Diagram of FTFLPdb relational database schema. The rectangles represent core data object tables and lines represent relationships between the tables. The cardinality between tables is one (denoted as 1) to many (denoted as *) relationship. Noncore data object tables are not shown in the diagram for simplification. Table Gene stores genomic sequence of genes, protein sequence, and annotation of the sequences. Table GeneFeature stores the coordinates of gene features. Table ProteinDomain stores the mapping positions of functional domains to a protein. Table Primer stores the primer sequences and relevant information about the primers. Tables PCR, Construct, Plant, and Image store the information about PCR products, clones, transgenic plants, and still images as well as videos, respectively. Table GOAnnotation stores the GO annotations of Arabidopsis genes. Table TribelGeneFamily stores Gene family relationships.
