Expression levels of genes involved in several overrepresented biological processes. a and (b) indicated the expression levels of genes involved in light, hormone, hydrogen peroxide and stress responses, floral development and circadian rhythm in the NKR-04/− 05/− 06 hybrid triad and the Bro-10/− 11/− 12 hybrid triad, respectively. * indicated the relative expression levels of the genes in the hybrid were different from the MPV (p-value < 0.05). ** indicated the relative expression levels of the genes in the hybrid were significantly different from the MPV (corrected p-value < 0.05). The functional annotations of these genes were showed in Supplementary Table S2
