The dermatogen forms the epidermis. The periblem gives rise to the cortex and
the plerome forms the central cylinder comprising stele and pith. A fourth
histogen called calyptrogen is also identified which forms the root cap.

The Molecular Biology of Plant Development
Within the meristem cells grow at different rates depending on their location : for
instance, in Zea the calyptrogen has the fastest cell growth rate, the quiescent
centre has the slowest. In all regions of the meristem the period from the start of S

The Plant Cell Cycle and Its Interfaces
The calyptrogen/dermatogen complex was later named as the tier related by
lineage to the root cap and the epidermis (Cutter, 1971). In the interests of
simplicity, we propose the use of the English equivalents for each of these terms
as follows ...

There is a definite plerome and periblem and a common initiating zone for the
root cap and epidermis, the dermatogen-calyptrogen layer. I'enzig (l.!f). in

Plant Structure, Second Edition
In some plants such as Zea mays, the root cap has its own distinct initials (
calyptrogen, 248). The incipient epidermis (protoderm) and cortex can be traced
to a single tier of cells adjacent to the calyptrogen, while the central procambial
cylinder ...

Question Bank In Biology For Class Xi
In roots, the cells of the dermatogen form a mass of small tissue called
calyptrogen. The calyptrogen is also meristematic and gives rise to the root cap.
In dicotyledonous plants, the dermatogen forms the outermost layer (epiblema) of
the root.
