The tribe Bignonieae includes all Neotropical lianescent Bignoniaceae. The leaves of
Bignonieae are generally 2-or 3-foliolate, with terminal leaflets modified into a tendril. These
tendrils have varied morphologies and are thought to have been involved in the
diversification of Bignonieae. Little, however, is still known about the biology and evolution
of tendrils. This study investigated the evolution and development of tendril types in
Bignonieae in order to further understand how changes in leaf morphogenesis led to current …
