WebEffects of COMT Suppression on Lignin Content, Composition and Plant Growth. We examined lignin content and lignin monomer composition in whole tillers (including stem, leaf, and sheath) and stems of transgenic switchgrass. In the T0 generation, transgenic lines T0-2, T0-3, and T0-12 showed significant re- WebDec 24, 2024 · Down regulation of COMT has been found to alter the lignin composition as well as reduction in lignin content (Chen et al. 2004). COMT also exhibited a significant (p ≤ 0.05) correlation with total phenol (r = 0.983) (Table 1) suggesting that COMT plays an exclusive role in synthesis of phenolic compounds in the phenylpropanoid pathway. …
