AB - Abstract Leaf slices of oats were loaded with 14C-flamprop ((1)–2(N-Benzoyl-3-chloro-4-fluoranilino) propionic acid) for 24 h. At this time, extensive metabolism to polar conjugates had occurred. Compartmental analysis was carried out and the composition of radioactivity in each of the efflux compartments was determined. Efflux of total radioactivity was described by three kinetically distinct transport phases of cellular origin. Flamprop itself was present in three pools, two of which were readily removed by washing the slices in buffer. The third pool was only released by extraction with an organic solvent. The efflux of flamprop conjugates followed a completely different pattern. They were only very slowly removed by the washing procedure, demonstrating that conjugation has a marked effect on mobility. One group of conjugates could be almost completely washed from the tissue following disruption of cellular membranes by a freeze/thaw procedure, indicating that immobility of this group was due to partition behind an impermeable membrane. The other group of conjugates could be only partially removed by this procedure, the remainder being released by extraction with an organic solvent.
