Contrasting Genomic Signatures of Climate Adaptation and Adaptive Plasticity Across the Distribution Ranges of Sessile Oak and European Beech

open access: yesMolecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT The persistence of organisms in changing climates depends on both phenotypic plasticity and adaptation. However, despite extensive research, it remains largely unclear how forest trees will genetically adapt or phenotypically acclimate to future climates.

Nonparallelism of cambium cells in neighboring rows

open access: yesActa Societatis Botanicorum Poloniae, 2014
The periclinal walls of cambial cells in neighboring lineages (rows) may not be parallel when viewed in their radial aspect. This lack of longitudinal parallelism may be so extensive that in active cambium pairs of cells from neighboring rows may be in contact only along restricted segments.

Shaping future forests: how can ecophysiology support climate‐smart forest management?

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Domain pattern in the cambium of young Platanus stems

open access: yes, 2015
In the vascular cambium of Platanus Z and S domains appear in the course of formation of the first annual ring. Their arrangement is connected with the division of the stem into nodes and internodes. In each node a domain of Z and of S type occurs.

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3001-3013, June 2026.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

ARF6 integrates auxin and gibberellin signaling to promote stone cell lignification in pear via the HB49‐MYB169 module

open access: yesNew Phytologist, Volume 250, Issue 6, Page 3747-3768, June 2026.
Summary Stone cells originate from secondary cell wall thickening and contain abundant lignin. Their excessive accumulation compromises pear fruit quality, yet the endogenous hormonal mechanisms governing stone cell formation remain unclear. Here, co‐expression network analysis using transcriptome data – the flesh of 206 sand pear accessions sampled at

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

open access: yesNew Phytologist, Volume 250, Issue 6, Page 3732-3746, June 2026.
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 ...
