Signal values of actin-1, LSD1, GAPDH, SDHA, TPB, RPS27α, HSP, Ubiquitin, Os.1322.1.S1_at and Os.145.1.S1_a_at in the microarray data. Among the eight frequently-used reference genes, TBP and Ubiquitin were more stably expressed than the others under BPH infestation. Os.1322.1.S1_at (Os05g23860) and Os.145.1.S1_a_at (Os02g56000) are two newly identified references with stable expressions under BPH infestation. Error bars indicate standard deviations of three biological replicates
