  1. aLabel incorporation in H-lignin was not considered as a criterion during the model calibration. The recorded experimental value in the [U-13C9]phenylalanine feeding experiment is greater than the reported label level in phe, which is 35% [29]. As a consequence, we deemed the measurement unreliable and did not use labeled H-lignin measurements
