browser is a dynamic graphical display used to browse genomes.Use it to:Search for genes and other features identified from the Rice-Japonica,Maize and Arabidopsis genomes,as well as features from maize,sorghum,barley and wheat that were mapped on the rice genome.View the location of a particular feature on the rice genomeExamine neighboring genes and markers.View the gene model of a candidate gene of interest in order to design primers.Identify the genomic sequence to which a particular gene is mapped.Look for synteny.Compare the position of features from other species with the location of genes in the rice genome,such as sequenced genetic markers,ESTs,cDNAs,CDSs,genes,insertion and repeat elements.Gramene Genome BrowserAugust2005Link to maps and ontologies from the genome
