Kinetin meristems

In tomato root meristems, auxin causes an increase in the number of longitudinal and a decrease in the number of transverse divisions (Hughs and Street 1960), while in intercalary meristem segments from Avena stems, kinetin enhances transverse cell division and causes a shift of division within the intercalary meristem from the transverse to the longitudinal direction (Jones and Kaufman 1971). These effects were obtained only with high levels of kinetin.
