(Submitter supplied) The phellogen or cork cambium is a bifacial stem cell population from which derivatives are formed by periclinal divisions and specified on opposing sides as phelloderm (inwardly) and phellem or cork (outwardly). Altogether the three layers constitute the periderm which covers and protects the radially-grown organs (stems, roots and tubers) and wounded tissues from dehydration and pathogen attack. The phellem is the final responsible of the protective function of periderm and despite its vital importance, just the suberin biosynthetic process has been studied molecularly while other processes are poorly understood. more...

(Submitter supplied) The periderm of trees produces cork cells, whose cell walls are modified with suberin. We compared the transcriptome of outer bark (cork) vs inner bark (control containing secondary phloem and vacular meristem) to infer genes related to suberim metabolism.

(Submitter supplied) 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. Despite the research on the topic has unravelled the role of several enzymes and transcription factors, many questions remain open, especially those regarding cell development. Here we use the outer bark of cork oak (cork), holm oak (rhytidome), and their natural hybrids’ to further understand the mechanisms underlying periderm development. more...

(Submitter supplied) Russeting is a commercially important defect in apple (Malus x domestica) fruit production. Apple russeting is mainly characterized by the accumulation of suberin on the inner part of the cell wall. However, knowledge on the underlying genetic components triggering this trait remains sketchy. A bulk transcriptomic profiling was performed on the exocarps of three russeted and three waxy apple varieties using RNA sequencing. more...

(Submitter supplied) Internal aeration is crucial for root growth in waterlogged soil. A barrier to radial oxygen loss (ROL) can enhance long- distance oxygen transport via the aerenchyma to the root tip; a higher oxygen concentration at the apex enables root growth into anoxic soil. The ROL barrier is formed within the outer part of roots (OPR). Suberin and/or lignin depos- ited in cell walls are thought to contribute to the barrier, but it is unclear which compound is the main constituent. more...
