The Magnoliaceae (/ m æ ɡ ˌ n oʊ l i ˈ eɪ s i i /) are a flowering plant family, the magnolia family, in the order Magnoliales. It consists of two genera: Magnolia and Liriodendron (tulip trees). Unlike most angiosperms, whose flower parts are in whorls (rings), the Magnoliaceae have their stamens and pistils in spirals on a conical ...
Magnoliids, Magnoliidae or Magnolianae are a clade of flowering plants.With more than 10,000 species, including magnolias, nutmeg, bay laurel, cinnamon, avocado, black pepper, tulip tree and many others, it is the third-largest group of angiosperms after the eudicots and monocots. [3]
In computational phylogenetics, tree alignment is a computational problem concerned with producing multiple sequence alignments, or alignments of three or more sequences of DNA, RNA, or protein. Sequences are arranged into a phylogenetic tree , modeling the evolutionary relationships between species or taxa .
Magnolia is a large genus of about 210 to 340 [a] flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae.The natural range of Magnolia species is disjunct, with a main center in east, south and southeast Asia and a secondary center in eastern North America, Central America, the West Indies, and some species in South America.
The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
Evolution of angiosperms shown in diagram format, per APG IV. The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG).
Tiger phylogenetic relationships, bootstrap values shown in branches. Example of long branch attraction. Longer branches (A & C) appear to be more closely related. There are many approaches to reconstructing phylogenetic trees, each with advantages and disadvantages, and there is no straightforward answer to “what is the best method?”.
Degeneriaceae (two species of trees found on Pacific islands) Eupomatiaceae (three species of trees and shrubs found in New Guinea and eastern Australia) Himantandraceae (two species of trees and shrubs, found in tropical areas in Southeast Asia and Australia) Magnoliaceae (about 225 species including magnolias and tulip trees)
