Abstract
Homogeneous groups of cells were excised at regular intervals from opposing (extensor and flexor) motor tissue of S. saman (Jacq) Merrill maintained in white light for 34 h. H+ fluxes between the tissue and bathing solution were then monitored during 30 min of darkness. Flux rates in both cell types vary with circadian rhythms. Flexor cells secrete H+ to the medium during 2/3 of the circadian cycle and take up H+ during the remainder of the cycle, while extensor cells take up H+ from the medium during the entire cycle.This publication has 9 references indexed in Scilit:
