Recent developments in DNA sequencing have enabled the large and complex genomes of many crop species to be determined for the first time, even those previously intractable due to their polyploid nature. Indeed, over the course of the last 2 years, the genome sequences of several commercially important cereals, notably barley and bread wheat, have become available, as well as those of related w...

Analysis of intraspecies diversity in wheat and barley genomes identifies breakpoints of ancient haplotypes and provides insight in the structure of diploid and hexaploid Triticeae gene pools Abstract A large number of wheat and barley varieties have evolved in agricultural ecosystems since domestication. Because of the large, repetitive genomes of these Triticeae crops, sequence information is...

The trait flowering time regulated by genes determining vernalisation and photoperiod sensitivity was used as an example for presenting data on comparative major gene and QTL mapping within the Triticeae. The major genes are shown to be members of homoeologous series. Furthermore it was demonstrated that in genome regions carrying major genes also QTLs for the same traits were detected.

Receptor-like kinases (RLKs) play broad biological roles in plants. We report on a conserved receptor-like protein kinase (RPK) gene from wheat and other Triticeae species. The TaRPK1 was isolated from the Triticum aestivum cv. Prins - Triticum timopheevii introgression line IGVI-465 carrying the powdery mildew resistance gene Pm6. The TaRPK1 was mapped to homoeologous chromosomes 2A (TaRPK1-2A...

To better understand genetic events that accompany allopolyploid formation, we studied the rate and time of elimination of eight DNA sequences in F1 hybrids and newly formed allopolyploids of Aegilops and TRITICUM: In total, 35 interspecific and intergeneric F1 hybrids and 22 derived allopolyploids were analyzed and compared with their direct parental plants. The studied sequences exist in all ...
