Characterization of hemicellulose in Cunninghamia lanceolata stem during xylogenesis

International Journal of Biological Macromolecules, 2023
In this study, hemicellulose was isolated from the apical, middle and basal segments of C. lanceolata stem to investigate the dynamic change of its structure during xylogenesis. Results showed that the C. lanceolata hemicellulose is mainly consisted of O-acetylgalactoglucomannan (GGM) which backbone is alternately linked by β-d-mannopyranosyl (Manp ...

Characterization of hemicellulose during xylogenesis in rare tree species Castanopsis hystrix

International Journal of Biological Macromolecules, 2022
Hemicellulose is an important component of the plant cell wall which vary in structure and composition between plant species. The research of hemicellulose structures is primarily focused on fast-growing plants during xylogenesis, with slow-growing and rare trees receiving the least attention.

Xylogenesis: the birth of a corpse

Current Opinion in Plant Biology, 2000
Xylogenesis 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 ...

Cell-wall fluorescence highlights the phases of xylogenesis

IAWA Journal, 2021
Summary 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.

Plastic responses of Abies pinsapo xylogenesis to drought and competition [PDF]

Tree Physiology, 2009
Radial growth and xylogenesis were studied to investigate the influence of climate variability and intraspecific competition on secondary growth in Abies pinsapo Boiss., a relic Mediterranean fir. We monitored the responses to three thinning treatments (unthinned control -C-, 30% -T30- and 60% -T60- of basal area removed) to test the hypothesis that ...

Programming of cell death during xylogenesis

Journal of Plant Research, 1998
Death 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

Cadmium induces premature xylogenesis in barley roots

Plant and Soil, 2006
The 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.

Characterization of hemicelluloses from Neolamarckia cadamba (Rubiaceae) during xylogenesis

Carbohydrate Polymers, 2017
In this study, hemicelluloses were isolated from the apical, middle and basal segments of N. cadamba using a 2N KOH extraction procedure. Chemical composition and structural characterization of the three hemicellulosic fractions obtained were comparatively investigated by a combination of HPLC, GPC, FTIR, 1H,13C, HSQC NMR and TGA techniques.

INDUCTION OF XYLOGENESIS IN PITH PARENCHYMA EXPLANTS OF LACTUCA

American Journal of Botany, 1971
Explants 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.
