Gramene: a resource for comparative grass genomics
Gramene (http://www.gramene.org) is a comparative genome mapping database for grasses and a community resource for rice. Rice, in addition to being an economically important crop, is also a model monocot for understanding other agronomically important grass genomes. Gramene replaces the existing AceDB database 'RiceGenes' with a relational database based on Oracle. Gramene provides curated and ...
متن کاملGramene, a tool for grass genomics.
Gramene (http://www.gramene.org) is a comparative genome mapping database for grasses and a community resource for rice (Oryza sativa). It combines a semi-automatically generated database of cereal genomic and expressed sequence tag sequences, genetic maps, map relations, and publications, with a curated database of rice mutants (genes and alleles), molecular markers, and proteins. Gramene cura...
متن کاملComparative genomics in the grass family: molecular characterization of grass genome structure and evolution.
The genomes of grasses are very different in terms of size, ploidy level and chromosome number. Despite these significant differences, it was found by comparative mapping that the linear order (colinearity) of genetic markers and genes is very well conserved between different grass genomes. The potential of such conservation has been exploited in several directions, e.g. in defining rice as a m...
متن کاملImproved criteria and comparative genomics tool provide new insights into grass paleogenomics
In the past decade, a number of bioinformatics tools have been developed to perform comparative genomics studies in plants and animals. However, most of the publicly available and user friendly tools lack common standards for the identification of robust orthologous relationships between genomes leading non-specialists to often over interpret the results of large scale comparative sequence anal...
متن کاملComparative genomics of chalcone synthase and Myb genes in the grass family.
Most plant genes occur as members of multigene families where new copies arise through duplication. Duplicate genes that do not confer an adaptive advantage to the plant are expected to rapidly erode into pseudogenes owing to the accumulation of transpositions, insertion/deletion mutations and nucleotide changes. Nonfunctional copies will drift to fixation within a few million years and ultimat...
