Welcome to PIECE! (PIECE 2.0 released)
PIECE is a plant gene structure comparison and evolution database with 25 species. Annotated genes were extracted from the species and classified based on Pfam motif. Phylogenetic tree was reconstructed for each gene category integrated exon-intron and protein motif information. Both the sequences and gene structure information for each identified gene are freely available for online access on the PIECE website.
Why use PIECE?
“The PIECE database can provide valuable information for plant researchers for the analysis of gene structure evolution and for elucidating the biological function of the proteins. We hope that PIECE may become a useful resource for the research community, especially in the study of gene exon-intron evolution.”
Now, the PIECE contains genes identified in 25 species. Genome sequences, transcript sequences and protein sequences were downloaded from Phytozome, TAIR, RAP and Genoscope.
