	Asparagales - Wikipedia, the free encyclopedia
		Asparagales is an order of monocots which includes a number of families of non-woody plants.
		In older classification systems, the families now included in the Asparagales were included in order Liliales, and some genera of which were even included in family Liliaceae.
		The Angiosperm Phylogeny Group's classification system is widely used by botanists, and was updated as the APG II in 2002 to include recent findings, especially in DNA analysis.

		To address further the higher-order relationships within Asparagales, we examined chloroplast sequence data from 15 families chosen to exemplify the phylogenetic diversity of the order (Agavaceae, Alliaceae, Amaryllidaceae, Anthericaceae, Aphyllanthaceae, Asparagaceae, Asphodelaceae, Boryaceae, Convallariaceae, Hyacinthaceae, Iridaceae, Laxmanniaceae, Orchidaceae, Phormiaceae and Tecophilaeaceae).
		Eight disjunct locations in the chloroplast genome were sequenced (spanning 17 chloroplast genes, three introns and three slowly evolving intergenic spacer regions), providing a total of 15 kb (unaligned) of DNA sequence data per taxon.
		The order’s monophyly was strongly upheld, as was its division into a lower Asparagales grade and a higher Asparagales clade, as indicated by Chase et al.

		The order Poales of the class Commelinanae possesses the most economically important monocots; the Asparagales is the second most economically valuable monocot order and includes such important plants as agave, aloe, asparagus, garlic, iris, onion, orchid, and vanilla.
		Genomic analyses of the Asparagales are hampered by relatively long generation times and some of the largest nuclear genomes known among all eukaryotes.
		Expressed sequence and genomic comparisons revealed strong differences between the Asparagales and Poales for mean GC content and distribution across coding regions, indicating that genomic characteristics are not uniform across the monocots.

	Asparagales
		As such, they are one of the most structurally diverse groups of monocots, ranging from small herbs to flowering Agaves that may reach more than ten meters in height.
		The plants shown are (clockwise, from upper left): Aloe saponaria growing in La Jolla, California; Amaryllis, a common ornamental; Dracaena draco, a sizeable tree on the Canary Islands; Triteilia, a relative of the onion; and Maianthemum dilatatum, an understory herb growing in northern California.
		Most members of the Asparagales produce a tight cluster of leaves at the base of the plant or on top of a squat trunk; from the top of this, a long stalk develops bearing the flowers.

		In particular, relationships are now fairly well established between the basal clades of the large monocot order Asparagales (the asparagoid lilies), based mainly on molecular data.
		Asparagales comprise a 'higher asparagoid' clade and a 'lower asparagoid' grade, which includes some small families such as Tecophilaeaceae, the monogeneric Eurasian family Ixioliriaceae, and the monotypic South African genus Lanaria (Lanariaceae), plus some large, cosmopolitan families such as Iridaceae and Orchidaceae, the latter putatively sister to all other Asparagales.
		A revised morphological cladistic analysis of Asparagales was undertaken to evaluate character support for these hypotheses of relationships and assess character evolution in Asparagales.

		Comparing instead a wide variety of genes both among the orchids and between orchids and the other flowering plants, Cameron and colleagues found that the orchids fell squarely within the so-called Asparagales, the group that includes asparagus.
		But the Asparagales is large and diverse, containing amaryllis, onions, irises, daffodils as well as agaves and yuccas.
		Now, when DNA data are used to build an evolutionary tree of the plants, they show that orchids branch off fairly early, the first among the Asparagales plants, meaning they are the oldest in that group.

		The Asparagales are a monophyletic order sister to the lineage carrying the Poales and possess economically important plants such as asparagus, garlic, and onion.
		Expressed sequence and genomic comparisons revealed strong differences between the Asparagales and Poales for codon usage and mean GC content, GC distribution, and relative GC content at each codon position, indicating that genomic characteristics are not uniform across the monocots.

	Asparagales
		Stem group Asparagales are dated to ca 122 mybp, crown group Asparagales to ca 119 mybp (Janssen and Bremer 2004), although Wikström et al.
		Rudall (2001a) included an inferior ovary as a synapomorphy of the order, noting that in "higher" Asparagales there may well be a reversal to superior ovaries that is associated with the presence of infralocular septal nectaries (as in Xanthorrhoea and Johnsonia (Hemerocallidaceae)).
		However, since superior ovaries are also scattered through the "lower" Asparagales, where the evolution of different ovary morphologies are to be placed in the tree is unclear; ovary position seems a much more flexible character here and elsewhere than it is generally given credit for being.

		But while DNA has provided these answers, Dr. Cameron said, researchers may have had clues to the history of the orchids if they had not focused so much on the showy and high profile orchid species.
		One curious aspect of the Asparagales is that their seeds are encased by a distinctive fl, crusty coat.
		Because most orchids have very thin seed coats, the Asparagales seemed unlikely to be close relatives.

	THE NEW PHYLOGENY OF THE LILIOID MONOCOTYLEDONS
		Much of this work was refined and placed into phylogenetic context by the late Rolf Dahlgren and coworkers.
		In Dahlgren, Clifford, and Yeo’s 1985 synthesis, the lilioid monocotyledons are recognized as two orders, the Asparagales, (31 families) and Liliales (10 families) that have evolved many traits in parallel.
		Two of the most important and consistent characters separating these two orders are the presence of septal nectaries in the ovary and phytomelan in the seed coat of Asparagales.

		Onion (Allium cepa) is the most economically important member of the monocot order Asparagales, followed by garlic (A. sativum), and asparagus (Asparagus officinalis).
		The Asparagales and Poales (contains the grass family) represent two distinct monophyletic groups in the monocots comprising the Lilianae and Commelinanae, respectively.
		A salient question is whether the genomic resources developed for rice or other members of the Poales will be applicable to the Asparagales.
