Fig. 4From: PdWND3A, a wood-associated NAC domain-containing protein, affects lignin biosynthesis and composition in PopulusAnalyses of Klason lignin content and the expression of lignin biosynthesis-related genes in OXPdWND3A transgenic plants. a Klason lignin (acid-insoluble lignin) content detected from leaf and stem tissues. b Relative gene expression of representative lignin biosynthesis-related genes in OXPdWND3A transgenic plants. Shown are the mean values of three biological replicates ± S.D. The asterisk marks the statistical significance against WV94 (p < 0.01, n = 3)Back to article page
