Summary We analyze the oldest fossil occurrences of wound‐response periderm to characterize the development of wound responses in early tracheophytes. The origin of periderm production by a cambium (phellogen), an innovation with key roles in protection of inner plant tissues, is poorly explored; understanding periderm development in early ...

Botanical Gazette, 1975
Initiation of first and successive phellogens occurs mostly in phloem parenchyma or in its derivatives. Species in which shoot phellogen is initiated in the epidermis are the exceptions. However, even in such species, root phellogen is formed in the pericycle.

Ontogeny of Periderm and Phellogen Activity in Ceratonia siliqua L.
Botanical Gazette, 1977In the shoots of Ceratonia siliqua, except for the hypocotyl and the first internode, a continuous superficial phellogen and complete cork cover are established only after a prolonged period of growth has elapsed. The initiation of sequent periderms is restricted to tree parts estimated to be more than 40 yr old.

Transcriptional profiling of cork oak phellogenic cells isolated by laser microdissection
Planta, 2017The phenylpropanoid pathway impacts the cork quality development. In cork of bad quality, the flavonoid route is favored, whereas in good quality, cork lignin and suberin production prevails. Cork oaks develop a thick cork tissue as a protective shield that results of the continuous activity of a secondary meristem, the cork cambium, or phellogen. Most

Formation of the primary protective layer and phellogen after leaf abscission in peach
Canadian Journal of Botany, 1985Potted peach trees (Prunus persica (L.) Batsch cv. Loring) were mechanically defoliated and the influence of temperature on formation of the primary protective layer and phellogen generation in the leaf abscission region was examined histologically.

An Endodermal Phellogen in the Stem of Paederia foetida Linn
Nature, 1945DURING the course of an anatomical study of Pœderia fœtida, a twining shrub of these parts, belonging to the family Rubiaceae, we found that the phellogen originates in the stem, not in the subepidermal layers of the cortex as in most dicotyledons, but in the endodermis.

American Journal of Potato Research, 2002
The susceptibility of potato tubers to excoriation (idiom = skinning injury) during harvest is a widespread problem that results in costly disease, defects, and shrinkage. Little is known about the physiology associated with susceptibility of immature periderm and the development of full and final resistance to skinning injury (skin-set) upon periderm ...

Sites of First Phellogen Initiation in Conifers
IAWA Journal, 1989Sites of first phellogen initiation were studied in ten species of Pinaceae and Cupressaceae. The distance from the apex, age and the tissue from which the first phellogen is initiated, were determined. In Pinaceae the first phellogen arises at a shorter distance from the apex than in Cupressaceae.

Phellogen initiation in the stems of Eucalyptus camaldulensis Dehnh
Australian Journal of Botany, 1970The induction of phellogen in E. camaldulensis stems by various environmental factors was investigated. High humidity and a continuous flush of oxygen were found to cause early initiation of the phellogen. Light, temperature changes, or mechanical pressure did not play an important role in the initiation of phellogen as long as they ...
