Defense islands in bacterial and archaeal genomes and prediction of novel defense systems

KS Makarova, YI Wolf, S Snir, EV Koonin - Journal of bacteriology, 2011 - Am Soc Microbiol
The arms race between cellular life forms and viruses is a major driving force of evolution. A
substantial fraction of bacterial and archaeal genomes is dedicated to antivirus defense. We …

Maximum likelihood of phylogenetic networks

G Jin, L Nakhleh, S Snir, T Tuller - Bioinformatics, 2006 - academic.oup.com
Motivation: Horizontal gene transfer (HGT) is believed to be ubiquitous among bacteria, and
plays a major role in their genome diversification as well as their ability to develop …

Quartets MaxCut: a divide and conquer quartets algorithm

S Snir, S Rao - IEEE/ACM Transactions on Computational …, 2008 - ieeexplore.ieee.org
Accurate phylogenetic reconstruction methods are currently limited to a maximum of few
dozens of taxa. Supertree methods construct a large tree over a large set of taxa, from a set of …

C Farrell, S Snir, M Pellegrini - Bioinformatics, 2020 - academic.oup.com
… The authors wish it to be known that, in their opinion, Sagi Snir and Matteo Pellegrini should
… The authors wish it to be known that, in their opinion, Sagi Snir and Matteo Pellegrini should …

Quartet MaxCut: a fast algorithm for amalgamating quartet trees

S Snir, S Rao - Molecular phylogenetics and evolution, 2012 - Elsevier
Accurate phylogenetic reconstruction methods are inherently computationally heavy and
therefore are limited to relatively small numbers of taxa. Supertree construction is the task of …

[HTML][HTML] Hibernation slows epigenetic ageing in yellow-bellied marmots

…, A Haghani, JA Zoller, J Zhang, S Snir… - Nature ecology & …, 2022 - nature.com
Species that hibernate generally live longer than would be expected based solely on their
body size. Hibernation is characterized by long periods of metabolic suppression (torpor) …

Weighted quartets phylogenetics

E Avni, R Cohen, S Snir - Systematic biology, 2015 - academic.oup.com
Despite impressive technical and theoretical developments, reconstruction of phylogenetic
trees for enormous quantities of molecular data is still a challenging task. A key tool in …

Human epigenetic ageing is logarithmic with time across the entire lifespan

S Snir, C Farrell, M Pellegrini - Epigenetics, 2019 - Taylor & Francis
Epigenetic changes during ageing have been characterized by multiple epigenetic clocks
that allow the prediction of chronological age based on methylation status. Despite their …

[HTML][HTML] Detecting horizontal gene transfer between closely related taxa

O Adato, N Ninyo, U Gophna, S Snir - PLoS computational biology, 2015 - journals.plos.org
Horizontal gene transfer (HGT), the transfer of genetic material between organisms, is crucial
for genetic innovation and the evolution of genome architecture. Existing HGT detection …

Inferring phylogenetic networks by the maximum parsimony criterion: a case study

G Jin, L Nakhleh, S Snir, T Tuller - Molecular Biology and …, 2007 - academic.oup.com
Horizontal gene transfer (HGT) may result in genes whose evolutionary histories disagree
with each other, as well as with the species tree. In this case, reconciling the species and …
