Genes with a preferential expression in locular tissue (ratio [L/M] > 2).
Genes with a preferential expression in mesocarp (ratio [L/M] < 0.5). Genes were classified in BINs according to MapMan classification (Thimm et al., 2004).
Central metabolism-related BINs: major carbohydrates (BIN 2), minor carbohydrates (BIN 3), glycolysis (BIN 4), fermentation (BIN 5), gluconeogenesis/glyoxylate cycle (BIN 6), OPP cycle (BIN 7), TCA/organic acid transformations (BIN 8), mitochondrial electron transport/ATP synthesis (BIN 9).
Other metabolism-related BINs: nitrogen assimilation (BIN 12), metal handling (BIN 15), cofactor/vitamin synthesis (BIN 18), tetrapyrole synthesis (BIN 19), nucleotide metabolism (BIN 23), miscellaneous (BIN 26).
Regulation of protein activity-related BINs: protein targeting (BIN 29.3), protein posttranslational modification (BIN 29.4), protein degradation (BIN 29.5).
