Estimation de la xylogénèse chez l'épinette noire entre 1950 et 2010 [PDF]

, 2011
Selon les reconstitutions des variations de température à la surface de la terre, le 20e siècle s'est démarqué par des températures particulièrement chaudes dans le contexte des dernières mille années. De plus, la vitesse du réchauffement est plus élevée

Modification of xylan in secondary walls alters cell wall biosynthesis and wood formation programs and improves saccharification

Plant Biotechnology Journal, Volume 23, Issue 1, Page 174-197, January 2025.
Summary Wood of broad‐leaf tree species is a valued source of renewable biomass for biorefinery and a target for genetic improvement efforts to reduce its recalcitrance. Glucuronoxylan (GX) plays a key role in recalcitrance through its interactions with cellulose and lignin.

The role of cytokinins in clubroot disease [PDF]

, 2016
Clubroot (Plasmodiophora brassicae) is a pathogen of Brassicaceae that causes significant reductions in yield as a consequence of gall formation in the root and hypocotyl of infected plants.

Thinning enhances whitebark pine (Pinus albicaulis) growth and resin duct defenses

Ecosphere, Volume 15, Issue 12, December 2024.
Abstract Whitebark pine (Pinus albicaulis) is an important component of high‐elevation ecosystems throughout the northern Rocky Mountains; however, the species was recently listed as “threatened” under the Endangered Species Act due to widespread mortality throughout its native range.

Combining Dendrometer Series and Xylogenesis Imagery—DevX, a Simple Visualization Tool to Explore Plant Secondary Growth Phenology

Frontiers in Forests and Global Change, 2019
Determining the effect of a changing climate on tree growth will ultimately depend on our understanding of wood formation processes and how they can be affected by environmental conditions. In this context, monitoring intra-annual radial growth with high

A new perspective on tree growing season determination

Journal of Biogeography, Volume 51, Issue 12, Page 2334-2337, December 2024.
Abstract Defining plant development timing through seasonal growth and dormancy phases is a valuable proxy for studying climate change and serves as an annual bioindicator. However, current methods for determining the growing season vary due to species‐specific interpretations and differing understandings of its main drivers. Körner et al.

Caspase inhibitors affect the kinetics and dimensions of tracheary elements in xylogenic Zinnia (Zinnia elegans) cell cultures [PDF]

, 2010
Background The xylem vascular system is composed of fused dead, hollow cells called tracheary elements (TEs) that originate through trans-differentiation of root and shoot cambium cells. TEs undergo autolysis as they differentiate and mature.

Wood nutrients: Underexplored traits with functional and biogeochemical consequences

New Phytologist, Volume 244, Issue 5, Page 1694-1708, December 2024.
Summary Resource storage is a critical component of plant life history. While the storage of nonstructural carbohydrates in wood has been studied extensively, the multiple functions of mineral nutrient storage have received much less attention. Here, we highlight the size of wood nutrient pools, a primary determinant of whole‐plant nutrient use ...

A meta-analysis of cambium phenology and growth: linear and non-linear patterns in conifers of the northern hemisphere [PDF]

, 2017
Background and Aims Ongoing global warming has been implicated in shifting phenological patterns such as the timing and duration of the growing season across a wide variety of ecosystems.

Tracking climate vulnerability across spatial distribution and functional traits in Magnolia gentryi in the Peruvian tropical montane cloud forest

American Journal of Botany, Volume 111, Issue 9, September 2024.
Abstract Premise Understanding the responses of functional traits in tree species to climate variability is essential for predicting the future of tropical montane cloud forest (TMCF) tree species, especially in Andean montane environments where fog pockets act as moisture traps.
