A large number of wheat (Triticum aestivum) and barley (Hordeum vulgare) varieties have evolved in agricultural ecosystems since domestication. Because of the large, repetitive genomes of these Triticeae crops, sequence information is limited and molecular differences between modern varieties are poorly understood. To study intraspecies genomic diversity, we compared large genomic sequences at ...
Polyploidization is one of the major driving forces in plant evolution and is extremely relevant to speciation and diversity creation. Polyploidization leads to a myriad of genetic and epigenetic alterations that ultimately generate plants and species with increased genome plasticity. Polyploids are the result of the fusion of two or more genomes into the same nucleus and can be classified as a...
BACKGROUND AND AIMS When root-zone O(2) deficiency occurs together with salinity, regulation of shoot ion concentrations is compromised even more than under salinity alone. Tolerance was evaluated amongst 34 accessions of Hordeum marinum, a wild species in the Triticeae, to combined salinity and root-zone O(2) deficiency. Interest in H. marinum arises from the potential to use it as a donor for...
