Time-variable frequency of events in domains of Tilia cambium

open access: yesActa Societatis Botanicorum Poloniae, 2014
In the cambium of linden, producing xylem with interlocked grain, domains active, as regards the occurrence of events, and inactive ones can be distinguished.

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

open access: yesNew Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Perception of gravity expressed by production of cambial callus in ash (Fraxinus excelsior L) internodes

open access: yesActa Societatis Botanicorum Poloniae, 2011
In ash internodes isolated from vertical stems during winter dormancy, cambial activity was stimulated by applying an aqueous solution of auxin to the apical end and water to the basal end.

Plant Peptides on the Rise: From Historical Insight to Future Applications

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

Seasonal changes in the degree of symplasmic continuity between the cells of cambial region of Acer pseudoplatanus and Ulmus minor

open access: yesActa Societatis Botanicorum Poloniae, 2011
The presence of symplasmic isolation and symplasmic continuity which are functional aspects of cell-to-cell communication, had been studied in cambium of Acer pseudoplatanus and Ulmus minor, with hope that uniqueness of this meristem, exemplified by its ...

Spatiotemporal Metabolome and Single‐Nucleus Transcriptome Integration Illuminates an Auxin Gradient Orchestrated by NtTAC1 Underlying Leaf Angle Regulation in Tobacco

open access: yesPlant Biotechnology Journal, EarlyView.
Proposed model of TAC1‐mediated leaf angle regulation in tobacco. ABSTRACT Plant architecture is key to crop yield, with leaf angle being critical for high‐density cultivation. Although TAC1 represents a promising regulator of leaf angle for breeding, its molecular mechanism remains poorly understood, particularly at single‐nucleus resolution. Here, we

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

A five-year dendrometer record in two trees of Pinus strobus [PDF]

open access: yes, 1947
So far as is known to us there is no published account of a dendrometer record of white pine growth behavior. Brown (2) studied growth behavior and cambial activity using the histological method; Goldthwait and Lyon (5) studied secondary growth in ...

Sampling cambial region and mature xylem for non structural carbohydrates and starch analyses [PDF]

open access: yes, 2011
This paper describes a procedure to analyze non-structural carbohydrates (NSC) and starch in xylem and cambial region extracted by the scraping method. An application on woody logs of 2-year-old Populus×canadensis Mönch 'I-214' during tree-ring formation
