Xylogenesis: the birth of a corpse
Current Opinion in Plant Biology, 2000Xylogenesis is a complex developmental process culminating in programmed cell death as a truly terminal differentiation event. In Arabidopsis, the availability of vascular-patterning mutants, and the identification of genes and their products that are involved in cell specification, secondary-wall deposition and lignification, are providing clues to ...

INDUCTION OF XYLOGENESIS IN PITH PARENCHYMA EXPLANTS OF LACTUCA
American Journal of Botany, 1971Explants of pith parenchyma excised from Romaine lettuce heads (Lactuca sativa Linn. var. Romàna) exhibited xylogenesis after four days dark incubation on a Murashige and Skoog (1962) medium containing auxin (IAA, NAA, or 2,4‐D), cytokinin (zeatin, kinetin, or benzyladenine), sucrose, and agar.

Cell-wall fluorescence highlights the phases of xylogenesis
IAWA Journal, 2021Summary The monitoring of xylogenesis makes it possible to follow tree growth responses to stress factors in real-time, by observing the course of wood cell division and differentiation. Proper microscopy techniques are of key importance to exactly identify the xylem cells during the different phases of differentiation.

Duration of xylogenesis in black spruce lengthened between 1950 and 2010 [PDF]
Annals of Botany, 2012 Reconstructions have identified the 20th century as being uniquely warm in the last 1000 years. Changes in the phenology of primary meristems converged toward increases in length of the growing season. Has the phenology of secondary meristem changed during the last century, and to what extent?Timings of wood formation in black spruce, Picea mariana ...

Cadmium induces premature xylogenesis in barley roots
Plant and Soil, 2006The effect of Cd on H2O2 production, peroxidase (POD) activity and root hair formation were analyzed in barley root. Cd causes a strong H2O2 burst in the root region 0–6 mm behind the root tip. POD activity was activated in root tip and raised toward the root base in Cd treated roots.

Plant Biosystems, 2008 Long-sized oligogalacturonides (OGs) are plant cell wall fragments involved in defence responses and developmental processes. A hormone/OG interaction in the control of different organogenic processes is known.

Programming of cell death during xylogenesis
Journal of Plant Research, 1998Death of tracheary elements which compose vessels and tracheids is a typical example of programmed cell death in plants. Anin vitro system usingZinnia mesophyll cells which differentiate directly into tracheary elements has provided various types of data on the cell death process. In this paper, we will summarize recent results obtained using theZinnia

Xylogenesis in zinnia (Zinnia elegans) cell cultures: unravelling the regulatory steps in a complex developmental programmed cell death event [PDF]
Planta, 2017 Main conclusion: Physiological and molecular studies support the view that xylogenesis can largely be determined as a specific form of vacuolar programmed cell death (PCD).

XYLOGENESIS: INITIATION, PROGRESSION, AND CELL DEATH
Annual Review of Plant Physiology and Plant Molecular Biology, 1996▪ Abstract Xylem cells develop from procambial or cambial initials in situ, and they can also be induced from parenchyma cells by wound stress and/or a combination of phytohormones in vitro. Recent molecular and biochemical studies have identified some of the genes and proteins involved in xylem differentiation, which have led to an understanding of ...
