On Tree-Based Phylogenetic Networks [PDF]
Journal of Computational Biology, 2016 A large class of phylogenetic networks can be obtained from trees by the addition of horizontal edges between the tree edges. These networks are called tree based networks. Reticulation-visible networks and child-sibling networks are all tree based. In this work, we present a simply necessary and sufficient condition for tree-based networks and prove ...

Phylogenetic inference using Generative Adversarial Networks
Bioinformatics, 2022 AbstractMotivationThe application of machine learning approaches in phylogenetics has been impeded by the vast model space associated with inference. Supervised machine learning approaches require data from across this space to train models. Because of this, previous approaches have typically been limited to inferring relationships among unrooted ...

Advanced Sustainable Systems, EarlyView.Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

New Phytologist, 2020 While mutualistic interactions are widespread and essential in ecosystem functioning, the emergence of uncooperative cheaters threatens their stability, unless there are some physiological or ecological mechanisms limiting interactions with cheaters.

Improved Layout of Phylogenetic Networks [PDF]
IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2008 Split networks are increasingly being used in phylogenetic analysis. Usually, a simple equal angle algorithm is used to draw such networks, producing layouts that leave much room for improvement. Addressing the problem of producing better layouts of split networks, this paper presents an algorithm for maximizing the area covered by the network ...

Median-joining network analysis of SARS-CoV-2 genomes is neither phylogenetic nor evolutionary
Proceedings of the National Academy of Sciences of the United States of America, 2020 Tracking the spread of pandemics and the evolution of the underlying pathogens are effective tools for managing deadly outbreaks. Forster et al. (1) use a median-joining (MJ) network (MJN) and its Steinerization process to investigate the evolution of ...

Advanced Science, EarlyView.This study identifies elevated taurocholic acid (TCA) in Major Depressive Disorder patients. Gut microbiome‐associated TCA impairs hippocampal neurogenesis, triggers microglia activation, and elicits depression‐like behavior in mice via the S1PR2. In patients, functional neuroimaging reveals that serum TCA levels correlate with altered functional ...

Characterization of phylogenetic networks with NetTest [PDF]
BMC Bioinformatics, 2010 Typical evolutionary events like recombination, hybridization or gene transfer make necessary the use of phylogenetic networks to properly depict the evolution of DNA and protein sequences. Although several theoretical classes have been proposed to characterize these networks, they make stringent assumptions that will likely not be met by the ...
