Received 10 September 1999; revised manuscript received 11 September 2000
Accepted 18 September 2000

It is discussed how various Ansätze for the dressed quark-photon (qqg) vertices Gm(q,q˘) influence the asymptotics of the g* p0 transition form factor. In this regard, we rectify certain misconceptions present in the literature.
