Spatiotemporal expression profiles of BnaNPFs across developmental stages by RNA-seq. Ro = root, St = stem, LeY = young leaf, LeO = old leaf, Hy = hypocotyl, Ao = anthocaulus, Cal = calyx, Cap = capillament, Pe = petal, Sta = stamen, Pi = pistil, Sp = silique pericarp, Se = seed, Sc = seed coat, Em = embryo, Co = cotyledon, GS = germination seeds; h, d, s, b, i, and f indicate hour, day, seedling, budding, initial flowering, and full-bloom stages, respectively. Color bar at the bottom represents log2 (FPKM > 1) expression value. The log2 (FPKM > 1) values of BnaNPFs were visualized by the R package and listed in Additional file 11: Table S6
