Example sentences for: phylogeny

How can you use “phylogeny” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Runt domain sequences across phylogeny

  • HGT of arsC from an ancestral low GC Gram-positive bacterium to an ancestral cyanobacterium seems likely, and a similar HGT event from ancestral Actinobacteria to the Streptococci would explain the unexpected phylogeny of the Streptococcus arsC sequences.

  • This is a both an advantage and a disadvantage over analyses that rely on phylogeny.

  • Specifically, for each protein phylogeny, the length of the longest branch was compared to the sum of the two shorter branches (Figure 1).

  • The most straightforward version of this type of analysis, to which we hereinafter refer to as 'genome-tree' building, involves scaling-up the traditional tree-building approach and analyzing the phylogenetic trees for multiple gene families (in principle, all families represented in many genomes), in an attempt to derive a consensus, 'organismal' phylogeny [ 3 4 5 ] . However, because of the wide spread of horizontal gene transfer and lineage-specific gene loss, at least in the prokaryotic world, comparison of trees for different families and consensus derivation may become highly problematic [ 6 7 ] . Probably due to all these problems, a pessimistic conclusion has been reached that prokaryotic phylogeny might not be reconstructable from protein sequences, at least with current phylogenetic methods [ 4 ] .
