Shifts in diversification rates and host jump frequencies shaped the diversity of host range among Sclerotiniaceae fungal plant pathogens

Olivier Navaud, Adelin Barbacci, Andrew Taylor, John P. Clarkson, Sylvain Raffaele
2018 Molecular Ecology  
Mathematical analyses and studies of the host range of insect herbivores suggest that host range expansion could involve the emergence of a "pre-adaptation" followed by the colonization of new hosts (  ...  First, we used a neighbour-joining approach in FastME 2.0 (Lefort, Desper, & Gascuel, 2015) with the LogDet substitution model and tree refinement by subtree pruning and regrafting (File S5).  ...

Shifts in diversification rates and host jump frequencies shaped the diversity of host range amongSclerotiniaceaefungal plant pathogens [article]

Olivier Navaud, Adelin Barbacci, Andrew Taylor, John P Clarkson, Sylvain Raffaele
2017 bioRxiv   pre-print
The range of hosts that a parasite can infect in nature is a trait determined by its own evolutionary history and that of its potential hosts.  ...  These results have important implications for our understanding of fungal parasites evolution and are of particular relevance for the durable management of disease epidemics.  ...  Molecular phylogeny and evolution of Monilinia (Sclerotiniaceae) 570 based on coding and noncoding rDNA sequences.  ...

Do plants have a segregated germline?

Robert Lanfear
2018 PLoS Biology  
Answering these questions is vital to understanding one of the most fundamental aspects of plant development and evolution.  ...  How can we reconcile the new evidence with existing knowledge of plant development? And is there a way to reliably establish the timing of germline segregation in both model and nonmodel plants?  ...  Acknowledgments I would like to thank Eleanor Beavan, Lindell Bromham, Olivier Gascuel, and Alejandro Morales-Suarez for extensive and lively discussions on this topic.  ...

Comparing Timeline Rhythms in Pygmy and Bushmen Music

Adrian Poole
2018 Empirical Musicology Review  
The findings suggest that Pygmy and Bushmen timelines are interrelated and that most are organised according to the principles of 'rhythmic oddity' and maximal evenness.  ...  Combining theories of African rhythm from ethno/musicology and findings from anthropological research and population genetics with musical analyses based on transcriptions and computational phylogenetic  ...  node (Gascuel, 1997) .  ...

Barking Up The Wrong Treelength: The Impact of Gap Penalty on Alignment and Tree Accuracy

K. Liu, S. Nelesen, S. Raghavan, C.R. Linder, T. Warnow
2009 IEEE/ACM Transactions on Computational Biology & Bioinformatics  
Since this optimization depends upon the specific edit distance criterion used to score a tree, our study considers the impact of the gap penalty (in particular, affine versus simple) on the accuracy of  ...  The current technique for estimating phylogenies from sequence data uses two phases: first, the sequences are aligned, and then the tree is estimated using the obtained alignment.  ...  This work was supported by the Sir Isaac Newton Institute for Mathematical Sciences, and by the US National Science Foundation under Grants DEB-07330209, ITR-0331453, ITR-0121680, ITR-0114387, and EIA-  ...

Review Paper: The Shape of Phylogenetic Treespace

St. John Katherine
2016 Systematic Biology  
The underlying structure of the spaces of trees yields rich insights that can improve the search for optimal trees, both in accuracy and in running time, and the analysis and visualization of results.  ...  We review the past work on analyzing and comparing trees by their shape as well as recent work that incorporates trees with weighted branch lengths.  ...  ACKNOWLEDGMENTS The author would like to thank the organizing committee of the Mathematical and Computational Evolutionary Biology 2015 conference, to Olivier Gascuel and David Bryant for inviting this  ...

A Fast Likelihood Method to Reconstruct and Visualize Ancestral Scenarios [article]

Sota Ishikawa, Anna Zhukova, Wataru Iwasaki, Olivier Gascuel
2018 bioRxiv   pre-print
The reconstruction of ancestral scenarios is widely used to study the evolution of characters along a phylogenetic tree.  ...  The results on simulated data consistently show the accuracy and robustness of the approach.  ...  Simulations performed by Gascuel and Steel (2014) showed that the predictions and accuracy of both are extremely close.  ...

Divisions asymétriques ovocytaires / Asymmetric divisions in oocytes

Marie-Hélène Verlhac
2020 Annuaire du Collège de France : Résumé Des Cours et Travaux  
Indeed, innervation of peripheral resistance arteries by autonomic sympathetic nerves controls response to stress and blood supply to organs by regulating vascular tone (Storkebaum E. et al., 2011).  ...  Netrin-1 is produced by SMCs at the onset of innervation and signals via its receptor deleted in colorectal cancer (DCC) to attract sympathetic growth cones.  ...  Dynamics is limited in this case first by the slow regulation of surface tensions, and morphogenesis is well captured by a quasi-static mechanical description, as we recently proposed for compaction and  ...
