GENETICALLY MODIFIED PLANTS HAVING ALTERED LIGNIN CONTENT

摘要

The invention relates to methods for producing a plant with altered lignin content by genetically manipulating expression of a PIRIN gene. The said method comprises (a) altering expression of a gene encoding a PIRIN2 polypeptide in the plant; and/or (b) altering expression of a gene encoding a PIRIN4 polypeptide in the plant. A plant with reduced lignin content is produced by increasing expression of a gene encoding a PIRIN2 polypeptide in the plant or decreasing expression of a gene encoding a PIRIN4 polypeptide in the plant. The invention further relates to genetically modified plants produced by the said methods.
