ZOO-FISH mapping shows human chromosomes 1, 9 and 10 share regions of homology with pig chromosome 10 (SSC10). A more refined comparative map of SSC10 has been developed to help identify positional candidate genes for QTL on SSC10 from human genome sequence. Genes from relevant chromosomal regions of the public human genome sequence were used to BLAST porcine EST databases. Primers were designed from the matching porcine ESTs to assign them to porcine chromosomes using the INRA somatic cell hybrid panel (INRA-SCHP) and the INRA-University of Minnesota Radiation Hybrid Panel (IMpRH). Twenty-eight genes from HSA1, 9 and 10 were physically mapped: fifteen to SSC10 (ACO1, ATP5C1, BMI1, CYB5R1, DCTN3, DNAJA1, EPHX1, GALT, GDI2, HSPC177, OPRS1, NUDT2, PHYH, RGS2, VIM), eleven to SSC1 (ADFP, ALDHIB1, CLTA, CMG1, HARC, PLAA, STOML2, RRP40, TESK1, VCP and VLDLR) and two to SSC4 (ALDH9A1 and TNRC4). Two anonymous markers were also physically mapped to SSC10 (SWR1849 and S0070) to better connect the physical and linkage maps. These assignments have further refined the comparative map between SSC1, 4 and 10 and HSA1, 9 and 10.

It has recently been concluded that phylogenomic data from 310 nuclear genes support the clade of (Amborellales, Nymphaeales) as sister to the remaining angiosperms and that shortcut coalescent phylogenetic methods outperformed concatenation for these data. We falsify both of those conclusions here by demonstrating that discrepant results between the coalescent and concatenation analyses are primarily caused by the coalescent methods applied (MP-EST and STAR) not being robust to the highly divergent and often mis-rooted gene trees that were used. This result reinforces the expectation that low amounts of phylogenetic signal and methodological artifacts in gene-tree reconstruction can be more problematic for shortcut coalescent methods than is the assumption of a single hierarchy for all genes by concatenation methods when these approaches are applied to ancient divergences in empirical studies. We also demonstrate that a third coalescent method, ASTRAL, is more robust to mis-rooted gene trees than MP-EST or STAR, and that both Observed Variability (OV) and Tree Independent Generation of Evolutionary Rates (TIGER), which are two character subsampling procedures, are biased in favor of characters with highly asymmetrical distributions of character states when applied to this dataset. We conclude that enthusiastic application of novel tools is not a substitute for rigorous application of first principles, and that trending methods (e.g., shortcut coalescent methods applied to ancient divergences, tree-independent character subsampling), may be novel sources of previously under-appreciated, systematic errors.
