Bridging the gap between rooted and unrooted phylogenetic networks [PDF]

open access: yesarXiv, 2015
The need for structures capable of accommodating complex evolutionary signals such as those found in, for example, wheat has fueled research into phylogenetic networks. Such structures generalize the standard phylogenetic tree model by also allowing cycles and have been introduced in rooted and unrooted form. In contrast to phylogenetic trees, however,

Multiple Comparisons of Log-Likelihoods with Applications to Phylogenetic Inference

open access: yesMolecular biology and evolution, 1999
The maximum-likelihood method for inferring mo-lecular phylogeny (Felsenstein 1981) is being widelyused. The probabilistic model for generating the molec-ular sequences is specified by the substitution processand the tree topology.

DDX3 Regulates the Cap‐Independent Translation of the Japanese Encephalitis Virus via Its Interactions with PABP1 and the Untranslated Regions of the Viral Genome

open access: yesAdvanced Science, EarlyView.
Japanese encephalitis virus (JEV) employs a cap‐independent (CI) translation strategy to evade host translational shutoff. During the shut‐off of host cellular canonical translation, DEAD‐box protein 3 (DDX3) bind to JEV UTRs to establish a closed‐loop architecture, and its interaction with poly(A)‐binding protein 1 (PABP1) to form DDX3/PABP1/eIF4G ...

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

open access: yesAdvanced Science, EarlyView.
Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

deepTFBS: Improving within‐ and Cross‐Species Prediction of Transcription Factor Binding Using Deep Multi‐Task and Transfer Learning

open access: yesAdvanced Science, EarlyView.
DeepTFBS leverages deep learning to predict transcription factor binding sites across species, integrating multi‐task and transfer learning approaches to improve performance in data‐scarce scenarios. This study demonstrates enhanced accuracy in intra‐ and cross‐species prediction, revealing conserved regulatory patterns and functional variants.

Syntactic Phylogenetic Trees [PDF]

open access: yesarXiv, 2016
In this paper we identify several serious problems that arise in the use of syntactic data from the SSWL database for the purpose of computational phylogenetic reconstruction. We show that the most naive approach fails to produce reliable linguistic phylogenetic trees. We identify some of the sources of the observed problems and we discuss how they may

Molecular phylogenetics of Gobioidei and phylogenetic placement of European gobies

open access: yesMolecular Phylogenetics and Evolution, 2013
Gobioidei is one of the largest suborders of teleost fishes, with nearly 2000 extant species currently recognized. They have a worldwide distribution and show a spectacular variety in morphology, ecology, and behavior. Despite their importance, phylogenetic relationships among many groups of gobioids (including some of the major lineages) still remain ...

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle

open access: yesAdvanced Science, EarlyView.
This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

Magnetite Micro/Nanorobots for Efficient Targeted Alleviation of Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
Improved reactive oxygen species scavenging capacities of functionalized micro/nanorobots (MNRs) are useful for the treatment of inflammatory bowel disease (IBD). MNRs can break the harmful bacteria in IBD, thereby eliminating inflammation and restoring the intestinal barrier function.

Variation and development of the turtle chondrocranium, with a description of the common musk turtle (Sternotherus odoratus, Kinosternidae, Cryptodira, Testudines)

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...
