Abstract

1‐Methyladenine, which induces meiosis reinitiation in starfish oocytes, stimulates ^32^P incorporation into proteins and activates the ouabain‐sensitive Rb^+^ influx in anucleated fragments obtained from full‐grown Marthasterias glacialis oocytes. This shows that hormone‐induced stimulation of protein phosphorylation and Na^+^ pump does not require the presence of the nucleus. Stimulation of protein phosphorylation is, however, delayed and reduced with respect to intact oocytes.

Cell-wall acidification and electrical reactions (depolarization and hyperpolarization) are typical auxin responses in maize (Zea mays L.) coleoptiles. In an attempt to test the role of the outer epidermis in these responses, they have been measured and compared in intact and peeled coleoptile fragm
