The formation of secondary plasmodesmata was analyzed inSolanum nigrum L. protoplast cultures. Half and continuous secondary plasmodesmata were present in dedifferentiated, regenerating cells. The observed precursor stages confirm a recent, novel explanation for the establishment of secondary plasmodesmata. It is proposed that secondary plasmodesmata are formed after a process of membrane and vesicle fusion, with unexpected similarities to the common model for primary plasmodesmata formation during cell division.
