Blocking SA accumulation restores growth to HCT-RNAi Arabidopsis. (A) Fifteen-week-old plants grown in soil. (B) Rosette diameters and plant heights for the genotypes in A. (C) SA levels. Values with different letters are significantly different (P < 0.05). (D) Transcript levels of the HCT, PR5, PR1, and PR2 genes as determined by qRT-PCR. (E) Maüle staining of stem cross-sections. Note loss of red staining in interfascicular fibers in all lines expressing HCT-RNAi. 1, WT; 2, sid2-2 null mutant; 3, HCT-RNAi; 4, HCT-RNAi with heterozygous sid2-2; 5, HCT-RNAi with homozygous sid2-2; 6, WT × HCT-RNAi. (F) Extractable HCT enzyme activity. (G) Lignin content and composition as determined by thioacidolysis. H, hydroxyphenyl unit; G, guaiacyl unit; S, syringyl unit. Results are means ± SD of three biological replicates (each a pool of three plants of the same genotype).
