2.A.1.19.13
The organic cation transporter, Oct1 (transports L-carnitine; expressed in vascular tissues of various organs and at sites of lateral root formation) (Lelandais-Briere et al, 2007). It also transports spermine and other polyamines and is induced by them (Sagor et al. 2016).  It protects against the polyamine, cadaverine, which affects root length (Strohm et al. 2015).
