SYZ conjecture on mirrors of Lagrangian sections

Let $M \to B$ and $\check{M} \to B$ be dual torus fibrations arising in the SYZ picture, and let a Lagrangian section of $M \to B$ be a Lagrangian submanifold mapping isomorphically to $B$. Its mirror is an object on $\check{M}$, and a holomorphic line bundle is a line bundle equipped with a holomorphic structure. SYZ section-to-line-bundle conjecture. The mirror of a Lagrangian section of $M \to B$ is a holomorphic line bundle on $\check{M}$. This is described in the paper as a folkloric observation and is the part of the SYZ intuition used for toric varieties; the supplied text gives no resolution status.
