Downregulation of GAUT4 leads to reduced ferulate and lignin-carbohydrate cross-linking in switchgrass

Computer generated drawing of of gasoline and DNA on top of a field of grass.

Art Ragauskas’ research team discovered that the suppression of pectic gene in switchgrass resulted in the reduction of hemicellulose molecular size and the cross-linking between hemicellulose and lignin. This collaborated study with University of Georgia has highlighted the key roles of inter-biopolymer cross-linking in dictating the cell wall integrity of engineered feedstock.

This research is published in the journal Communications Biology.
