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...
متن کاملIdentification of Fungus Resistant Wild Accessions and Interspecific Hybrids of the Genus Arachis
Peanut, Arachis hypogaea L., is a protein-rich species consumed worldwide. A key improvement to peanut culture involves the development of cultivars that resist fungal diseases such as rust, leaf spot and scab. Over three years, we evaluated fungal resistance under field conditions of 43 wild accessions and three interspecific hybrids of the genus Arachis, as well as six A. hypogaea genotypes. ...

Artificial and Natural Hybrids in the Gramineae, Tribe Hordeae. VII. Hybrids and Allopolyploids between Elymus Glaucus and Sitanion Spp.
N the first paper of this series (STEBBINS, VALENCIA and VALENCIA I 1946a) two different natural hybrids between Elymus glaucus and Sitanion jubatum were described. Both were intermediate between their parents and were completely sterile. They nevertheless had essentially normal meiosis, with the chromosomes forming 14 bivalents or occasionally 13 bivalents and 2 univalents at first metaphase. ...
متن کاملInterspecific Hybrids
The regulation of gene expression is essential for organismal form, function, and fitness. Complex organismal development from zygote to adult requires finely tuned expression of genes in space, time, and abundance. Proper expression of genes is also required for most other aspects of physiology and function. Even minor changes in gene expression have the potential to significantly impact pheno...
