Apoplastic pH and monolignol addition rate effects on lignin formation and cell wall degradability in maize.

Monolignol polymerization rate and apoplastic pH and may influence the formation of lignin and its interactions in cell walls. Primary maize walls were artificially lignified by gradual "end-wise" or rapid "bulk" polymerization of coniferyl alcohol at pH 4 or 5.5. Lignification efficiency was greatest for end-wise polymers at pH 5.5 (90-98%), intermediate… (More)
