A miR156-SPL module controls shade-induced inhibition of vascular cambium activity through cytokinin pathway in poplar

Cell Reports
Summary: In natural forests and plantations, trees often encounter neighbor proximity that hinders wood production. However, the mechanisms by which shade regulates cambial activity during secondary growth remain elusive.

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.

The effect of stem girdling on xylem and phloem formation in Scots pine

Silva Fennica, 2017
Scots pine ( L.) is a resilient, wide spread species. This paper reports on the xylem and phloem cell formation process, before and after, the species was put under artificial stress by stem girdling.

Cambial growth season of brevi-deciduous Brachystegia spiciformis trees from south central Africa restricted to less than four months. [PDF]

PLoS ONE, 2012
We investigate cambial growth periodicity in Brachystegia spiciformis, a dominant tree species in the seasonally dry miombo woodland of southern Africa. To better understand how the brevi-deciduous (experiencing a short, drought-induced leaf fall period)

Endogenous oscillations of electric potential difference in the cambial region of the pine stem. I. General characteristics of the oscillations

Acta Societatis Botanicorum Poloniae, 2014
Extracellular measurements of electric potential difference (PD) in isolated tissue blocks from Scots pine were performed. Endogenous transient PD changes (oscillations) generated exclusively in the cambial region were found.

Collagen‐membrane‐covered matrix‐associated chondrocyte implantation improves safety over periosteum‐covered MACI for large knee cartilage defects: A real‐world data analysis in the registry study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This registry study aimed to evaluate the safety and effectiveness of collagen membrane‐covered matrix‐associated autologous chondrocyte implantation (cMACI) versus periosteum‐covered MACI (pMACI) for large knee cartilage defects (Outerbridge III–IV, ≥4 cm²) in the femorotibial and/or patellofemoral joints with a minimum 2‐year follow ...

Seasonal variation of auxin in stem cambial region of Pinus sihestris L.

Acta Societatis Botanicorum Poloniae, 2015
Investigation of auxin from the stem cambial region of adult Pinus silvestris trees by diffusion to agar, and by extraction revealed both seasonal variation and gradients along the stem. Variation in dynamics of auxin efflux and the effect of the size of

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Radial growing, cambial activity, and phenology of tree species in a subtropical forest in Southern Brazil

iForest - Biogeosciences and Forestry
Understanding the factors that affect cambial activity can provide historical documentation of events influencing plant growth and development. This study aimed to link cambial activity and diameter increment of native and exotic species in a floodplain ...

Divergent shifts in hydraulic versus carbon acquisition functional traits after wildfire in four Rocky Mountain tree species

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change has increased the frequency and severity of drought and large wildfire events across western North America. Despite the increasing concurrence of drought and wildfire events and the importance of forests as a global carbon sink, the impacts of fire on ...
