UgMicroSatdb: database for mining microsatellites from unigenes

Microsatellites, also known as simple sequence repeats (SSRs) or short tandem repeats (STRs), have extensively been exploited as molecular markers for diverse applications. Recently, their role in gene regulation and genome evolution has also been discussed widely. We have developed UgMicroSatdb (Unigene MicroSatellite database), a web-based relational database of microsatellites present in uni...

Mining functional microsatellites in legume unigenes

Highly polymorphic and transferable microsatellites (SSRs) are important for comparative genomics, genome analysis and phylogenetic studies. Development of novel species-specific microsatellite markers remains a costly and labor-intensive project. Therefore, interest has been shifted from genomic to genic markers owing to their high inter-species transferability as they are developed from conse...

Identification of microsatellites in cattle unigenes.

To identify EST-SSR molecular markers, 41,986 cattle UniGene sequences from NCBI were mined for analyzing SSRs. A total of 1,831 SSRs were identified from 1,666 ESTs, which represented an average density of 19.88 kb per SSR. The frequency of EST-SSRs was 4.0%. The dinucleotide repeat motif was the most abundant SSR, accounting for 54%, followed by 22%, 13%, 7% and 4%, respectively, for tri-, he...

Mining, characterization and validation of EST derived microsatellites from the transcriptome database of Allium sativum L

Expressed Sequence Tags (ESTs) with comprehensive transcript information are valuable resources for development of molecular markers as they are derived from conserved genic regions. The present study highlights the mining of EST database to deduce the class I hyper variable SSRs in A. sativum. From 21694 garlic EST sequences, 642 non-redundant SSRs were identified with an average frequency of ...

MICdb: database of prokaryotic microsatellites

The MICdb (Microsatellites Database) (http://www.cdfd.org.in/micas) is a comprehensive relational database of non-redundant microsatellites extracted from fully sequenced prokaryotic genomes. The current version (1.0) of the database has been compiled from 83 genomes belonging to different phylogenetic groups. This database has been linked to MICAS, the web-based Microstatellite Analysis Server...
