Rosaceae Family Unigene v4

Overview
Analysis NameRosaceae Family Unigene v4
MethodCAP3
SourceGenbank Rosaceae ESTs (Jan 1, 2008)
Date performed2008-01-01

Many sequencing projects around the world are depositing ESTs from Rosaceae in the NCBI dbEST database. The Rosaceae ESTs included in this assembly were downloaded on January 1, 2008. Not all of these 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 CAP3 1 program. For some sequences, we were able to obtain the original trace files and incorporate the phred quality values for each base into the assembly.

The final assembly has been annotated by BLAST sequence similarity searching 2 against Swiss-Prot 3and TrEMBL 3. We will also provide homology information for TAIR 4's Arabidopsis proteins, Poplar and Vitis proteins in the near future.

Homology

Homology was determined using the BLASTx algorithm for the Rosaceae Contigs and Singlets vs. the Swiss-Prot and TrEMBL databases. 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.

Microsatellite Analysis

The type and frequency of simple sequence repeats in this unigene assembly (V4) were determined using the CUGIssr.pl 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.

Contig GO Terms

The GO Terms (www.geneontology.org) were determined by comparing the contigs against Swiss-Prot using BLAST. The Sprot2GO annotation file was then used to map go terms to the sequences using relevant matches (1e-9).
