The ASRG database: identification and survey of Arabidopsis thaliana genes involved in pre-mRNA splicing

Genome Biol. 2004;5(12):R102. doi: 10.1186/gb-2004-5-12-r102. Epub 2004 Nov 29.


A total of 74 small nuclear RNA (snRNA) genes and 395 genes encoding splicing-related proteins were identified in the Arabidopsis genome by sequence comparison and motif searches, including the previously elusive U4atac snRNA gene. Most of the genes have not been studied experimentally. Classification of these genes and detailed information on gene structure, alternative splicing, gene duplications and phylogenetic relationships are made accessible as a comprehensive database of Arabidopsis Splicing Related Genes (ASRG) on our website.
