Transcriptomic analysis of cork during seasonal growth highlights regulatory and developmental processes from phellogen to phellem formation [PDF]
Scientific Reports, 2021 The phellogen or cork cambium stem cells that divide periclinally and outwardly specify phellem or cork. Despite the vital importance of phellem in protecting the radially-growing plant organs and wounded tissues, practically only the suberin ...

Potato Periderm Development and Tuber Skin Quality [PDF]
Plants, 2022 The periderm is a corky tissue that replaces the epidermis when the latter is damaged, and is critical for preventing pathogen invasion and water loss. The periderm is formed through the meristematic activity of phellogen cells (cork cambium). The potato

The transcriptome of potato tuber phellogen reveals cellular functions of cork cambium and genes involved in periderm formation and maturation [PDF]
Scientific Reports, 2019 The periderm is a protective corky tissue that is formed through the cambial activity of phellogen cells, when the outer epidermis is damaged. Timely periderm formation is critical to prevent pathogen invasion and water loss.

TheSHORT-ROOT-like genePtSHR2Bis involved inPopulusphellogen activity [PDF]
Journal of Experimental Botany, 2016 SHORT-ROOT (SHR) is a GRAS transcription factor first characterized for its role in the specification of the stem cell niche and radial patterning in Arabidopsis thaliana (At) roots. Three SHR-like genes have been identified in Populus trichocarpa (Pt). PtSHR1 shares high similarity with AtSHR over the entire length of the coding sequence.

Cork Development: What Lies Within [PDF]
Plants, 2022 The cork layer present in all dicotyledonous plant species with radial growth is the result of the phellogen activity, a secondary meristem that produces phellem (cork) to the outside and phelloderm inwards.

The potato suberin feruloyl transferase FHT which accumulates in the phellogen is induced by wounding and regulated by abscisic and salicylic acids [PDF]
Journal of Experimental Botany, 2013 The present study provides new insights on the role of the potato (Solanum tuberosum) suberin feruloyl transferase FHT in native and wound tissues, leading to conclusions about hitherto unknown properties of the phellogen. In agreement with the enzymatic

The first multi-tissue genome-scale metabolic model of a woody plant highlights suberin biosynthesis pathways in Quercus suber. [PDF]
PLoS Computational Biology, 2023 Over the last decade, genome-scale metabolic models have been increasingly used to study plant metabolic behaviour at the tissue and multi-tissue level under different environmental conditions.

Expression analysis of DNA methyltransferase and co-repressor genes in
BMC Proceedings, 2011 Background Cork oak (Quercus suber) is one of the most important forest species in Portugal. Cork oak produces a thick cork bark which is harvested for industrial uses. Cork quality is the most important factor that affects its uses technical performance

Seasonal Dynamics of Periderm Maintenance and Phellogen Re-Initiation in Aesculus hippocastanum
ForestsThe periderm plays a crucial role in trees, acting as a barrier protecting internal tissues against biotic and abiotic stresses, thus having an impact on tree physiology, ecology, and general performance.
