Energy Crops Engineered for Increased Sugar Extraction through Inhibition of snl6 Expression

Lawrence Berkeley National Laboratory

Contact LBL About This Technology

Technology Marketing Summary

Pamela Ronald and a team of researchers at the Joint BioEnergy Institute (JBEI) have engineered plants with inhibited expression of snl6, a cinnamoyl-CoA reductase-like (CCR-like) gene. As a result, the JBEI plants have reduced lignin or phenolic compounds compared to wild type plants and yield an increase of up to 10 percent of sugar extracted. The JBEI technology can be applied to a wide range of plants including rice, miscanthus, switchgrass, sugarcane, sugar beet, sorghum and corn, among others.

 

 

Description

Lignin significantly hinders the extraction of sugars from plant cells walls for saccharification, a key step in the production of biofuels from cellulosic biomass. The JBEI-engineered plants are developmentally normal, but present less lignin or phenolics than control plants and lack the defects of other engineered species making them a superior biofuel feedstock.  Until now, plants with decreased lignin content have exhibited defects such as reduced size or sturdiness that made them unsuitable biofuel feedstocks.  Lignin significantly hinders the extraction of sugars from plant cells walls for saccharification, a key step in the production of biofuels from cellulosic biomass.

Benefits

Reduced lignin or phenolic compounds compared with wild type plants, up to a 10 percent increase in sugar extracted, yields developmentally normal plants, enables more efficient biofuel production.

INHIBITION OF SNL6 EXPRESSION FOR BIOFUEL PRODUCTION
The invention provides compositions and methods for inhibiting the expression of the gene Snl6 in plants. Plants with inhibited expression of Snl6 have use in biofuel production, e.g., by increasing the amount of soluble sugar that can be extracted from the plant.
