Gene duplication is a major contributor to the origin of adaptive evolutionary novelties. Small-scale duplications can be created by chromosome segmental duplications, a DNA-mediated mechanism (reviewed in, or through reverse transcription of mature RNA intermediates, a mechanism known as retrotransposition or retroduplication of mRNAs.
Displays information about genes including functional, structural and expression data and also about given cDNA clone (also known as an Expressed Sequence Tag or EST) including putative ID, the size of the insert, vector information, and links to BLAST searches and genome browsing tools. SOURCE is a database which contains two type of page, Gene Reports (gene information) ans CloneReports (cDNA Clone Information).
Deals with information related to indica complementary DNA (cDNA) clones and their sequences in rice. RICD intends to furnish data to facilitate research about rice functional or comparative genomics research. The repository provides multiple searching features including by BLAST, keywords or chromosomes position. The database displays a three-parts page about each clone that gathers general information, sequence and related open reading frame (ORF) information, single nucleotide polymorphisms (SNPs) and InDels information, and the results of similarity search.
