Therefore, we performed a completely separate divergence-time analysis from a taxonomically more inclusive sample of six plastid gene regions (matK, ndhF, rbcL, trnL-F, rps16 and rpl16) available in GenBank (Additional file 6).
To address how many genes have cyanobacterial ancestry in plastid-lacking protists, and whether cyanobacterial ancestry is limited to this gnd gene or also found in other genes, we conducted a phylogenomic analysis using genome sequence data of a taxonomically wide range of plastid-lacking eukaryotes.
However, determining the exact mechanisms regarding the origin of lineage-specific genes depends on the comparative genome analysis of taxonomically closely related species.
A reliable and efficient alternative would be of immense value for many melissopalynological applications, especially those that require the analysis of large and taxonomically diverse pollen samples, such as are commonly collected by honey bees (Wilson et al., 2010).
Deciphering biological features of a taxonomically complex and ecologically dynamic microbial community is a challenging issue in gut microbiome research.
Nine novel examples of a taxonomically restricted family of potent cnidarian pore-forming toxins were also identified.
Analysis of FAD2 genes from taxonomically closely related plant species, such as those from the genus Centaurea within the Asteraceae family, could perhaps provide a better picture of exactly when the duplication events occurred.
Here we characterized the structure of Arabidopsis and rice GSK genes and conducted the first broad phylogenetic analysis of the plant GSK gene family, covering a taxonomically diverse array of algal and land plant sequences.
The status of such borderline organisms needs clarifying by a taxonomically broad and critical phylogenetic analysis of many conserved proteins and is potentially very important for understanding the origins of actinobacteria and neomura.
Using a taxonomically-stratified analysis of BLAST similarities, we identified more A. crassus TUGs that apparently arose in the common ancestor of Nematoda than arose in the last common ancestor of the Spirurina.
