Abstract
The present invention relates to a mutant plant Cinnamoyl-CoA Reductase (CCR) protein capable of restoring the yield penalty in plants with lignin traits such as ccr-related deficiencies and methods and uses thereof. More specifically, the invention relates to plants lacking functional wild type CCR protein but having a weak ccr allele resulting in lower lignin amounts and increased saccharification, further accompanied by plant growth restoration of the lignin modification-induced dwarfism.
Claims15
A nucleic acid molecule encoding a mutant plant cinnamoyl-coA reductase (CCR) protein,
- wherein the encoded mutant plant CCR protein is mutated in a conserved domain having the sequence of SEQ ID NO:1, or in a domain having at least 70% amino acid identity with the conserved domain, and
- wherein the mutation comprises a deletion of at least one amino acid at a position corresponding to one of position(s) 98 to 100 of the conserved domain or the domain having at least 70% amino acid identity with the conserved domain.
