Relative expression pattern of potential candidate genes located within the total panicle weight (TPW) QTLs.

Heatmap displays the differentially expressed candidate genes in root and shoot tissue from genotypes harboring advantageous/disadvantageous alleles, and under P, N, or both deficiency condition. Statistical significance was determined by two-way ANOVA and Tukey’s tests. Asterisks indicates significance levels (***, **, *, ns: p<0.001, 0.01, 0.05, non-significant, respectively). Values were normalized to control treatment in accession with disadvantageous allele, in each tissue (square). adv: advantageous allele (G-38, G-355, G-1103), disadv: disadvantageous allele (X265, IR64, G-61, G-97).
