Environmental Drivers for Cambial Reactivation of Qilian Junipers (Juniperus przewalskii) in a Semi-Arid Region of Northwestern China

open access: yesAtmosphere, 2020
Although cambial reactivation is considered to be strongly dependent on temperature, the importance of water availability at the onset of xylogenesis in semi-arid regions still lacks sufficient evidences.

Activation of Cambial Growth by Pure Hormones [PDF]

open access: yesNature, 1935
IN a recent letter to NATURE1 it was reported that strong cambial growth can be activated in young decapitated sun-flower seedlings by inserting their upper ends into tubes containing a weak solution in gelatine of the ether-soluble component of urine. With a similar method it has now been found that strong cambial growth can be activated by solutions ...

Seasonal cambial activity of some mangrove trees in Inner Gulf of Thailand in dependence on climate [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2012
This study aims to investigate the relationship between the cambial activity of Rhizophora mucronata, Avicenniaalba, and Avicennia marina and climatic factors (e.g., rainfall, temperature, salinity, and sea water level) in Samut SakhonProvince, Thailand.

Spatial specificity of auxin responses coordinates wood formation

open access: yesNature Communications, 2018
Auxin activity controls plant stem cell function. Here the authors show that in the cambium, moderate auxin activity restricts cambial stem cell number via ARF5-dependent repression of the stem‐cell‐promoting factor WOX4, while ARF3 and ARF4 promote ...

A molecular timetable for apical bud formation and dormancy induction in poplar [PDF]

open access: yes, 2007
The growth of perennial plants in the temperate zone alternates with periods of dormancy that are typically initiated during bud development in autumn. In a systems biology approach to unravel the underlying molecular program of apical bud development in

Overexpression of a Prefoldin β subunit gene reduces biomass recalcitrance in the bioenergy crop Populus. [PDF]

open access: yes, 2020
Prefoldin (PFD) is a group II chaperonin that is ubiquitously present in the eukaryotic kingdom. Six subunits (PFD1-6) form a jellyfish-like heterohexameric PFD complex and function in protein folding and cytoskeleton organization.

Effect of plant hormones on the cambial activity of Cerasus vulgaris Miller under stress conditions with Zn

open access: yesJournal of Plant Protection Research, 2019
In the present study, the effects of 10, 20, 30 ppm hormone mixtures (indole-3-acetic acid + + gibberellic acid + kinetin) with 0.1, 0.3, 0.5 and 1 ppm zinc (Zn) concentrations alone and their mixtures on the cambial activity of sour cherry (Cerasus ...

Intra-annual dynamics of cambial and xylem phenology in subalpine conifers at Deogyusan National Park in the Republic of Korea

open access: yesJournal of Wood Science, 2021
Subalpine conifers are highly sensitive to climatic changes. In these trees, the intra-annual dynamics of cambial activity and phenological process in xylem development are closely associated with climatic conditions.
