abstract |
This disclosure relates to naturally occurring, naturally occurring corn mutant 2 (CAD2) alcohol dehydrogenase genes whose modified genes contribute to the bm1 corn phenotype in particular maize lines. In some embodiments, compositions and methods are provided that utilize a nucleic acid molecule comprising a mutant CAD2 gene and / or markers linked to a mutant CAD2 gene. In addition, plants obtained by genetic engineering with brown rib (phenotype) phenotype with reduced lignin characteristics, increased digestibility and ethanol yield are provided. |
