  Poales - Wikipedia, the free encyclopedia
Poales is a botanical name at the rank of order.
The Cronquist system did not recognize an order named Poales: the plants as included by APG II were assigned to the orders Bromeliales, Cyperales, Hydatellales, Juncales, Restionales and Typhales.

The Poales basically corresponds to the Order Restionales in Cronquist's (1981) classification, except that he placed the grasses in the Order Cyperales.

 Poales
The Poales are an order of monocot flowering plants, including the grasses and their relatives.
This group basically corresponds to the order Restionales in Cronquist's classification, except that he placed the grass family itself (the Poaceae) in a different order, the Cyperales.
By far, the most economically important family is the Poaceae, the grass or corn family, including barley, maize, millet, rice, and wheat.

 Poales
The general pattern of movement of genes from the mitochondrion to the nucleus is interesting; it suggests that Bromeliaceae and Typhaceae (of the taxa sampled) are sister to other Poales (Adams and Palmer 2003), and of course Bromeliaceae have septal nectaries, alone in the clade.
Within Poales there are some well-supported groups, the Xyridaceae, Juncaceae and Poaceae and their respective relatives, although the exact composition of the first clade remains somewhat unclear; these three groups may in turn form a larger clade.
Linder and Rudall (2005) give a detailed discussion of morphological evolution and diversification in Poales; their tree differs in details from the one used here, but there are papers on Poales phylogeny due out soon, so perhaps things will be clarified a bit.

 PBIO 450 Lecture Notes - Commelinidae -- Spring 1999
The inclusion of Poaceae in the same order as Cyperaceae was done traditionally, but most authors (with the exception of Bremer et al., 1998, 1999) over the last half century have preferred to maintain the two as separate orders.
The current rbcL data supports this conclusion, and in fact isolates the Poales from the Cyperales with the Restionales positioned between the two.
As Cronquist's (1981: 1134) noted himself the tradition of accepting two order was "conditioned in large part by the obvious relationship of the Poaceae to the Restionaceae, and the Cyperaceae to the Juncaceae" and yet he goes on to conclude (p.

Development of genomic resources for and their application to the Asparagales are challenging because of huge nuclear genomes and the relatively long generation times required to develop genetically defined families.
Alignments of onion ESTs, Poales ESTs, and genomic sequences from rice were used to design oligonucleotide primers amplifying genomic regions from asparagus, garlic, and onion.
Initial mapping revealed no obvious synteny at the recombinational level between onion and rice, indicating that genomic resources developed for the Poales may not be applicable to the monocots as a whole.

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.
