Furthermore, the poly - and paraphyly of several important families of core Caryophyllales demonstrate that
additional phylogenetic studies with increased taxon sampling are needed to resolve relationships and develop a truly phylogenetic classification.
«If we could understand better how these proteins with these
additional «integrated» domains were formed during recent evolution, then there is a good chance that we could engineer genes with specific domains to provide resistance to new types of pathogen attack,» says Paul Bailey, lead author of the
study who performed the
phylogenetic analysis.
