Abstract
A peanut mutant with 72.53% oleate content was selected from sodium azide mutagenized peanut Huayu 22, an export type cultivar with 51.65% oleate content. The chemical mutant had a point mutation (C281T) in the coding region of FAD2B, which caused a T94I substitution in the FAD2B protein. Though the mutated FAD2B gene was incompletely dysfunctional as shown in yeast expression system, the peanut mutant has a high oleic acid phenotype. This indicated the possible involvement of other unidentified genetic factor(s) conditioning oleic acid content in peanut.
