Phylogenetic relationships of the monogenomic species of the wheat tribe, Triticeae (Poaceae), inferred from nuclear rDNA (internal transcribed spacer) sequences.
The molecular data and biogeography of the tribe suggest that the Mediterranean lineage is derived from the Arctic-temperate lineage and that the two lineages have evolved in parallel. Expand
Phylogenetic relationships of 10 grass species: an assessment of phylogenetic utility of the internal transcribed spacer region in nuclear ribosomal DNA in monocots.
Phylogenetic trees of the 10 grass species generated from the ITS sequence data were in general agreement with phylogenies based on molecular data from ribosomal RNA and chloroplast DNA of similar grass taxa. Expand
Molecular phylogeny of the Pooideae (Poaceae) based on nuclear rDNA (ITS) sequences
The phylogenetic relationships of the seven pooid tribes inferred from the ITS sequences are highly concordant with the cytogenetic evidence that the reduction in chromosome number and the increase in chromosome size evolved only once in the pooids and pre-dated the divergence of the Poeae, Aveneae, Bromeae and Triticeae.

Carbohydrate Partitioning in 185 Accessions of Gramineae Grown Under Warm and Cool Temperatures
Fructan is an ancillary form of carbohydrate storage compatible with the hypothesis that fructan accumulation in the vacuole allows photosynthesis to continue at cool temperatures when other storage pools are saturated, and not at the expense of any other form of nonstructural carbohydrate. Expand
Variation in Mineral Concentration and Grass Tetany Potential among Russian Wildrye Accessions
Grass tetany or hypomagnesemic tetany in cattle (Bos taurus) is caused by an imbalance of K, Ca, and Mg in the diet. Indications of grass tetany range from reduced milk yield or weight gain toExpand
A Molecular Phylogeny of the Grass Family (Poaceae) Based on the Sequences of Nuclear Ribosomal DNA (ITS)
The ITS phylogeny of the grass family, and evidence from the chloroplast genome, cytogenetics, fossil records, biogeography, and plate tectonic theory, suggest that the origin of the Grasses is probably ‘out of South America’. Expand
Dry Matter Production of Orchardgrass and Perennial Ryegrass at Five Irrigation Levels
A line-source irrigation system was used from 1995 to 1998 to evaluate dry matter (DM) production and seasonal forage distribution of nine orchardgrass and perennial ryegrass hybrid cultivars along with check cultivars of meadow brome and smooth brome to find Tall fescue was most responsive (i.e., produced more DM production) to increased irrigalion rates.

Merits of native and introduced Triticeae grasses on semiarid rangelands
Experiments were conducted on four semiarid range sites to compare stand establishment, productivity, and persistence of several introduced perennial Triticeae grasses with that of their native counterparts, finding native grasses were more difficult to establish, less productive, and less persistent than the introduced grasses.

Host Plant Resistance to
One of eight high tannin cottons had more cotton leafperforator horseshoes than the DPL -61 check, but none had fewer, and among 25 early and miscellaneous breeding stocks and cultivars, only "Stoneville 213" and La Okra 500C had significantly less seasonal seed damage than DPL-61. Expand
Variation in Agronomic and Morphological Traits among Russian Wildrye Accessions
Russian wildrye [Psathyrostachys juncea (Fischer) Nevski] accessions in the U.S. National Plant Germplasm System have not been adequately characterized for agronomic and morphological traits. SuchExpand
