In cell walls of phellem of potato tubers (Solanum tuberosum cv Bintje) a yellow autofluorescence was observed when viewed with blue light (470–490 nm). A similar autofluorescence was also observed in tuber tracheary elements, suggesting that the fluorescence is caused by lignin or lignin-like material.

Anatomy and Development of the Endodermis and Phellem ofQuercus suberL. Roots
Microscopy and Microanalysis, 2013AbstractQuercus suberL. has been investigated with special attention to the stem bark and its cork formation layer, but excluding the roots. Roots are the location of infection by pathogens such asPhytophthora cinnamomiresponsible for the tree's sudden death.

Abstract Quercus suber (cork oak) is a sustainably exploited forest resource, producing a unique renewable raw material known as cork. With drought events imposing a negative impact on tree vitality, we need more knowledge on the genetic and environmental regulation of cork development to protect the

Water and oxygen permeance of phellems isolated from trees: the role of waxes and lenticels
Planta, 2002The outermost phellems of Abies alba Mill., Acer pseudoplatanus L., Aesculus hippocastanum L., Betula potaninii L.C. Hue and Sambucus nigra L. have been isolated enzymatically, resulting in membranes with five to seven heavily suberized cork cell layers. Water and oxygen permeances were determined for the phellem areas without lenticels.

Occurrence of Atypical Phellem in Representatives of Cornus
International Journal of Plant Sciences, 2014Premise of research. Epidermis and periderm protect internal plant tissues against environmental factors, water loses, and pathogen entry. Formation of periderm, which replaces epidermis in ontogeny, is generally known; however, the mechanisms involved in this process, as well as the deposition of cutin and suberin in the cell walls of protective ...

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 ...

Attractive appearance is highly desirable for fresh market red-skinned potatoes. Red potatoes derive their skin color from anthocyanins. Some growers attempt to enhance red potato skin color by treating vines with the synthetic auxin 2,4-D. In this study, 2,4-D was applied twice at early bloom stage to ‘Red Norland’ potatoes and tubers were harvested ...

Role of MYB Transcription Factors During Phellem Differentiation
The periderm is a crucial protective barrier that plays a vital role in secondary growth. It is a multi-layered tissue composed anatomically of three layers: the phellem or cork, the phellogen or cork cambium, and the phelloderm. The phellogen, a meristematic layer, undergoes bifacial divisions, generating the phellem outward and the phelloderm inward.openaire +3 more sources
