Gene Impacting Biomass Formation and Recalcitrance and Methods of Use

摘要

The invention provides plants having improved biomass properties of increased biomass quantity and density, increased cellulose content and deceased lignin content and improved sugar release efficiency, methods of generating (genetically modifying) and/or selecting (natural variant collections) plants with such preferred attributes of cellulose, lignin and sugar release, and uses of such plants. The inventors have determined that the expression of the gene, Potri.001G375700 (belonging to IQD signaling protein family containing a canonical calmodulin-binding domain) and/or activity of Potri.001G375700, modulates cellulose, lignin synthesis, sugar release and growth in plants.

1. A method of selecting a plant for improved biomass characteristics comprising:
a. obtaining nucleic acids from a candidate plant; b. detecting the a plant with modified expression and function of presence of an allelic variant of the Porti.001G375700 gene in said nucleic acids; and c. selecting said plant based on the presence of an allelic variant of the Porti.001G375700 gene in the nucleic acids obtained from the plant.
