Methods and compositions for altering lignin composition in plants

Patent · 06 March 2018

OSTI ID:1425907

Srivastava, Avinash C.; Tang, Yuhong; Blancaflor, Elison

The invention provides methods for decreasing lignin content in plants by reducing expression of a folylpolyglutamate synthetase 1 (FPGS1) coding sequence in the plant. Also provided are methods for reducing lignin content in a plant by down-regulation of FPGS1 expression in the plant. Nucleic acid molecules for modulation of FPGS1 expression and transgenic plants the same are also provided. Plants described herein may be used, for example, as improved biofuel feedstock and as highly digestible forage crops. Methods for processing plant tissue and for producing biofuels by utilizing such plants are also provided.
