LettuceGDB: The community database for lettuce genetics and omics.

Area of Science:

• Plant genomics and bioinformatics
• Agricultural science
• Vegetable crop research

Background:

• Lettuce (Asteraceae family) is a globally significant vegetable with increasing multi-omics data.
• Existing data fragmentation hinders comprehensive research and breeding efforts.
• A centralized, integrated database is needed for efficient lettuce data management.

Purpose of the Study:

• To establish LettuceGDB, a comprehensive, user-friendly database for lettuce omics and phenotypic data.
• To provide integrated access to genomic resources, germplasm information, and research data.
• To facilitate data mining and database-driven exploration for lettuce science and breeding.

Main Methods:

• Development of a centralized database (LettuceGDB) with a user-friendly interface.
• Integration of two reference genomes, re-sequencing data (>1000 varieties), germplasm data (>1300 accessions), and phenotypic records.
• Inclusion of re-analyzed RNA sequencing datasets (256), miRNAome, metabolite, and epigenetic data.
• Implementation of five functional modules (Genome, Genotype, Germplasm, Phenotype, O-Omics) and eight built-in tools.

Main Results:

• LettuceGDB provides access to annotated reference genomes and re-sequencing data for over 1000 lettuce varieties.
• The database incorporates extensive germplasm, phenotypic, transcriptomic, metabolomic, and epigenomic data.
• User-friendly interface with five hierarchical functions and eight integrated tools facilitates data access and analysis.
• A community forum and research progress summary are included for knowledge sharing.

Conclusions:

• LettuceGDB serves as a comprehensive omics data hub, consolidating diverse lettuce data.
• The database empowers data mining and exploration, significantly aiding scientific research and crop improvement.
• LettuceGDB is a valuable resource for researchers and breeders working on lettuce genetics and genomics.
