     a transgenic poplar, in which the rabg3bca gene from arabidopsis was overexpressed, was analyzed for its biomass composition and enzymatic digestibility after chemical pretreatment. in comparison with a wild-type poplar (wt), the transgenic poplar (ox8) showed 9.8% higher glucan content. the levels of other biomass components did not differ greatly between wt and ox8. when wt and ox8 samples were pretreated by sulfuric acid (1%, w/v at 190 °c), sodium hydroxide (1%, w/v at 190 °c), or ammonia (14%, w/w at 80 °c), the washed pretreated solids of ox8 exhibited a higher enzymatic digestibility than those of wt in each chemical pretreatment. the sodium hydroxide pretreatment was the most effective among the three pretreatment processes, showing 58.7% and 69.4% of theoretical glucose yield from the saccharification of pretreated ox8 and wt, respectively. the transgenic poplar, growing faster and taller, was found to contain more glucan and have a higher enzymatic digestibility than wt.
