This order includes many species associated with livestock, such as sheep, goats, pigs, cows and camels, as well as species of giraffes, antelopes and deer.
This order includes relatively few genera, but some of them, e.g., Gracilaria, are species rich (Fredericq and Hommersand 1990).
This order includes the endemic Australian family Phascolarctidae, of which P. cinereus is the only living representative.
This order included a group of gymnosperms composed of the family Ginkgoaceae, which comprised approximately 15 genera that date from the Permian Period (about 300 to 250 million years ago) of the Paleozoic Era (about 360 to 250 million years ago).
We are committed to supporting all of our employees and anyone in their immediate family who may be impacted by this order, including assistance with legal counsel and support, and will continue to monitor any developments.
All of God's creations are part of this order, including humans.
It shares many traits common to members of this order, including the four fused teeth that form the characteristic beak and give the order its name (tetra=four, odous=tooth, and forma=shape).
To test the recently suggested hypothesis that the skeletonless Corallimorpharia are imbedded within the Scleractinia, we analyzed seven genera in this order, including members of both the Corallimorphidae and Discosomatidae [14].
However, genome sequencing of poplar [ 27], castor bean [ 28], cassava [ 29] and large EST libraries from other species within this order including flax (this study) will likely aid in molecular systematic studies to address broader phylogenetic relationships between these families.
However, cytogenetic studies of many species of this order (including E. danica that we included in our transcriptome analyses) have clearly reported that the centromeres are metacentric or acrocentric (Kiauta and Mol, 1977; Soldan and Putz, 2000).
This well-circumscribed order includes only a handful of genera, but is particularly species rich (e.g. Millar and Freshwater 2005), and it would be very interesting to explore the possible role of aneuploidy in their evolution by obtaining additional chromosome and genome size data for representative species.
