Title: Plants with modified lignin content and methods for production thereof

Abstract

The invention provides methods for decreasing lignin content and for increasing the level of fermentable carbohydrates in plants by down-regulation of the NST transcription factor. Nucleic acid constructs for down-regulation of NST are described. Transgenic plants are provided that comprise reduced lignin content. 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 ethanol by utilizing such plants are also provided.

Methods and systems to produce lignin-modifying enzymes and uses thereof

Patent Khlystov, Nikita A.; Sattely, Elizabeth

Embodiments of the invention are generally directed to lignin-modifying enzymes and systems and methods of their manufacture. In many embodiments, the lignin-modifying enzymes are lignin-degrading enzymes capable of breaking down lignin into component parts that are usable for other purposes. Several embodiments are directed to systems for producing lignin-modifying enzymes in vivo, including in yeast and/or plant species, and certain embodiments are directed to methods of creating these systems, including transfecting the species to produce lignin-modifying enzymes.

Patent Wang, Huanzhong; Chen, Fang; Dixon, Richard A.

The invention provides methods for modifying lignin, cellulose, xylan, and hemicellulose content in plants, and for achieving ectopic lignification and, for instance, secondary cell wall synthesis in pith cells, by altered regulation of a WRKY transcription factor. Nucleic acid constructs for altered WRKY-TF expression are described. Transgenic plants are provided that comprise modified pith cell walls, and lignin, cellulose, and hemicellulose content. Plants described herein may be used, for example, as improved biofuel feedstock and as highly digestible forage crops.
