Cytological events during the initiation of meristematic nodules in calli derived from eggplant protoplasts.
Histological and ultrastructural studies have been undertaken in order to identify the particularities and, if possible, some mechanisms involved in regeneration from protoplasts in the eggplant Solanum melongena. The most important result consists of a peculiar and concomitant association of meristematic and differentiated features only in cells from which regenerative processes originate.
