  1. DG, differentially expressed genes; grain yield-involved, genes involved in grain yield; GDMC-interaction, the grain yield-involved genes which negatively interacted with grain dry matter content; GDMC-involved, genes involved in grain dry matter content; n, number of genes; p, p-value for statistical significance. The symbol "-" represents data unavailable. The numbers in boldface represent significance at p < 0.05. The percentages in italics represent the first two largest categories in each set of genes.
