sphaeroides protein in each duplicate protein-pair,

Cisplatin order the tree type (Type-A or Type-B) for the protein-pair, and the bootstrap values for each tree. Of the total 234 protein-pairs, ~77% of the protein-pairs (180 pairs) exhibited a Type-A relationship and ~23% of the protein-pairs (54 pairs) showed a Type-B relationship. Figure 6 The phylogenetic relationship of duplicate protein pairs and their highest matching ortholog sequences. Maximum likelihood trees representing four of these relationships are shown above for hisD I and hisD II , sdhB and frdB, sac1 and a hypothetical protein, and traI and a hypothetical protein. Each of these unrooted trees displayed a bootstrap value of 100. The offshoots represent branches and their lengths are given (trees are not to scale). The relationships depict two types of topology – Type A or Type B. The strength of the tree topology was analyzed using bootstrap

values, information concerning which is also shown in Acalabrutinib price Additional file 2. Bootstrap values for 8 trees could not be determined due to the lack of one or more orthologs. Lazertinib Bootstrap values not only signify the significance of a tree topology (Type-A and Type-B), but also provide an insight into the relative origin of a given gene duplication. Gene duplication events that occurred significantly before organism speciation would display Type-A relationships with high bootstrap values. Gene duplication events that occurred significantly after organism speciation would display Type-B relationships with similarly high bootstrap values. Of the 226 trees for which bootstrap values were obtained, 209 (92.5%) Diflunisal had bootstrap values ≥ 95. The bootstrap values remained significant within both Type-A and Type-B phylogenetic trees.

Of the 180 Type-A trees, 172 (95.56%) exhibited ≥ 95 bootstrap values while of the 46 Type-B trees, 37 (80.43%) exhibited ≥ 95 bootstrap values. Thus, the majority of these trees demonstrated correct and significant trees topologies, which support the relative timings of the origins of these gene duplications. These results clearly show that a majority of gene duplications in R. sphaeroides originated prior to the formation of the R. sphaeroides lineage as also shown in Table 1. Of the Type-A gene duplications, 58.33% (105 pairs) were found only on CI, 26.67% (48 pairs) were found between CI and CII, and 6.11% (11 pairs) were found only on CII. Since about 91% of the duplications exhibiting a Type-A relationship were distributed on the two chromosomes, these results submit that the origin of multiple chromosomes in R. sphaeroides predates the origin of this species. 13 proteins had indiscernible matches to any orthologs in the current microbial database. Moreover, although a vast majority of the genes (312 of 360 genes, 86.
