Unmasking cryptic biodiversity in polyploids: origin and diversification of Aster amellus aggregate.

Summary of "Unmasking cryptic biodiversity in polyploids: origin and diversification of Aster amellus aggregate."

The origin of different cytotypes by autopolyploidy may be an important mechanism in plant diversification. Although cryptic autopolyploids probably comprise the largest fraction of overlooked plant diversity, our knowledge of their origin and evolution is still rather limited. Here we study the presumed autopolyploid aggregate of Aster amellus, which encompasses diploid and hexaploid cytotypes. Although the cytotypes of A. amellus are not morphologically distinguishable, previous studies showed spatial segregation and limited gene flow between them, which could result in different evolutionary trajectories for each cytotype.

Medical and Biotech [MESH] Definitions

A plant genus of the family ASTERACEAE. This plant should not be confused with microtubule asters (MICROTUBULES) nor with aster yellows phytoplasma (mycoplasma-like organisms).

The variety of all native living organisms and their various forms and interrelationships.

A large plant family of the order Asterales, subclass Asteridae, class Magnoliopsida. The family is also known as Compositae. Flower petals are joined near the base and stamens alternate with the corolla lobes. The common name of "daisy" refers to several genera of this family including Aster; CHRYSANTHEMUM; RUDBECKIA; TANACETUM.

The origin recognition complex is a multi-subunit DNA-binding protein that initiates DNA REPLICATION in eukaryotes.

A class of receptors that are activated by the action of PROTEINASES. The most notable examples are the THROMBIN RECEPTORS. The receptors contain cryptic ligands that are exposed upon the selective proteolysis of specific N-terminal cleavage sites.
