Weighted ASTRID: fast and accurate species trees from weighted internode distances

open access: yesAlgorithms for Molecular Biology, 2023
Background Species tree estimation is a basic step in many biological research projects, but is complicated by the fact that gene trees can differ from the species tree due to processes such as incomplete lineage sorting (ILS), gene duplication and loss (

Discordance Between Mitochondrial and Nuclear Contact Zones Within Antelope Ground Squirrels (Ammospermophilus) [PDF]

open access: yes, 2020
A common biogeographic pattern found in many co-distributed species along the Baja California peninsula is the genetic divergence in the Vizcaíno Desert.

Three geographically separate domestications of Asian rice [PDF]

open access: yes, 2015
Domesticated rice (Oryza sativa L.) accompanied the dawn of Asian civilization(1) and has become one of world's staple crops. From archaeological and genetic evidence various contradictory scenarios for the origin of different varieties of cultivated ...

Red Blood Cells Internalize Extracellular DNA via Apoptotic Bodies with Clinical Relevance to Cancer Patients

open access: yesAdvanced Science, EarlyView.
Mature red blood cells (RBCs) can capture extracellular DNA, with short fragments homologous to cfDNA. This uptake is mediated by apoptotic bodies, which induce RBC oxidative stress, deformation, and accelerated in vivo clearance. The rbcDNA abundance correlates with tumor burden and therapeutic response, highlighting its potential as a liquid biopsy ...

Plasmodium vivax-like genome sequences shed new insights into Plasmodium vivax biology and evolution [PDF]

open access: yes, 2018
Although Plasmodium vivax is responsible for the majority of malaria infections outside Africa, little is known about its evolution and pathway to humans. Its closest genetic relative, P.

ETV1 Drives CD4+ T Cell‐Mediated Intestinal Inflammation in Inflammatory Bowel Disease Through Amino Acid Transporter Slc7a5

open access: yesAdvanced Science, EarlyView.
This study identifies the transcription factor ETV1 as a key driver of CD4⁺ T cell‐mediated intestinal inflammation in inflammatory bowel disease (IBD). ETV1 promotes CD4⁺ T cell activation, proliferation, and Th17 differentiation by activating the amino acid transporter SLC7A5, fueling metabolic reprogramming.

Fast Algorithms for Reconciliation under Hybridization and Incomplete Lineage Sorting

open access: yes, 2012
Reconciling a gene tree with a species tree is an important task that reveals much about the evolution of genes, genomes, and species, as well as about the molecular function of genes. A wide array of computational tools have been devised for this task under certain evolutionary events such as hybridization, gene duplication/loss, or incomplete lineage

Retroposon Insertion Patterns of Neoavian Birds: Strong Evidence for an Extensive Incomplete Lineage Sorting Era [PDF]

open access: yesMolecular Biology and Evolution, 2012
More than 150 Ma, the avian lineage separated from that of other dinosaurs and later diversified into the more than 10,000 species extant today. The early neoavian bird radiations most likely occurred in the late Cretaceous (more than 65 Ma) but left behind few if any molecular signals of their archaic evolutionary past.
