Evolutionary dynamics of grass genomes
The grass family (Poaceae) has been the subject of intense research over the past decade. Although other angiosperm families contain more species and more genera, the Poaceae exceed all other families in ecological dominance and economic importance. Research has focused on the evolutionary relationships among grasses as well as the structure of grass genomes. Here I examine the evolutionary dyn...
متن کاملUpdate on Genomes of the Grass Family Synergy of Two Reference Genomes for the Grass Family
If one considers the Gordon Conference in Plant Genetics in 1997 as the origin of the international effort to sequence the rice (Oryza sativa) genome and the publication of the data in 2005 as the completion of production and analysis, it took about 8 years and 14 major laboratories from nine countries (International Rice Genome Sequencing Project, 2005). In the case of sorghum (Sorghum bicolor...
متن کاملColinearity and gene density in grass genomes.
Grasses are the single most important plant family in agriculture. In the past years, comparative genetic mapping has revealed conserved gene order (colinearity) among many grass species. Recently, the first studies at gene level have demonstrated that microcolinearity of genes is less conserved: small scale rearrangements and deletions complicate the microcolinearity between closely related sp...
متن کاملInsular Organization of Gene Space in Grass Genomes
Wheat and maize genes were hypothesized to be clustered into islands but the hypothesis was not statistically tested. The hypothesis is statistically tested here in four grass species differing in genome size, Brachypodium distachyon, Oryza sativa, Sorghum bicolor, and Aegilops tauschii. Density functions obtained under a model where gene locations follow a homogeneous Poisson process and thus ...
متن کاملActive retrotransposons are a common feature of grass genomes.
A large fraction of the genomes of grasses, members of the family Graminae, is composed of retrotransposons. These elements resemble animal retroviruses in their structure and possess a life cycle similar to theirs that includes transcription, translation, and integration of daughter copies. We have investigated if retrotransposons are generally transcribed in the grasses and other plants, and ...
