Rhytidome- and cork-type barks of holm oak, cork oak and their hybrids highlight processes leading to cork formation [PDF]
Background The periderm is basic for land plants due to its protective role during radial growth, which is achieved by the polymers deposited in the cell walls.

Translational profile of developing phellem cells in Arabidopsis thaliana roots [PDF]
Summary The phellem is a specialized boundary tissue providing the first line of defense against abiotic and biotic stresses in organs undergoing secondary growth. Phellem cells undergo several differentiation steps, which include cell wall suberization, cell expansion, and programmed cell death.

Anatomical features of the bark as a factor of resistance of fir species to infestation by the four-eyed fir bark beetle [PDF]
To elucidate the reasons for the differences Fir species (Abies. Mill.) damage by four-eyed fir bark beetle (Polygraphus proximus Blandford), we studied the structure of fir bark in sections Balsamea, Momi, Abies, Grandis from the collections of the ...

Atlas of Micromorphological Degradation of Archaeological Birch Bark
In this paper we present an atlas of micromorphological degradation of archaeological birch bark for the first time. We analysed the morphology of 13 samples extracted from ice-logged, waterlogged and cave-retrieved objects dated from the Neolithic to ...

Summary Soybeans (Glycine max) develop newly differentiated aerenchymatous phellem (AP) in response to waterlogging stress. AP is formed in the hypocotyl and root, thus contributing to internal aeration and adaptation to waterlogging for several legumes.

Mechanical cues trigger phellem differentiation during barrier transition
ABSTRACT A continuous and uninterrupted barrier tissue is essential for protecting internal tissues from the external environment. In many dicot roots, the endodermis fulfils this role during primary growth; however, the onset of secondary growth in the vascular tissue coincides with the rupture of the overlying ...

Wood and bark of Buddleja: uniseriate phellem, and systematic and ecological patterns
Abstract Wood anatomy of Buddleja is well-explored but not in many southern African members, which form a grade of species and small clades that form successive sister groups to the rest of the genus, and its bark structure has not been studied at all.
