An HMM-based Comparative Genomic Framework for Detecting Introgression in Eukaryotes [PDF]
, 2013 One outcome of interspecific hybridization and subsequent effects of evolutionary forces is introgression, which is the integration of genetic material from one species into the genome of an individual in another species.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

PCR-activated cell sorting for cultivation-free enrichment and sequencing of rare microbes.
PLoS ONE, 2015 Microbial systems often exhibit staggering diversity, making the study of rare, interesting species challenging. For example, metagenomic analyses of mixed-cell populations are often dominated by the sequences of the most abundant organisms, while those ...

Reticulate evolutionary history of a complex group of grasses: phylogeny of Elymus StStHH allotetraploids based on three nuclear genes. [PDF]
PLoS ONE, 2010 BACKGROUND: Elymus (Poaceae) is a large genus of polyploid species in the wheat tribe Triticeae. It is polyphyletic, exhibiting many distinct allopolyploid genome combinations, and its history might be further complicated by introgression and lineage ...

Species Tree Branch Length Estimation despite Incomplete Lineage Sorting, Duplication, and Loss. [PDF]
Genome Biol EvolAbstract Phylogenetic branch lengths are essential for many analyses, such as estimating divergence times, analyzing rate changes, and studying adaptation. However, true gene tree heterogeneity due to incomplete lineage sorting, gene duplication and loss, and horizontal gene transfer can complicate the estimation of species tree ...

A polynomial time algorithm for calculating the probability of a ranked gene tree given a species tree [PDF]
, 2012 In this paper, we provide a polynomial time algorithm to calculate the probability of a {\it ranked} gene tree topology for a given species tree, where a ranked tree topology is a tree topology with the internal vertices being ordered. The probability of

Ultramafic soils and species sorting in the flora of New Caledonia [PDF]
Journal of Ecology, 2010 Summary1. Island floras are generally characterized by disharmony due to uneven representations of plant groups. This has usually been explained by the unequal capacity of plants to disperse and colonize islands, but it has been suggested that the ecology of the recipient islands may also be important.2.

Molecular Oncology, EarlyView.This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

Molecular Oncology, EarlyView.Urinary LGALS3BP is elevated in bladder cancer patients compared to healthy controls as detected by the 1959 antibody–based ELISA. The antibody shows enhanced reactivity to the high‐mannose glycosylated variant secreted by cancer cells treated with kifunensine (KIF).
