Figure 9. Expression profiles of the OsBBX genes in response to phytohormone treatments.

(A) Hierarchical cluster displaying the differentially expressed OsBBX genes under NAA, GA₃ and KT treatments. The color key at the left represents the log₂-based expression values. (B) The qPCR verification of some of the differentially expressed OsBBX genes. The x-axis indicates the treatment. The y-axis shows the relative expression level of each treatment compared to control. The error bars indicate the standard deviations of the independent biological replicates.
