Column values represent the number of unique features/sequences made available at PlantGDB. The protein column represents the sum of all cross-species homologous protein alignments. Each expressed sequence may be responsible for multiple features by alignment to multiple loci. BAC, bacterial artificial chromosome; Chr, chromosome; EST, expressed sequence tag; GSS, genome survey sequence; PUT, PlantGDB Unique Transcript.
