  It is reported on predictions for the $\pi$-$\gamma$ transition form factor
obtained within a perturbative approach which includes transverse momentum
effects and Sudakov corrections. The results clearly favor distribution
amplitudes close to the asymptotic form, $\sim x_1x_2$, and disfavor
distribution amplitudes which are strongly concentrated in the end-point
regions. Applications of that approach to the $\eta$-$\gamma$ and
$\eta^\prime$-$\gamma$ transition form factors are discussed as well.
