Detailed explanation-1: -Doug Soltis: Amborella represents the closest relative, or the what we call the basal member, of all flowering plants. So as such it means it really is a representative of some of the earliest flowering plants and it’s our best chance to reconstruct some of the features.
Detailed explanation-2: -Amborella has xylem tissue that differs from that of most other flowering plants. The xylem of Amborella contains only tracheids; vessel elements are absent. Xylem of this form has long been regarded as a primitive feature of flowering plants.
Detailed explanation-3: -The Amborella Genome Project (p. 10.1126/science. 1241089) was able to infer that a whole-genome duplication event preceded the evolution of this ancestral angiosperm, and Rice et al.
