Schematic model of gene regulatory networks for the grain size and chalkiness formation of osphyb. Pathway: Glycolysis, TCA cycle, starch synthesis, amino acid metabolism, fatty acid synthesis, plant hormones, oxidative phosphorylation, antioxidation, translation regulation. Genes encoding enzyme (s) are indicated in orange boxes, metabolites and other materials in white boxes. The expression patterns of the genes encoding corresponding enzyme (s) are indicated above or below the arrows. Each row (6 boxes) represents a DEG. Six boxes in each row represent 3 biological repeats of one gene in NIP (first three boxes) and osphyb (last three boxes), respectively. The enriched DEGs boxes for 40S, 50S, 60S, Ribosome biogenesis and RNA polymerase are rotated 90° clockwise. Log₂ (fold changes) are represented by a colour scale from green (down-regulated) to red (up-regulated)
