It is often suggested that horizontal gene transfer is so ubiquitous in microbes that the concept of a phylogenetic tree representing the pattern of vertical inheritance is oversimplified or even positively misleading. Here, we address this problem by proposing a visualization method and a statistical test within a Bayesian framework. We use the genomes of marine cyanobacteria, a group thought to exhibit substantial amounts of HGT, as a test case. We show that the tree space is strongly clustered and that the universal protein treecloud is statistically significantly closer congruence test dating the center of this tree space than any individual gene treecloud. The study of bacterial phylogenetics is complicated by the pervasive phenomenon of horizontal gene transfer HGTin which gene trees no longer reflect the vertical evolutionary history of cell division due to the incorporation of non-endogenous genes [1]. There is still contention regarding how frequently HGT occurs in nature. Marine cyanobacteria provide an intriguing case study of HGT, as it is thought that they have undergone a large amount of HGT [4]. The discovery that cyanophages contain laterally-acquired genes associated with the photosynthetic machinery of cyanobacteria provides an attractive mechanism for HGT mediated by phage transduction in marine environments [5]. Doolittle et al. Or can the tree of organismal congruence test dating, the tree derived from vertical inheritance of genes through standard cellular replication, still be estimated reliably, despite the horizontal transfer of some genes? However, it is generally accepted that vertical inheritance is vastly more frequent than horizontal transfer, at least if measured on a number-of-gene-replication-events-per-unit-time basis [1]. If this is true, then there is, in a meaningful sense, a tree of organismal relationships which is the product of these vertical replication events, whether or not it can accurately estimated. However, debate remains over significant issues. Alternatives to giving up on the search for the organismal tree exist. It has been hypothesized and observed that the Core Gene set is less likely to be laterally transferred in gamma-proteobacteria [8] ; thus, if Core Genes exist in the clade of interest, and can be reliably identified, they would provide a reasonable basis for estimating bacterial species trees. One option to assess the representativeness of a tree inferred from concatenation of a few well-conserved genes would be to attempt to detect HGT events in the rest of the genome. There are many different ways through which HGT can be identified, such as GC content, syntenic regions genomic islandsphylogenetic incongruence, and many others [10]. However, except for phylogenetic incongruence, the other hallmarks of HGT will usually be difficult to detect if the event is ancient, and thus most work on the estimation of the prevalence of HGT focuses on phylogenetic incongruence as the detection method. Phylogenetic incongruence is defined most simply as disagreement between trees — traditionally, the term is used to refer to disagreements in tree topology, but can also refer to disagreements in branch length. However, incongruence can be measured and represented in many different ways. Likelihood-based tests, such as the Shimodaira-Hasegawa SH test [11][12] and Approximate Unbiased AU test [13]are in common use in the literature, and provide a means to test the support of data for different tree hypotheses and infer incongruence between trees. Another method that has been employed in multiple studies is the quantification of conflict between genes by calculating congruent and conflicting topologies among quartets of taxa, and displaying the results with heat-maps [3][14]. A serious difficulty for any incongruence-based method is that there may be many sources of statistically significant phylogenetic incongruence, even in the hypothetical situation where absolutely no HGT has taken place. These include misestimation of the phylogenetic relationships of genes due to model-misspecification or misestimation, saturation of sequence divergence leading to insufficient phylogenetic signal, mistakes in sequence alignment, long-branch attraction, confusion of synapomorphies and plesiomorphies through mistaken rooting of the tree, and estimation errors due to missing taxa. Thus, even if statistically significant amounts of phylogenetic incongruence are observed, this does not congruence test dating that HGT is rampant; it is possible some other non-HGT factor explains some or all of the incongruence. In that hypothetical situation, non-HGT sources of noise are to blame for observed incongruence, and it might be defensible to attempt to compensate for this noise by, for example, concatenating a large number of genes so as to average out the noise.
