Contrasting nitrogen fertilization treatments impact xylem gene expression and secondary cell wall lignification in Eucalyptus [PDF]

, 2014
BackgroundNitrogen (N) is a main nutrient required for tree growth and biomass accumulation. In this study, we analyzed the effects of contrasting nitrogen fertilization treatments on the phenotypes of fast growing Eucalyptus hybrids (E.

Mechanisms of Cell-wall Growth in Secondary XYLEM [PDF]

, 2007
Current concepts of the growth of the cell wall in secondary xylem are briefly reviewed. Following a description of the organization of the mature cell wall, its development is traced from initiation in the cambial zone to maturity.

Proteolytic activity in the stem cambial region of Pinus sylvestris L. - A contribution to the specific differentiation of secondary xylem and phloem

Acta Societatis Botanicorum Poloniae, 2014
Proteolytic activity was studied in the differentiating xylem and phloem of Scots pine (Pinus sylvestris L.) to determine the specificity of xylem and phloem differentiation.

Flowering as a Condition for Xylem Expansion in Arabidopsis Hypocotyl and Root [PDF]

, 2008
SummaryIn dicotyledons, biomass predominantly represents cell-wall material of xylem, which is formed during the genetically poorly characterized secondary growth of the vasculature.

The ASYMMETRIC LEAVES1 ortholog PagAS1a promotes xylem development and plant growth in Populus

Forestry Research
ASYMMETRIC LEAVES1 (AS1) is a central regulator of leaf polarity establishment in Arabidopsis. However, the functions of its ortholog genes in Populus are unclear.

Differences in the Structural Chemical Composition of the Primary Xylem of Cactaceae: A Topochemical Perspective

Frontiers in Plant Science, 2019
The xylem of Cactaceae is a complex system with different types of cells whose main function is to conduct and store water, mostly during the development of primary xylem, which has vessel elements and wide-band tracheids. The anatomy of primary xylem of

Osmotic potential of Zinnia elegans plant material affects the yield and morphology of tracheary elements produced in vitro [PDF]

, 2010
The Zinnia elegans cell suspension culture is excellent for xylogenesis studies at the cellular and molecular level, due to the high and synchronous in vitro differentiation of tracheary elements (TEs).

xylem specification through the prevention of premature cell death [PDF]

, 2008
Cell size and secondary cell wall patterning are crucial for the proper functioning of xylem vessel elements in the vascular tissues of plants. Through detailed anatomical characterization of Arabidopsis thaliana hypocotyls, we observed that mutations in

Biological basis of tree-ring formation: a crash course

Frontiers in Plant Science, 2016
Wood is of crucial importance for man and biosphere. In this mini review, we present the fundamental processes involved in tree-ring formation and intra-annual dynamics of cambial activity, along with the influences of the environmental factors.
