Comparison of gene arrangement data was also consistent with the phylogenetic relationships as inferred from sequence data.
a, All gene arrangement data are from Mitome http://www.mitome.info/ b, Proportion of taxa possessing one of the gene arrangements shown.
Here we present additional gene arrangement data, and compelling evidence for instances of gene gain by LGT, using phylogenetic analyses of the BR and HR functional types and comparison to the RNA polymerase B' subunit phylogeny (RpoB').
Along with a robust sister-group relationship in all phylogenetic analyses of amino acid sequences, gene arrangement data also provide the supporting evidence for the closer relationship between Cestoda and Trematoda.
There are some reports of lineage-specific idiosyncratic gene order patterns in metazoans including nematodes (e.g., enoplean nematodes [ 39], mollusks [ 44, 45], tunicates [ 46], crustacean arthropods [ 47]), and these cases illustrate that phylogenetic interpretation of gene arrangement data should be made with great caution.
The two complete mt genomes of caenogastropods sequenced so far and the incomplete mt genome of the caenogastropod L. saxatilis have identical gene arrangements (data not shown).
A potential translocation of ABC transporters between chromosomes 3 and 11 of potato (Sotub11g021420.1.1-Sotub11g021450.1.1 and Sotub03g024890.1.1-Sotub03g024920.1.1) may have occurred since the two chromosome segments show similar gene arrangements (data not shown).
Like 2L-1 and 3R-1, the frequency of gene arrangement XL (the sum of data for SS, S1, and S2), tends to be higher in southern populations than in northern ones [ 20].
According to this conserved gene arrangement in actinobacterial species and experimental data from mycobacteria, it is likely that OxyR controls at least the expression of the ahpCD genes in C. variabile DSM 44702.
The two genes are transcribed from different strands, both in the typical gene arrangement and in the inverted arrangement found in cecidomyiids.
