Xylogenesis in the early life stages of maritime pine [PDF]

Forest Ecology and Management, 2018
Abstract Trees change throughout their life stages, and although age-dependent changes are reported in the literature, the early life stages of trees are often excluded from these studies. The sapling/pole life stage corresponds to the establishment phase of a tree in the forest. To understand how wood formation changes in the early growing stages we

Landscape Influences on Microclimate and Tree Growth Cessation in a Semi‐Arid Montane Forest

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 1, January 2025.
Abstract As climate change impacts the severity and frequency of drought, knowledge of hillslope‐to‐watershed scale ecohydrology is increasingly necessary to inform appropriate conservation, restoration, and management of forested ecosystems. In mountain environments, spatial patterns of water and energy organize forest productivity at plot, hillslope,

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.

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.

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.

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 ...

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

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.

Spermine and spermidine inhibit or induce programmed cell death in Arabidopsis thaliana in vitro and in vivo in a dose‐dependent manner

The FEBS Journal, Volume 291, Issue 16, Page 3665-3685, August 2024.
Polyamines have previously been linked to modulation of programmed cell death (PCD), but the reports on their pro‐death and pro‐survival effects in plants are frequently contrasting. In this work, we show that exogenous polyamines spermidine and spermine may inhibit or induce PCD in Arabidopsis thaliana in a dose‐dependent manner.

Complex environmental control of growth in a dominant Mediterranean‐alpine shrub species

Journal of Ecology, Volume 112, Issue 7, Page 1516-1532, July 2024.
These findings improve the understanding of the species' ecological niche and show that preceding photosynthetic activity helps Cytisus galianoi to perform even under unfavourable conditions in winter and during the active growth phase. Abstract Mediterranean‐alpine plants are exposed to harsh conditions, forcing them to perform with well‐adapted ...
