The unified grass genome: synergy in synteny.
The grasses, members of the family Gramineae or Poaceae, are represented by over 10,000 species (Kellogg and Birchler 1993). Three of the domesticated grasses, rice, wheat, and maize, account for about half of total world food production. Although the oldest known grass fossils have been found in paleocene-eocene deposits that are ∼50–60 million years old (Crepet and Feldman 1991), morphologica...
متن کاملPatterns in grass genome evolution.
Increasingly comprehensive, species-rich, and large-scale comparisons of grass genome structure have uncovered an even higher level of genomic rearrangement than originally observed by recombinational mapping or orthologous clone sequence comparisons. Small rearrangements are exceedingly abundant, even in comparisons of closely related species. The mechanisms of these small rearrangements, most...
متن کاملCubozoan genome illuminates functional diversification of opsins and photoreceptor evolution
Animals sense light primarily by an opsin-based photopigment present in a photoreceptor cell. Cnidaria are arguably the most basal phylum containing a well-developed visual system. The evolutionary history of opsins in the animal kingdom has not yet been resolved. Here, we study the evolution of animal opsins by genome-wide analysis of the cubozoan jellyfish Tripedalia cystophora, a cnidarian p...
متن کاملGene synteny and evolution of genome architecture in trypanosomatids.
The trypanosomatid protozoa Trypanosoma brucei, Trypanosoma cruzi and Leishmania major are related human pathogens that cause markedly distinct diseases. Using information from genome sequencing projects currently underway, we have compared the sequences of large chromosomal fragments from each species. Despite high levels of divergence at the sequence level, these three species exhibit a strik...
متن کاملTracing the Evolution of the Floral Homeotic B- and C-Function Genes through Genome Synteny
The evolution of the floral homeotic genes has been characterized using phylogenetic and functional studies. It is possible to enhance these studies by comparing gene content and order between species to determine the evolutionary history of the regulatory genes. Here, we use a synteny-based approach to trace the evolution of the floral B- and C-function genes that are required for specificatio...
