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.

Understanding the mechanisms driving declines in biodiversity with latitude requires assessing if there are ecological limits to the number of species that can coexist, and if these limits vary with l...
We present the first plastome phylogeny encompassing all 77 monocot families, estimate branch support, and infer monocot-wide divergence times and rates of species diversification.
Advances in biodiversity science, coupled with new technologies and big data platforms, are expanding our ability to explore and understand the natural world. For the first time, biologists can link d...
Tropical mountains are disproportionately biodiverse relative to their surface area, but the processes underlying their exceptional diversity require further study. Here, we use comparative phylogenet...
Children will receive biodiversity intervention or placebo. The proof of concept trial is double blind. Intervention will start at the age of 2 months and last 10 months. Children will be ...
What is the role of Agricultural biodiversity in improving diet diversity, quality and nutrition?
This is the first study with a real diagnostic and prognostic focus in prenatal. In addition to this innovative aspect, the identification of cryptic imbalances in fetuses with malformativ...
Infrapyloric artery(IPA) is of great importance for gastric cancer patients. According to previous study, the origin of IPA varies greatly among different studies. This trial aims to tell ...
Fever of unknown origin (FUO) and biologic inflammatory syndrome of unknown origin (SII) are two frequent causes of hospitalization or consultation in infectious disease unit and internal ...
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.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
