An alloplasmic wheat line, TA5536, with the "zebra" chromosome z5A was isolated from an Elymus trachycaulus/Triticum aestivum backcross derivative. This chromosome was named "zebra" because of its striped genomic in situ hybridization pattern. Its origin was traced to nonhomologous chromosome 5A of wheat and 1H(t) of Elymus; four chromatin segments were derived from chromosome 1H(t) and five ch...

Artificial grasslands play a role in carbon storage on the Qinghai-Tibetan Plateau. The artificial grasslands exhibit decreased proportions of graminate and increased species richness with age. However, the effect of the graminate proportions and species richness on ecosystem C stocks in artificial grasslands have not been elucidated. We conducted an in situ13C pulse-labeling experiment in Augu...

As a result of an invasion by the native grass Elymus athericus (Link) Kerguélen (Poaceae) in the last 10 years, a major change in vegetation cover has occurred in salt marshes of the Mont Saint-Michel bay, Western France. The impact of such an invasion on carabid assemblages, a dominant group of terrestrial arthropods in these habitats and containing several stenotopic species, is investigated...

Significance to the Landscape and Nursery Industries In the face of California’s rapid population growth, the competition for increasingly limited water resources has necessitated the use of recycled water for landscape and nursery irrigation. A reference list of the sensitivity of plant species to recycled water would facilitate implementation of recycled water irrigation. The information gene...

The system of the family Poaceae is dynamically changing due to progress phylogenetic research. Consequently, nomenclature some taxa should be adjusted accordingly. In Plants World Online (POWO) and other authoritative online sources, genera nothogenera are accepted in rather wide circumscriptions; for example, ×Agroelymus E.G. Camus ex A. (including ×Agrotrigia Tzvelev ×Elymopyrum Cugnac), ×El...

The wheat tribe, Triticeae, includes many genomically distinct polyploid taxa. Elymus is an entirely allopolyploid genus, with all species containing the St genome of Pseudoroegneria. The St genome may be combined with one or more distinct genomes representing multiple, diverse diploid donors from throughout the tribe. This study includes a simultaneous phylogenetic analysis of new and previous...

Siberian wildrye (Elymus sibiricus L.) is a perennial, self-fertilizing grass that plays an important role in animal husbandry and environmental sustenance. However, the transcriptomic and genomic information on this species is very limited, which hinders genetic and breeding studies. In the present study, 76,686,804 clean reads were generated from 11 different tissue samples of E. sibiricus by...

The phylogenetic relationships of 15 taxa from Hystrix and the related genera Leymus (NsXm), Elymus (StH), Pseudoroegneria (St), Hordeum (H), Psathyrostachys (Ns), and Thinopyrum (E) were examined by using the Giemsa C-banded karyotype. The Hy. patula C-banding pattern was similar to those of Elymus species, whereas C-banding patterns of the other Hystrix species were similar to those of Leymus...
