Biological processes enrichment of genes located in regions with a Z(H _P) < -4. a All of the genes in regions with a Z(H _P) < -4 were divided into 3 groups: I, Z(H _P)_M < -4 (605 genes); II, Z(H _P)_S < -4 (567 genes); and III, Z(H _P)_D < -4 (605 genes). b, c, d, e and f indicate the biological process enrichment of genes belonging to all 3 groups; belonging to both group II and III; belonging to only group I; belonging to only group II and belonging to only group III. Important enriched terms are color coded to reflect the relatedness of biological processes. Orange, nervous system development; red, reproductive process; yellow, muscle contraction; blue, various processes related to stress responses; green, ear development; grey, immune system development and regulation; pink, regulation of multicellular organism growth
