Table 4.
Lignin content of extract-free poplar stems from BdPMT1-OE lines obtained in the WT and AtF5H-OE backgrounds, as compared to their respective controls
| Line | KL (%) | ABL (%) |
|---|---|---|
| WT control | 21.82 (0.21)a | 19.18 (0.33)ab |
| BdPMT1-OE/WT line 9 | 21.22 (0.09)a | 18.77 (0.50)b |
| BdPMT1-OE/WT line 17 | 21.60 (0.21)a | 19.47 (0.44)ab |
| BdPMT1-OE/WT line 31 | 21.09 (0.43)a | 19.27 (0.28)ab |
| AtF5H-OE control | 20.86 (0.23)a | 19.95 (0.23)a |
| BdPMT1-OE/AtF5H-OE line 21 | 20.87 (0.69)a | 19.86 (0.13)a |
The data represent mean (sd) values from biological triplicates. Different letters in columns indicate significant differences (Duncan test, P < 0.01). The lignin content is expressed as weight percentage of the sample and was determined using the KL and the ABL methods
