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. In addition the JBEI-engineered plants are developmentally normal. 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. The JBEI-engineered plants present less lignin or phenolics than control plants and lack the defects of other engineered species making them a superior biofuel feedstock. The Joint BioEnergy Institute (JBEI www.jbei.org) is a scientific partnership led by the Lawrence Berkeley National Laboratory and including the Sandia National Laboratories the University of California campuses of Berkeley and Davis the Carnegie Institution for Science and the Lawrence Livermore National Laboratory. JBEI\'s primary scientific mission is to advance the development of the next generation of biofuels.
