Growth trends reveal the forest structure during Roman and Medieval times in Western Europe: a comparison between archaeological and actual oak ring series (Quercus robur and Quercus petraea) [PDF]

open access: yes, 2005
At some point in time, man has influenced nearly all forests in Western Europe. Most of the original forest cover has been converted to arable land and pastures, or has been cut for the supply of firewood and construction timber.

Composition, distribution and supposed origin of mineral inclusions in sessile oak wood - consequences for microdensitometrical analysis [PDF]

open access: yes, 2007
SEM and light-microscopical observations, supported by chemical microanalysis with an EDXA system, revealed that light-saturated pixels observed in X-ray negatives of sessile oak (Quercus petraea Liebl.) wood were caused by inorganic deposits present ...

The formation of heterogeneous storeys in the cambium on the example of Laburnum anagyroides Medik

open access: yesActa Agrobotanica, 2012
The formation of the storeyed pattern of cambium in the first two years of cambial activity and the structure of mature cambium was examined in Laburnum anagyroides, a decorative shrub growing in temperate climate.

ACAULIS5 Is Required for Cytokinin Accumulation and Function During Secondary Growth of Populus Trees

open access: yesFrontiers in Plant Science, 2020
In the primary root and young hypocotyl of Arabidopsis, ACAULIS5 promotes translation of SUPPRESSOR OF ACAULIS51 (SAC51) and thereby inhibits cytokinin biosynthesis and vascular cell division.

CAMBIAL ACTIVITY IN EUCALYPTUS CAMALDULENSIS DEHN. [PDF]

open access: yesNew Phytologist, 1966
SummaryThe production of xylem and phloem elements by the cambium of Eucalyptus camaldudensis was investigated. Plants grown under various climatic treatments were exposed to 14CO2 for short periods. This treatment left a marker in the xylem and in the phloem cells derived from the cambium during the exposure.

Timing of cambial phenology of rainforest trees as indicator of climate sensitivity of the Congo Basin biome

open access: yesGlobal Ecology and Conservation
The tropical forests of the Congo Basin biome are particularly diverse. The question arises whether the cambial activity of the multitude of tree species shows a periodic signal. Given the anticipated increases in temperature and changes in precipitation

Transcriptome characteristics and six alternative expressed genes positively correlated with the phase transition of annual cambial activities in Chinese Fir (Cunninghamia lanceolata (Lamb.) Hook). [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: The molecular mechanisms that govern cambial activity in angiosperms are well established, but little is known about these molecular mechanisms in gymnosperms.

CYCD3 D-type cyclins regulate cambial cell proliferation and secondary growth inArabidopsis [PDF]

open access: yes, 2015
A major proportion of plant biomass is derived from the activity of the cambium, a lateral meristem responsible for vascular tissue formation and radial organ enlargement in a process termed secondary growth.

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

open access: yesCell 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.
