To make the cake, preheat the oven to 350˚ F. Grease and flour a 9 x 5-inch loaf pan. In a medium bowl, combine the flours, baking powder, baking soda and salt. Whisk to blend and set aside. In the bowl of an electric mixer, combine the sugar, eggs, lemon zest and lemon juice. With the mixer on low speed, blend in the melted butter. On low speed, mix in half of the dry ingredients just until incorporated. Beat in the sour cream and vanilla until combined. Mix in the remaining dry ingredients, again just until incorporated.

Transfer the batter to the prepared pan. Bake 20 minutes, then rotate the pan and reduce the oven temperature to 325˚ F. Continue baking 30-35 minutes or until a toothpick inserted in the center comes out clean. Let cool in the pan at least 15-20 minutes.

Turn the cake out of the pan and transfer to a wire rack set over a baking sheet. To make the lemon syrup, combine the sugar and lemon juice in a small saucepan over medium heat, cooking just until the sugar is completely dissolved. Poke the top of the warm cake all over with a toothpick or skewer and pour the lemon syrup over the top.
