In this study, we investigate how silver fir (Abies alba Mill.) responds to experimental drought stress, more specifically, atmospheric drought caused by high vapor pressure deficit (VPD), by analyzing the gene expression and DNA methylation profiles of different organs alongside physiological variables under well-watered, drought and recovery conditions. Roots exhibited a stronger transcriptomic response than leaves, with 50 times more altered transcripts, revealing their value for assessing water stress in this species through the expression of genes involved in water transport. In addition, brassinosteroid-related genes can serve as stress markers both in roots and leaves. VPD-induced drought also affected DNA methylation, which, like transcriptomic and physiological variables, begins to normalize once the stress is over, suggesting some resilience to drought. However, A. alba struggles to improve intrinsic water use efficiency, which raises its vulnerability to VPD-induced drought. Our results suggest that silver fir forests might be able to cope with short drought events, but prolonged periods of water shortage, which are likely to increase with climate change, may surpass their resilience thresholds, increasing the likelihood of hydraulic failure and carbon starvation.</p>","PeriodicalId":23286,"journal":{"name":"Tree physiology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144837906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under flooding conditions, physiological and cellular stress was more pronounced in P. deltoides 'D-124' than in the hybrid clone '52-225,' as evidenced by lower transpiration (E), photosynthesis (A), and chlorophyll content.

This study aimed to investigate the effects of an AM fungal inoculation with Rhizophagus intraradices on biomass production, leaf gas exchange, chlorophyll fluorescence response, and leaf GA metabolism in trifoliate orange (Poncirus trifoliata) plants under drought stress. R. intraradices exhibited a pronounced affinity for root colonization, achieving rates between 78.52% and 85.45%, although drought treatment led to a decrease in this colonization. Compared with non-AM plants, AM plants exhibited significantly higher biomass production of leaves, stems and roots, irrespective of soil moistures, underscoring their resilience and growth superiority during drought. Arbuscular mycorrhizal trifoliate orange plants displayed lower bioactive GA1 and GA3 levels than non-AM plants under drought. This reduction was associated with the down-regulation of genes involved in GA biosynthesis (PtCPS, PtKAO and PtGA3ox) and the up-regulation of the GA deactivation gene (PtGA2ox) produced by AM fungal inoculation. Arbuscular mycorrhizal plants also displayed higher photosynthetic physiological activities than non-AM plants, as evidenced by significantly higher chlorophyll index, nitrogen balance index, maximum quantum yield of photosystem II, steady-state quantum yield, transpiration rate, net photosynthetic rate, intercellular CO2 concentration and stomatal conductance, as well as lower non-photochemical quenching during drought. Interestingly, bioactive GA3 levels, rather than GA1, showed a significantly negative correlation with leaf gas exchange parameters and light energy conversion efficiency during photosynthesis. In summary, AM fungal inoculation led to a reduction in leaf active GA levels by inhibiting GA biosynthesis and promoting GA deactivation, which contributed to 'drought avoidance' by suppressing biomass production; AM plants recorded superior photosynthetic physiological activities, associated with the regulation of GA3, not GA1.</p>","PeriodicalId":23286,"journal":{"name":"Tree physiology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144544994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While radial variability of sap flow has been identified as a substantial source of error in estimating whole-tree transpiration, there has yet to be a universal adoption of a single scaling method. This study evaluated the temporal dependency of the radial profile of sap flux on seasonality and meteorological drivers and assessed the accuracy of six radial profile estimation methods of varying complexity in comparison with a robust multi-point estimation of sap flow. Of the six scaling approaches examined in this study, the use of a linear regression to compare outer flow rates with whole tree flow generated the least error when compared with the multi-point estimation (0.6% error). A cross validation demonstrated that statistical models remain accurate when applied to individuals not included in the training of the statistical models (mean adjusted R2 = 0.961). These findings suggest that future sap flux studies seeking to scale to whole-tree or stand level could robustly instrument a subset of trees with multiple radial depth measurement points to train one of the statistical models described in this study.

However, limited attention has been given to how forest management strategies, such as tree species mixing, influence the quantity and quality of root exudates, particularly across different stand ages.

DC.) at four stand ages (25, 36, 46 and 63 years) to examine the root exudation rate of carbon (REC) and the metabolomic profile of exudates. We also assessed stand characteristics, root traits and soil properties to explore their interactions with root exudation. Results indicated that species mixing had minimal effects on REC, except in the 36-year-old stand. However, tree species mixing significantly influenced the metabolome of root exudates, with the primary differentially accumulated metabolites (DAMs) being amino acids and peptides, fatty acids and shikimates and phenylpropanoids. The mixing effects on all metabolites significantly varied with stand age, with the maximum (26.92-46.75%) occurring at the 46- or 63-year-old stands and the minimum (-17.64 to 6.04%) occurring at the 25- or 36-year-old stands.

Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses revealed that carbohydrate metabolism and starch and sucrose metabolism were more active in k15 than in m2. In addition, k15 increased starch degradation by upregulating two genes encoding β-amylase (BAM), leading to the accumulation of higher levels of soluble sugars than m2 under drought stress.

We also performed a small-scale common garden experiment with imposed higher temperature and drought stress during which we sampled for transcriptomes using RNAseq and performed physiological measurements to obtain insights into the intraspecific responses among aspen lineages to such abiotic stressors.

Phloem and cambial reactivation have been studied in relation to leaf-out, but not in relation for floral phenology. We sampled the stems of three co-occurring temperate broad-leaved woody plants and one shrub to investigate the timing of phloem and cambial reactivation in relation to spring floral production and environmental factors.
