Expression analysis of lignin biosynthetic genes in inflorescence stems of the cse-2 mutant and the wild type as determined via RT-qPCR. The relative expression of each tested gene was normalized to that of the wild type. Error bars indicate the standard deviation. Differences in gene expression were assessed with Student’s t test (*0.05 > P > 0.01; **0.01 > P > 0.001; n = 4)
