ADL, acid detergent lignin; IVTDMD, in vitro true dry matter digestibility. *The transgenic and control plants were harvested after 6-month growth in the greenhouse. Value are mean ± SE (n = 3). One or two asterisks indicate significance corresponding to P < 0.05 or 0.01 (one way ANOVA, Dunnett’s test).
