#29	46.21 ± 0.11*	16.73 ± 0.26	20.37 ± 0.69	6.45 ± 0.12	2.75 ± 0.01	241.82 ± 7.17	532.77 ± 9.68

Values are means ± SE. SEs represent two biological replicates. WT, wild type; #2, BLH6a:SRDX overexpression transgenic poplar line 2; #29, transgenic line 29. The asterisk represents the significant increase of cellulose content in #29 by the Student's t-test (

^*p < 0.05).
