The close relationship of Bambusoideae with Pooideae and Ehrhartoideae provides an opportunity for comparing gene evolution between these three groups of grasses.
Difficulties in distinguishing between these two functional groups of grasses have hindered paleoecological studies of grass-dominated ecosystems.
These shapes are often used to distinguish large groups of grasses from one another.
Spikelet structure is highly useful in the identification of grass species and genera, and it defines some large groups of grasses.
As in most other groups of grasses, polyploidy is common.
Our study showed that species assigned to the predefined functional groups of grasses and forbs differed in most studied traits.
At the end of the composting period, there were no significant differences between the 0%and10%0% straw grass composts, or the 30%and50%0% grass composts, but differences were significant between these two groups of grass composts.
We speculate that the main excretion pathway of the drug is through renal elimination, and the decreased kidney function in brackish water grass carps is likely responsible for the considerable difference in pharmacokinetics between the two groups of grass carps.
On the other hand, given the very strong grouping of the entire clade of transferred genes of grasses (including the basal grass Anomochloa), and that Joinvillea is the closely related sister group of grasses, its failure to group with the grass genes suggests separate transfers.
The wheat tribe Triticeae (Poaceae) is a diverse group of grasses representing a textbook example of reticulate evolution.
