Unraveling the evolutionary dynamics of ancient and recent polypoidization events in Avena (Poaceae)
Understanding the diversification of polyploid crops in the circum-Mediterranean region is a challenging issue in evolutionary biology. Sequence data of three nuclear genes and three plastid DNA fragments from 109 accessions of Avena L. (Poaceae) and the outgroups were used for maximum likelihood and Bayesian analyses. The evolution of cultivated oat (Avena sativa L.) and its close relatives wa...
متن کاملAncient polyploidization predating divergence of the cereals, and its consequences for comparative genomics.
Integration of structural genomic data from a largely assembled rice genome sequence, with phylogenetic analysis of sequence samples for many other taxa, suggests that a polyploidization event occurred approximately 70 million years ago, before the divergence of the major cereals from one another but after the divergence of the Poales from the Liliales and Zingiberales. Ancient polyploidization...
متن کاملA Phylogenomic Assessment of Ancient Polyploidy and Genome Evolution across the Poales
Comparisons of flowering plant genomes reveal multiple rounds of ancient polyploidy characterized by large intragenomic syntenic blocks. Three such whole-genome duplication (WGD) events, designated as rho (ρ), sigma (σ), and tau (τ), have been identified in the genomes of cereal grasses. Precise dating of these WGD events is necessary to investigate how they have influenced diversification rate...

In this paper we have tried mention to some sort of thewell-known evolutionary modeling approaches in economic territory such as Multi Agent simulations, Evolutionary Computation and Evolutionary Game Theory. As it has been mentioned in the paper, in recent years, the number of Evolutionary contributions applied to Multi-Agent models increased remarkably. However until now there is no consensus...
متن کاملUnraveling ancient segmental duplication events in human genome by phylogenetic analysis of multigene families residing on HOX-cluster paralogons.
BACKGROUND Vertebrate genomes contain extensive intra-genomic conserved synteny, which is the presence of similar set of genes on two or more chromosomes (paralogons). The existence of these paralogons has led to the proposal that vertebrate genome was structured by one or more rounds of ancient whole genome duplications (2R hypothesis). RESULTS The 2R hypothesis was tested by phylogenetic an...
