The fate of surface cell layers of Daucus carota (L.) embryos raised in suspension culture

Listed in DataCite

The ultrastructure and fate of surface cells covering mature somatic embryos of Daucus carota grown in suspension culture were analyzed and new information obtained concerning somatic embryogenesis in these conditions.

Description

Our studies showed that, during some developmental stages, these embryos were covered irregularly and discontinuously by cells with a typical protodermal phenotype characterized by a cuticle on the outer cell wall.

We observed that cells with cuticle were peeled off from the surface of mature embryos. Before peeling off, these cells underwent programmed cell death (PCD), which was confirmed by the TUNEL method. Transmission electron microscopy revealed advanced processes of autophagy in these cells.
