Regulates Vegetative Growth, Pathogenicity and Linoleic Acid Biosynthesis in .

Polyunsaturated fatty acids (PUFAs), as important components of lipids, play indispensable roles in the development of all organisms. ∆12 fatty acid desaturase () is a speed-determining step in the biosynthesis of PUFAs. Here, we report the characterization of in which is the prevalent agent of Fusarium head blight, a destructive plant disease worldwide.
