters. Tandem duplicated paralogs usually …

The evolution of keratins was closely linked to the evolution of epithelia and epithelial
appendages such as hair. The characterization of keratins in model species and recent …

Transposable elements (TEs) are able to jump to new locations (transposition) in the
genome, usually after replication. They constitute the so-called selfish or junk DNA and take …
