Research Assistant/Associate in Genomic Microbiology at Imperial College London This position has become available within the MRC Centre for Outbreak Analysis and Modelling at Imperial College London. The MRC Centre has built upon a world-leading research group in the Department of Infectious Disease Epidemiology at Imperial College London to undertake applied collaborative work with national and international agencies in support of policy planning for emerging and endemic infectious diseases. The successful candidate will be a member of both the Centre and the Department, and will be based at the St Mary’s Campus, Paddington. The purpose of this post is to develop statistical and computational methods to perform genome-wide association mapping in bacteria. Important biomedical properties often vary within a bacterial species, for example antibiotic resistance, virulence, host-specificity or tissue-specificity. The genetic basis for these variations is not often fully understood by microbiologists, but this question can be approached computationally by comparing the genome sequences of bacteria with different properties. Working closely with Dr Xavier Didelot, the post-holder will develop the methodology required to perform such analysis and create a new software tool which will be applicable by microbial researchers around the world. To be valid, the new methods will need to account for the specificity of bacterial evolutionary process, especially in terms of recombination, genetic content and population structure. Thorough testing of the software will be performed using simulated datasets, as well as real existing collections of several hundreds of genomes of two major enteric pathogens, Escherichia coli and Campylobacter jejuni. The successful applicant must have an MSc (for appointment to Research Assistant) or a PhD (for appointment to Research Associate) or equivalent in one of the following areas: mathematics, statistics, computer science, infectious disease epidemiology or population biology. They will also have research experience of programming in at least one high level language and experience of working with genetic sequence data. The post is full time for a fixed term from 1st September 2014 to 31st August 2016. For informal enquiries please contact Dr Xavier Didelot (firstname.lastname@example.org).

Andreas Wagner has a new paper on analyzing influenza sequence data using a super simple Hamming-distance network-based approach.
www.ncbi.nlm.nih.gov A genotype network reveals homoplastic cycles of convergent evolution in influenza A (H3N2) haemagglutinin. A Wagner, Proceedings. Biological sciences / The Royal Society, Jul 7 2014
Networks of evolving genotypes can be constructed from the worldwide time-resolved genotyping of pathogens like influenza viruses. Such genotype networks are graphs where neighbouring vertices (viral strains) differ in a single nucleotide or amino acid. A rich trove of network analysis methods can help understand the evolutionary dynamics reflected in the structure of these networks. Here, I analyse a genotype network comprising hundreds of influenza A (H3N2) haemagglutinin genes. The network is rife with cycles that reflect non-random parallel or convergent (homoplastic) evolution. These cycles also show patterns of sequence change characteristic for strong and local evolutionary constraints, positive selection and mutation-limited evolution. Such cycles would not be visible on a phylogenetic tree, illustrating that genotype network analysis can complement phylogenetic analyses. The network also shows a distinct modular or community structure that reflects temporal more than spatial proximity of viral strains, where lowly connected bridge strains connect different modules. These and other organizational patterns illustrate that genotype networks can help us study evolution in action at an unprecedented level of resolution.
He ends up with plots like:
Fundamentally non-phylogenetic, this approach doesn't try to reconstruct evolutionary history, but instead shows a simple overview of genetic relationships. Andreas suggests that these graphs make it easy to detect convergent evolution that would not be apparent in the strictly branching tree.
I don't have a good intuition for how these sorts of graphs translate to trees and vice versa. Does this seem like it's a useful addition to constructing a tree or more of a distraction?

July 2, 2014
Background: To understand the processes that generate biodiversity, it is important to account for large-scale processes that affect the evolutionary history of groups of co-distributed populations of organisms. Such events predict temporally clustered divergences times, a pattern that can be estimated using genetic data from co-distributed species. I introduce a new approximate-Bayesian method for comparative phylogeographical model-choice that estimates the temporal distribution of divergences across taxa from multi-locus DNA sequence data. The model is an extension of that implemented in msBayes. Results: By reparameterizing the model, introducing more flexible priors on demographic and divergence-time parameters, and implementing a non-parametric Dirichlet-process prior over divergence models, I improved the robustness, accuracy, and power of the method for estimating shared evolutionary history across taxa. Conclusions: The results demonstrate the improved performance of the new method is due to (1) more appropriate priors on divergence-time and demographic parameters that avoid prohibitively small marginal likelihoods for models with more divergence events, and (2) the Dirichlet-process providing a flexible prior on divergence histories that does not strongly disfavor models with intermediate numbers of divergence events. The new method yields more robust estimates of posterior uncertainty, and thus greatly reduces the tendency of the model to incorrectly estimate models of shared evolutionary history with strong support.

Background: The relationship between allopolyploidy and plant virus resistance is poorly understood. To determine the relationship of plant evolutionary history and basal virus resistance, a panel of Nicotiana species from diverse geographic regions and ploidy levels was assessed for resistance to non-coevolved viruses from the genus Nepovirus, family Secoviridae. The heritability of resistance was tested in a panel of synthetic allopolyploids. Leaves of different positions on each inoculated plant were tested for virus presence and a subset of plants was re-inoculated and assessed for systemic recovery. Results: Depending on the host-virus combination, plants displayed immunity, susceptibility or intermediate levels of resistance. Synthetic allopolyploids showed an incompletely dominant resistance phenotype and manifested systemic recovery. Plant ploidy was weakly negatively correlated with virus resistance in Nicotiana species, but this trend did not hold when synthetic allopolyploids were taken into account. Furthermore, a relationship between resistance and geographical origin was observed. Conclusion: The gradients of resistance and virulence corresponded to a modified matching allele model of resistance. Intermediate resistance responses of allopolyploids corresponded with a model of multi-allelic additive resistance. The variable virus resistance of extant allopolyploids suggested that selection-based mechanisms surpass ploidy with respect to evolution of basal resistance to viruses.

I recently wrote a manuscript comparing the tree-likeness of phylogenetic data in biology and anthropology (see Are phylogenetic patterns the same in anthropology and biology?). While doing so, I also made a comparison of genotype and phenotype data within biology.
The comparison is based on maximum-parsimony analyses of the data, using the (ensemble) Retention Index (RI) as the measure of tree-likeness. If RI = 1 then all of the characters are compatible with the same tree, whereas if RI = 0 then none of them are pairwise compatible. As the graph shows, the genotype data are considerably less tree-like than are the phenotype data (mean RI ≈ 0.5 versus 0.7, respectively).
It would be interesting to know whether other people have observed this pattern. If it is general, then what causes it? Are the phenotype characters being chosen (subconsciously or not) because they show nested grouping patterns (which lend themselves automatically to a tree representation)? Or do the genotype data inherently have more stochastic variation? Does this mean that we should always be using phylogenetic networks for the representation of genotype data?
You can read the manuscript if you want the details of the analyses. Briefly, the initial collections of datasets were taken from Collard et al. (Evolution and Human Behavior 27: 169-184; 2006) — the graphed data are taken from the paper as I never managed to get the original datasets from the authors. I then supplemented this information with phenotype datasets from TreeBase (total of n=31) and miscellaneous genotype datasets from the literature (n=15). All of the datasets refer to vertebrates and insects (with one phenotype dataset from spiders). My parsimony analyses used the parsimony ratchet and PAUP*.
