The program searches for defined k-mers (motives), one from each sequence, within the set of sequences allowing for nucleotide substitutions within the k-mers depending on the phylogenetic relation, i.e. more closely related species are expected to share more similarity.
Nicotone is such a distant cousin of nicotine that the only phylogenetic relation is that one of these plants once grew, it's said, in the same field where some teen-agers used to hang out and smoke between classes.
Considering the close phylogenetic relation of certain fungi to humans, fungi could serve as excellent model systems to study the roles of carotenoids in health and aging.
The functional analysis revealed multiple transmembrane regions in GPI 14 and a close phylogenetic relation with Trypanosoma species and Schistosoma mansoni with highest bootstrap values.
The outcome of phylogenetic relation based on molecular analysis between different or similar populations of Pleurotus species provides a better resolution and understanding of their biogeography and speciation [5].
However, data from the species with the closest phylogenetic relation to humans, chimpanzees, are relatively scarce.
An enzyme with a similar tetrameric arrangement and a close phylogenetic relation with HpPgdA is PuuE allantoinase, whose natural substrate is in fact a small cyclic imide.
The classification of the myosins is based on the phylogenetic relation of the myosin motor domains.
