Fig. 6. CsPrx25 positively regulates cell wall lignin biosynthesis.

Transcripts of the genes involved int he phenylpropanoid pathway, including HCT (a), CAD6 (b) and CCoAOMT (c), in WT vs. OE plants at 12 h after mock (ddH₂O) inoculation (filled bars) or Xcc (open bars) infection. d Spectroscopic analysis of lignin at 12 hpi. Leaves of OE1, OE2 and WT plants were sampled for lignification analysis. In a–d, the values were statistically compared with those found for the WT lines. The differences between the mock- and Xcc-infected samples were analyzed by Fisher’s LSD test, *P < 0.05; **P < 0.01. The differences between the OE and WT plants were analyzed using Tukey’s HSD test (P = 0.05; n = 3)
