Meaning and Definition

A layer of cells in a plant, such as a root tip or shoot apex, from which specific tissues develop.

In botany, a term for any distinct meristematic cell layer responsible for generating specific mature plant tissues (e.g., dermatogen, periblem, plerome). It can also refer more broadly to a region or group of cells with a specific developmental fate in an organism.

It acts as a source of cells that will differentiate into one or more specific mature tissues in a plant.

Yes, the related adjective is 'histogenic'. The concept is central to the 'histogen theory' of plant development.
