World wheat grain yields increased substantially in the 1960s and 1970s because farmers rapidly adopted the new varieties and cultivation methods of the so-called 'green revolution'. The new varieties are shorter, increase grain yield at the expense of straw biomass, and are more resistant to damage by wind and rain. These wheats are short because they(More)
Genome size varies greatly across angiosperms. It is well documented that, in addition to polyploidization, retrotransposon amplification has been a major cause of genome expansion. The lack of evidence for counterbalancing mechanisms that curtail unlimited genome growth has made many of us wonder whether angiosperms have a "one-way ticket to genomic(More)
We initially analyzed 11 families of low- and middle-copy-number long terminal repeat (LTR) retrotransposons in rice to determine how their structures have diverged from their predicted ancestral forms. These elements, many highly fragmented, were identified on the basis of sequence homology and structural characteristics. The 11 families, totaling 1000(More)
Comparative genetic studies have demonstrated that gene content and orders are highly conserved, both at the map and megabase level, between different species within the grass family. Integration of the genetic maps of rice, foxtail millet, sugar cane, sorghum, maize, the Triticeae cereals and oats into a single synthesis reveals that some chromosome(More)
An RFLP-based genetic map of Secale Cereale has provided evidence for multiple evolutionary translocations in the rye genome relative to that of hexaploid wheat. DNA clones which have previously been mapped in wheat indicated that chromosome arms 2RS, 3RL, 4RL, 5RL, 6RS, 6RL, 7RS and 7RL have all been involved in at least one translocation. A possible(More)
We generated a high-quality reference genome sequence for foxtail millet (Setaria italica). The ∼400-Mb assembly covers ∼80% of the genome and >95% of the gene space. The assembly was anchored to a 992-locus genetic map and was annotated by comparison with >1.3 million expressed sequence tag reads. We produced more than 580 million RNA-Seq reads to(More)
The construction of comparative genetic maps of chromosomes 4Am and 5Am of Triticum monococcum and chromosomes of homoeologous groups 4, 5 and 7 of T. aestivum has provided insight into the evolution of these chromosomes. The structures of chromosomes 4A, 5A and 7B of modern-day hexaploid bread wheat can be explained by a 4AL/5AL translocation that occurred(More)
In eukaryotes, tandem arrays of simple-sequence repeat sequences can find applications as highly variable and multi-allelic PCR-based genetic markers. In hexaploid bread wheat, a large-genome inbreeding species with low levels of RFLP, di- and trinucleotide tandem repeats were found in 22 published gene sequences, two of which were converted to PCR-based(More)
Comparative analyses unravel the relationships between genomes of related species. The most comprehensive comparative dataset obtained to date is from the grass family, which contains all of the major cereals. Early studies aimed to identify chromosomal regions that have remained conserved over long evolutionary time periods, but in recent years,(More)
