Genome analysis of South American Elymus (Triticeae) and Leymus (Triticeae) species based on variation in repeated nucleotide sequences

Characterization of genome in tetraploid StY Elymus (Triticeae: Poaceae) species using Sequential FISH and GISH

A Y genome specific STS marker in Pseudoroegneria and Elymus species (Triticeae: Gramineae).

The tribe Triticeae Dumortier in the grass family (Poaceae) includes the most important cereal crops (e.g., wheat, barley, and rye) and some economically important forage grasses. Elymus L. is the largest and most complex genus in the Triticeae tribe with approximately 150 species occurring worldwide. The genomic constitutions of approximately 40% of Elymus species are unknown and some have unv...

Allopolyploids of the Genus Elymus (Triticeae, Poaceae): a Phylogenetic Perspective

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...

Isoenzyme variation and genetic relationships between Elymus repens, E. hispidus and E. ×mucronatus (Triticeae, Poaceae)

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 isoe...

Molecular genetic linkage maps for allotetraploid Leymus wildryes (Gramineae: Triticeae).

Molecular genetic maps were constructed for two full-sib populations, TTC1 and TTC2, derived from two Leymus triticoides x Leymus cinereus hybrids and one common Leymus triticoides tester. Informative DNA markers were detected using 21 EcoRI-MseI and 17 PstI-MseI AFLP primer combinations, 36 anchored SSR or STS primer pairs, and 9 anchored RFLP probes. The 164-sib TTC1 map includes 1069 AFLP ma...
