Predicted ¹³C₉ incorporation in lignin monomers (G, S, H, and Total) and lignin composition in BdPTAL knockdown following labeled Phe and Tyr feeding. The left and center panels compare model predictions and measured levels of label incorporation in transgenic BdPTAL plants in response to labeled Phe or Tyr feeding. The right panel shows changes in lignin composition relative to wild type, and compares model predictions with measured results
