Fig. 7From: Characterization of B-BOX gene family and their expression profiles under hormonal, abiotic and metal stresses in Poaceae plantsInducible expression profile of rice BBX gene family members in response to heavy metals. (A), Chromium (Cr); (B), Cadmium (Cd); (C), Nickel (Ni); (D), Iron (Fe), respectively. The x-axis indicates the treatment. The y-axis shows the relative expression level of each treatment compared to control (0h). The error bars indicate the standard deviations of the three independent qRT-PCR biological replicates. Small letters (a–e) represent significant difference (p < 0.05)Back to article page
