GLaMST: grow lineages along minimum spanning tree for b cell receptor sequencing data

open access: yesBMC Genomics, 2020
Background B cell affinity maturation enables B cells to generate high-affinity antibodies. This process involves somatic hypermutation of B cell immunoglobulin receptor (BCR) genes and selection by their ability to bind antigens.

Potential vector switching in the evolution of Bursaphelenchus xylophilus group nematodes (Nematoda: Aphelenchoididae)

open access: yesEcology and Evolution, 2020
To show the importance of vector switching of nematodes in the evolution of the Bursaphelenchus xylophilus group, we tested a hypothesis that “Bursaphelenchus doui (or its ancestor) was transferred by Acalolepta fraudatrix, Acalolepta sejuncta, and/or ...

A combination theorem for affine tree-free groups [PDF]

open access: yesInternational Journal of Algebra and Computation, 2016
Let [Formula: see text] be an ordered abelian group. We show how a group admitting a free affine action without inversions on a [Formula: see text]-tree admits a natural graph of groups decomposition, where vertex groups inherit actions on [Formula: see text]-trees.

Bacterial Metabolites Produced Under Iron Limitation Kill Pinewood Nematode and Attract Caenorhabditis elegans

open access: yesFrontiers in Microbiology, 2019
Pine Wilt Disease (PWD) is caused by Bursaphelenchus xylophilus, the pinewood nematode, and affects several species of pine trees worldwide. The ecosystem of the Pinus pinaster trees was investigated as a source of bacteria producing metabolites ...

Phytogeographical Affinities of Tree Species of Similipal Biosphere Reserve, Odisha, India

open access: yesNotulae Scientia Biologicae, 2018
The phytogeography of Similipal Biosphere Reserve (SBR), Odisha, India, reveals very interesting information on distribution of tree species.  Phytogeographical affinities of tree species of SBR has been analysed by obtaining the information about the ...

Deep geometric representations for modeling effects of mutations on protein-protein binding affinity.

open access: yesPLoS Computational Biology, 2021
Modeling the impact of amino acid mutations on protein-protein interaction plays a crucial role in protein engineering and drug design. In this study, we develop GeoPPI, a novel structure-based deep-learning framework to predict the change of binding ...

Predicting MHC-peptide binding affinity by differential boundary tree

open access: yesBioinformatics, 2021
Abstract Motivation The prediction of the binding between peptides and major histocompatibility complex (MHC) molecules plays an important role in neoantigen identification. Although a large number of computational methods have been developed to address this problem, they produce high false-positive ...

Conifer wood assemblage dominated by Podocarpaceae, early Eocene of Laguna del Hunco, central Argentinean Patagonia [PDF]

open access: yesPhytoKeys, 2020
During the early Eocene, Patagonia had highly diverse floras that are primarily known from compression and pollen fossils. Fossil wood studies from this epoch are scarce in the region and largely absent from the Laguna del Hunco flora, which has a highly

Evaluation of selected nursery traits in combination rootstocks and variety for Asian pear trees

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
Evaluation of the nursery traits of rootstocks and varieties is an important tool for optimisation of the fruit orchard plants final growing. The present experiment evaluated the standard and progressive rootstocks for the pear trees in combination with ...
