1. A pennycress plant having reduced levels of polyunsaturated fatty acids (PUFAs) and/or increased levels of oleic acid, said pennycress plant comprising:
a genome comprising a modified reduced oleate desaturation 1 (ROD1) gene, wherein the modified ROD1 gene comprises a loss-of-function modification effective to knock-out expression levels of ROD1 polypeptides and/or ROD1 polypeptide activity;
wherein an unmodified coding sequence of the ROD1 gene encodes a ROD1 polypeptide having the amino acid sequence shown in SEQ ID NO:10; and
wherein the modification in the ROD1 gene is effective to reduce levels of PUFAs and/or increase levels of oleic acid in the plant compared to a corresponding pennycress plant lacking the modification in the ROD1 gene.
