Evidence of threshold temperatures for xylogenesis in conifers at high altitudes

Oecologia, 2006
Temperature is the most important factor affecting growth at high altitudes. As trees use much of the allocated carbon gained from photosynthesis to produce branches and stems, information on the timing and dynamics of secondary wood growth is crucial to assessing temperature thresholds for xylogenesis.

The Role of DNA Methylation in Xylogenesis in Different Tissues of Poplar [PDF]

Frontiers in Plant Science, 2016
In trees, xylem tissues play a key role in the formation of woody tissues, which have important uses for pulp and timber production; also DNA methylation plays an important part in gene regulation during xylogenesis in trees.

Causes and correlations in cambium phenology: towards an integrated framework of xylogenesis [PDF]

Journal of Experimental Botany, 2011
Although habitually considered as a whole, xylogenesis is a complex process of division and maturation of a pool of cells where the relationship between the phenological phases generating such a growth pattern remains essentially unknown. This study investigated the causal relationships in cambium phenology of black spruce [Picea mariana (Mill.) BSP ...

Temporal scale of the action of temperature and photoperiod on the xylogenesis at the treeline

Forest@, 2007
The possible role and interaction of two ecological factors, photoperiod and temperature, on xylogenesis of conifers growing at treeline are review. In cold climates, temperature is one of the major factors regulating metabolic activities of plants and ...

Tree Growth Under Climate Change: Evidence From Xylogenesis Timings and Kinetics

Frontiers in Plant Science, 2020
Tree growth is one of the most studied aspects of tree biology, particularly secondary growth. In the Mediterranean region, cambial activity is mostly determined by water availability.

Asynchronous and correlations of radial growth between different lateral meristems in Abies forrestii var. smithii [PDF]

BMC Plant Biology
Understanding radial growth phenology is crucial in the comprehension of tree physiology and its susceptibility to climate change. Numerous studies have investigated the impacts of radial growth activity in stem meristems and environmental factors on ...

Tree-ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring. [PDF]

New Phytol
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 ...

Long-Term Cambial Phenology Reveals Diverging Growth Responses of Two Tree Species in a Mixed Forest Under Climate Change. [PDF]

Glob Chang Biol
We studied how climate change affects tree growth by monitoring wood formation in Scots pine (Pinus sylvestris) and Pyrenean oak (Quercus pyrenaica) over 11 years. We found that warmer winters lead to earlier growth onset in pines, while oaks are more influenced by soil moisture. Hot and dry summers shortened growth in both species, but oaks maintained

Eucalyptus grandis AUX/INDOLE-3-ACETIC ACID 13 (EgrIAA13) is a novel transcriptional regulator of xylogenesis. [PDF]

Plant Mol Biol, 2022
International audienceKey message Our Induced Somatic Sector Analysis and protein–protein interaction experiments demonstrate that Eucalyptus grandis IAA13 regulates xylem fibre and vessel development, potentially via EgrIAA13 modules involving ARF2 ...

Phenological Shifts in Wood Formation Tracked by Frost Rings Across Two Centuries. [PDF]

Glob Chang Biol
Rapid warming is reshaping plant phenology across ecosystems. We present an indirect retrospective approach to infer cambial phenology by analysing the timing and occurrence of frost rings in three Alpine conifers. We found that the cold spells responsible for frost ring formation typically involve temperature dropping below freezing for an average of ...
