OrganismsRubus sp.

This is the fifth version of the Rubus unigene. This build  used  ESTs from the genus Rubus in the NCBI dbEST database. The Rubus ESTs included in this assembly were downloaded on July 1, 2012.

Not all of the Rubus ESTs are of high quality. To filter, we crossmatched the public sequences against NCBI's UniVec database and used the BLAST sequence similarity algorithm to remove species-specific chloroplast, mitochondrial, tRNA, and rRNA sequences. To reduce redundancy and create longer transcripts we assembled these ESTs using the CAP31 program (-p 90). The contigs from the assembly have been annotated by homology using BLASTX to the following protien datasets:  Swiss-Prot2, TrEMBL3TAIR Arabidopsis proteins4Prunus persica5Populus trichocarpa6, and Vitis vinifera7.

Homology analysis

Homology was determined using the BLASTx algorithm for the Rubus Contigs against the Swiss-Prot, TrEMBLTAIR Arabidopsis proteins, Prunus persica, Populus trichocarpa and Vitis vinifera proteins. Only matches with an E-value of 1.0 e-6 or better were recorded. Swiss-Prot is a curated protein database with a high level of annotation and a minimal level of redundancy, and TrEMBL is a computer-annotated supplement of Swiss-Prot that contains all the translations of TrEMBL nucleotide sequence entries not yet integrated in Swiss-Prot. Homology data for Rubus contigs is available in Excel format can be downloaded from the Downloads link.

KEGG analysis

KEGG analysis of Rubus unigene v5.0 contigs

All Rubus unigene v5.0 contigs were uploaded to the KEGG / KASS server at The SBH (single-directional best hit) method was selected under the category "Assignment method". All other settings were defaults. Results were downloaded in the heir.tar.gz heirarchy file and uploaded to the website.


Microsatellite analysis

The type and frequency of simple sequence repeats in Rubus unigene v5.0 contigs was determined using the program.For these searches, SSRs are defined as dinucleotides repeated at least 5 times, trinucleotides repeated at least 4 times, tetranucleotides repeated at least 3 times, or pentanucleotides repeated at least 3 times. The SSRs of Rubus unigene v5.0 contigs are available to be downloaded from the Downloads page.
