GDR (Genome Database for Rosaceae): integrated web-database for Rosaceae genomics and genetics data

Area of Science:

• Genomics
• Bioinformatics
• Plant Science

Background:

• The Rosaceae family, encompassing economically significant species like apple, cherry, and strawberry, requires a centralized resource for genetics and genomics data.
• Existing data is often fragmented, hindering comprehensive analysis and comparative studies.

Purpose of the Study:

• To establish and maintain the Genome Database for Rosaceae (GDR) as a comprehensive repository for Rosaceae genetics and genomics information.
• To integrate diverse data types, including ESTs, genetic maps, and physical maps, to facilitate research.

Main Methods:

• Curating and integrating publicly available Rosaceae ESTs (Expressed Sequence Tags).
• Developing annotated databases for genetic maps, physical maps (peach), markers, and traits.
• Assembling ESTs into unigene sets for genera and the entire Rosaceae family.
• Implementing comparative mapping tools (CMap) and physical map viewers (WebFPC/WebChrom).
• Providing online analysis tools: batch BLAST/FASTA server, sequence assembly, microsatellite, and primer detection.

Main Results:

• GDR hosts annotated ESTs, a genetically anchored peach physical map, Rosaceae genetic maps, and annotated markers/traits.
• Unigene sets for each genus and the entire Rosaceae family are available.
• Data includes putative gene function, microsatellites, SNPs, Gene Ontology terms, and map positions.
• Comparative and physical map visualization tools are integrated.
• Online analysis tools enhance data utility for researchers.

Conclusions:

• GDR serves as a vital, integrated hub for Rosaceae genetics and genomics research.
• The database facilitates data exploration, comparative analysis, and discovery through visualization and analysis tools.
• GDR supports research on important agricultural crops within the Rosaceae family.
