Temporal and spatial expression of oleate desaturase gene with different O/L values in peanut varieties

Four different O/L(oleate acide/linoleic acid) peanut varieties were selected to analyze the relative quantitative expression of FAD2 gene in the different tissues by real-time fluorescence quantitative PCR technology.Results showed that FAD2 gene in different O/L genotypes presented constitutive expression.The expressions of the FAD2 gene were lower in the root,stem and leaf tissues.The expression in the flowers was significantly higher than that in pod and other tissues,and the difference among varieties was significant;The expression of HuaU606 and HuaU12 in flowers,young pods and mature pods tissues declined successively,and the expression of Huayu17 and Shiyouhong 4 showed high-low-high expression trends,the difference reached significant level.
