Xylogenesis under climatic stress: wood anatomical evidence of harsh conditions

Les
Xylogenesis – the process of secondary xylem formation – is tightly regulated by hormonal, physiological, and environmental signals, but becomes highly vulnerable under extreme climatic stress.

Glucuronoyl Esterase of Pathogenic Phanerochaete carnosa Induces Immune Responses in Aspen Independently of Its Enzymatic Activity

Plant Biotechnology Journal, Volume 24, Issue 2, Page 602-619, February 2026.
ABSTRACT Microbial enzymes expressed in plants add new functionalities but occasionally trigger undesirable immune responses. Phanerochaete carnosa glucuronoyl esterase (PcGCE) hydrolyses the bond between lignin and 4‐O‐methyl‐α‐D‐glucuronic acid substituent of glucuronoxylan.

Identifying the main drivers for the production and maturation of Scots pine tracheids along a temperature gradient [PDF]

, 2017
Even though studies monitoring the phenology and seasonal dynamics of the wood formation have accumulated for several conifer species across the Northern Hemisphere, the environmental control of tracheid production and differentiation is still ...

Low temperature limits for root growth in alpine species are set by cell differentiation [PDF]

, 2017
Plant growth in cold climates is not limited by carbon assimilation (source activity) but rather by reduced carbon investment into new tissues (sink limitation). It has been hypothesized that all cold-adapted plants face similar growth constraints at low

The Sequence of Drought‐Driven Stomatal Closure, Stem Xylem Embolism, Dehydration, and Aquaporin Gene Expression Differs Among Species

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Stem dehydration is critical in predicting drought‐driven tree mortality. Yet, how it coordinates with stomatal closure, xylem embolism, and aquaporin‐mediated water transport regulation remains unknown. Two angiosperms (beech and olive) and two conifers (pine and juniper) of contrasted embolism resistance were selected to assess the sequence ...

Large‐scale atmospheric variability entails differential modes of seasonal tree growth in the Mediterranean Basin

Journal of Ecology, Volume 113, Issue 9, Page 2652-2667, September 2025.
This work demonstrates the control of teleconnections on seasonal tree growth through local climate across the Mediterranean basin. Despite the constant link between the East Atlantic Pattern and temperature, synergies among teleconnections point to an east–west dipole in tree seasonal growth, driven by precipitation variability.

Age-related phenological and anatomical response of European beech (Fagus sylvatica L.) under severe summer drought conditions

Journal of Forest Science
The year 2018 was distinguished by a warm summer with extended periods of low or no precipitation. In this context, we investigated the intra-annual dynamics of xylem differentiation phases and quantitative vessel anatomy to analyse the age effect on the

Effects of soil warming and nitrogen foliar applications on bud burst of black spruce [PDF]

, 2016
Key message: In mature black spruce, bud burst process is anticipated by soil warming, while delayed by foliar applications of nitrogen; however, the effects depend on growth conditions at the site. Abstract: The observation of phenological events can

Multiyear Drought Strengthens Positive and Negative Functional Diversity Effects on Tree Growth Response

Global Change Biology, Volume 31, Issue 9, September 2025.
Mixed‐species forests may help trees better cope with increasing drought stress under climate change. We analyzed tree‐ring growth from nearly 1000 trees across 16 species in 9 experimental plantations across Europe to understand how tree diversity influences drought responses.
