Isoenzyme variation and genetic relationships between Elymus repens, E. hispidus and E. ×mucronatus (Triticeae, Poaceae)
نویسندگان
چکیده
Polyacrylamide gel electrophoresis (PAGE) was employed to examine the variation of ten isoenzyme markers in an attempt to assess the systematic and genetic relationships between Elymus repens, E. hispidus and their hybrid E. ×mucronatus. It was found that the hybrid shared most isoenzyme profiles and isoforms of its parents and high genetic affinity among the studied taxa was revealed. The isoenzyme structure of the hybrid resembled rather the structure of E. repens. Two alternative interpretations of systematic and genetic relationships among the hybrid E. ×mucronatus and its parents are discussed.

Allohexaploidy, introgression, and the complex phylogenetic history of Elymus repens (Poaceae).
The phylogenetic position of hexaploid Elymus repens within the tribe Triticeae (Poaceae) was examined using cloned sequences from the low-copy nuclear genes encoding phosphoenolpyruvate carboxylase (pepC) and beta-amylase. A previous analysis of E. repens using data from the nuclear granule-bound starch synthase I (GBSSI) gene had yielded five phylogenetically distinct gene copies, two more th...

Four accessions of hexaploid Elymus repens from its native Central European distribution area were analyzed using sequencing of multicopy (internal transcribed spacer, ITS) and single-copy (granule-bound starch synthase I, GBSSI) DNA in concert with genomic and fluorescent in situ hybridization (GISH and FISH) to disentangle its allopolyploid origin. Despite extensive ITS homogenization, nrDNA ...

Recent molecular phylogenetic studies of polyploid plants have successfully clarified complex patterns of reticulate evolution. In this study of Elymus repens, an allohexaploid member of the wheat tribe Triticeae, chloroplast and nuclear DNA data reveal an extreme reticulate pattern, revealing at least five distinct gene lineages coexisting within the species, acquired through a possible combin...

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...
متن کاملPhylogenetic analysis of North American Elymus and the monogenomic Triticeae (Poaceae) using three chloroplast DNA data sets.
Although the monogenomic genera of the Triticeae have been analyzed in numerous biosystematic studies, the allopolyploid genera have not been as extensively studied within a phylogenetic framework. We focus on North American species of Elymus, which, under the current genomic system of classification, are almost all allotetraploid, combining the St genome of Pseudoroegneria with the H genome of...
