Functional coordination and trade-offs are well explored in a conceptual framework of the plant economics spectrum, but how different organs coordinate across these resource dimensions to optimize whole-plant strategies remains largely unclear. We measured 47 functional traits of leaves, stems, coarse roots and fine roots in 33 co-occurring broadleaf tree species from temperate forests in Northeast China, to examine aboveground-belowground coordination across four above-mentioned resource dimensions. We found decoupling between leaves and fine roots in resource acquisition. No significant relationships were observed between leaf and fine root traits associated with acquisition efficiency (leaf photosynthetic rate-specific fine-root length; specific leaf area-specific fine-root area) or spatial occupation (leaf thickness-fine-root diameter; leafing intensity-fine-root branching intensity), supporting functional independence between the two resource-acquiring organs. In contrast, aboveground and belowground organs exhibited coordinated patterns in resource transport. Stem and coarse-root hydraulic efficiency showed positive correlations, and leaf venation density was positively correlated with coarse-root vessel diameters, which also increased with stem vessel diameters. Similar inter-organ relationships were found in resource storage. Nonstructural carbohydrate storage, especially starch, showed synchronized variation between stems and coarse roots, alongside their structural alignments in axial and total parenchyma fractions. As for resource utilization, leaf lamina mechanical resistance (punching force) was positively correlated with coarse-root mechanical strength (modulus of elasticity and rupture), which also positively covaried with corresponding modulus of elasticity and rupture in stems. Additionally, leaf and fine-root tissue density, stem and coarse-root wood density, and stem and coarse-root dry matter content all showed significant positive correlations. These coordinations collectively support the integrated whole-plant strategies in resource transport, storage and utilization.

Young trees are particularly vulnerable to these stressors due to their limited root systems and reduced physiological buffering capacity. In this study, we investigated the individual and combined effects of progressive drought intensity and elevated temperature on the physiological, morphological and oxidative stress responses of Populus nigra seedlings, as well as their capacity to recover following rewatering. Two-year-old seedlings were grown under controlled optimal (20-25 °C) or high (30-35 °C) temperature regimes and subjected to moderate, severe and extreme drought, followed by recovery phases. Plant performance was assessed through measurements of water relations, gas exchange, chlorophyll fluorescence, chlorophyll content, oxidative stress (O₂- accumulation) and aboveground growth traits (i.e., leaf area and biomass, and stem height and biomass). Both drought and heat stress individually impaired plant water status, photosynthetic efficiency and growth, whereas their combination produced synergistic effects, leading to more severe physiological dysfunction, greater oxidative stress and greater growth suppression. Recovery capacity depended strongly on drought severity and temperature conditions. Moderate drought allowed near-complete recovery of physiological function, whereas severe drought resulted in partial recovery, and extreme drought often caused irreversible damage and mortality, particularly under high temperatures. Physiological traits generally recovered faster than morphological traits, indicating that structural growth requires sustained carbon availability beyond initial functional restoration. Multivariate analyses revealed a shift from acquisitive to conservative resource-use strategies under increasing stress, with incomplete reorganization of trait relationships during recovery under high temperature. Our results highlight the vulnerability of young P. nigra seedlings to compound drought-heat stress and suggest that future climate extremes may severely constrain seedling establishment, forest regeneration and ecosystem resilience in riparian and temperate forest systems.</p>","PeriodicalId":23286,"journal":{"name":"Tree physiology","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13358871/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148219977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initial unsupervised graph-based clustering partitioned the dataset into 23 clusters, which were subsequently assigned to 11 major cell-type categories through marker-guided and biologically informed annotation, including meristemoid, coleoptile L1 epidermis, cortex, epidermis, mesophyll precursor, mestome sheath, pericycle, phloem, endodermis, root cap and xylem. Pseudo-time analysis suggested putative vascular-associated trajectories in which captured xylem and phloem cells were ordered along a bifurcating structure extending from meristem populations.

Root cell differentiation exhibited polar patterning, progressing through seven stages from meristems to epidermis, endodermis, cortex and root cap lineages. Leaf development followed a unidirectional trajectory from meristems to mestome sheath cells and coleoptile L1 epidermis, and ultimately to mesophyll cells. We further identified key regulatory factors underlying these cellular differentiations, revealing developmental path differences among roots, stems and leaves.

Elucidating the underlying mechanism is essential for establishing a sustainable and efficient micropropagation system. This study aimed to systematically clarify the physiological and molecular mechanisms underlying the decline in embryogenic potential across successive subculture generations in S. chinensis embryogenic callus, thereby providing a theoretical foundation for optimizing the somatic embryogenesis protocol. An integrated multi-omics approach was employed, combining phenotypic, physiological, transcriptomic and metabolomic analyses of callus at key subculture stages (P1, P4 and P7). The results indicate that embryogenic potential is maintained under a state of balanced energy metabolism and redox homeostasis. Highly embryogenic (P4) callus exhibited active energy and amino acid metabolism, supported by up-regulated hub genes (ScACO3, ScENO1, ScHSP70-4). In contrast, prolonged culture induced severe oxidative stress, characterized by the accumulation of H₂O₂ and O₂-. This oxidative burden activated a ribosomal stress response, with significant up-regulation of ribosomal protein genes (ScRPL7B, ScRPS12, ScRPS11B, ScRPL10A, ScRPL10), ultimately leading to proteostatic collapse and loss of embryogenic capacity. We propose that an 'energy-redox-ribosome axis' serves as the core regulatory cascade determining cell fate under culture stress.

Stomata regulate leaf water and CO2 diffusion, and respond to changes in temperature and relative humidity (RH), two drivers of VPD.

Here, we measured gas exchange under light and dark conditions to investigate the stomatal and cuticular responses to temperature and RH on detached branches in five tropical tree species. Leaf conductance in the dark, when stomata are essentially closed, was not markedly impacted by temperature and RH, suggesting a minimal response of the cuticular pathway to these conditions. We compared six steady-state conductance models incorporating different effects of photosynthesis and evaporative demand on stomatal control. All models performed well (residual standard deviation, σ, < 0.025 mol m-2 s-1), but the best-fitting model (σ = 0.017 mol m-2 s-1) used a nonlinear relationship between photosynthesis and stomatal conductance and incorporated RH rather than vapor pressure difference. All models overestimated the steady-state conductance at high RH. Furthermore, leaf conductance immediately increased after a decrease in RH (wrong-way response), but not after an increase in leaf temperature. This suggests that the mechanisms underlying stomatal response to VPD need further investigation.

The mechanisms by which woody plants cope with karst environments remains unclear. In this study, we established a stem and leaf hydraulic dataset for 696 karst and non-karst woody species (grown on soil substrates) from four climatic zones (tropical, subtropical, temperate and Mediterranean), along with climate variables at each site. We aimed to address the following questions: How do karst and non-karst species differ in their hydraulic traits within the same climate? How do the hydraulic-climate relationships differ between the two plant groups? Our results showed that hydraulic efficiency, stem embolism resistance and minimum leaf water potential were similar between karst and non-karst species in each climate zone. The stem hydraulic safety margin (HSMstem) was higher in karst species than in non-karst species in temperate and Mediterranean regions, but did not differ significantly in the other two climate zones. Leaf hydraulic safety-efficiency was significant and consistent between the two plant groups. However, at the stem level, the hydraulic trade-off was stronger in karst species than in non-karst species. Most hydraulic traits were significantly influenced by the aridity index in karst species, whereas in non-karst species leaf and stem hydraulic efficiencies were associated with the mean annual temperature and precipitation of the warmest quarter, respectively. With increasing aridity, HSMstem tended to increase in karst species but decrease in non-karst species.

Yet predicting how trees recover their water-carbon balance and growth after non-lethal drought remains challenging. To address this, we subjected juvenile Pinus radiata D.Don-a drought-tolerant, strongly isohydric conifer-to moderate (14 weeks) and extended (20 weeks) dry-down periods. We continuously monitored stem radial growth and water reserves for over 6 months with high-resolution dendrometers, alongside weekly measurements of leaf gas exchange, capturing fine-scale dynamics of the water-carbon balance and growth during stress and recovery. We recorded a complete recovery of leaf function and stem growth in all plants after drought release, but the recovery rate depended on drought duration: plants under prolonged stress recovered more slowly. Stomatal conductance returned to control levels after $sim$1.5 and 2.5 weeks following moderate and extended drought, respectively, whereas net $mathrm{CO_{2}}$ assimilation recovered within $sim$1.5 weeks regardless of drought duration. In contrast, cambial activity resumed rapidly, within a few days up to a week, as soon as stem water reserves were refilled. Growth recovery was rapid even in plants that experienced very low water potentials and nearly 2 months in a neutral or negative carbon balance state. Wood formation resumed ahead of photosynthesis recovery, reflecting a decoupling between carbon source and sink processes. Although drought reduced total radial growth, aboveground biomass gain in stressed plants remained comparable to that of well-watered controls, even for those with a growing period halved because of drought. This high degree of growth resilience arose through compensatory growth, with post-stress growth rates 1.4-2.4 times higher than pre-stress rates.

Spanning the period 1930-2019, sampled trees were assigned to three post-2018 vitality classes based on crown transparency: vigorous, intermediate and poor vigour (including dead individuals). We assessed long-term growth and isotopic trajectories in relation to climate variables, with a focus on pan-European summer drought extremes in 1947, 1976, 2003 and 2018. We found that trees with consistently higher growth rates and elevated long-term δ13C values were more susceptible to dieback, whereas surviving trees maintained lower δ13C values. This pattern suggests differences in long-term water-use strategies and/or drought exposure, whilst also partly reflecting canopy position and light-driven assimilation. In contrast, δ18O values sharply increased during drought events, especially in poor-vigour trees, indicating greater reliance on shallow, evaporatively enriched water sources and heightened hydraulic strain under extreme drought. These isotopic trajectories differentiated vitality classes well before visible canopy decline. Our findings indicate that the 2018 drought was not the sole trigger, but rather a tipping point in a long-term dieback process driven by repeated droughts and heatwaves. Tree-ring stable isotopes, particularly when interpreted alongside growth trajectories, provide valuable early warning signals of physiological stress and drought vulnerability.
