Abstract ：
This study investigates how exogenous volatile organic compounds (VOCs) influence the root responses of Cunninghamia lanceolata under nutrient limitations. Specifically, we assessed the differential effects of syringic acid and 1-butene on root morphology, phosphorus acquisition, and stress resilience. Clonal Chinese fir seedlings were utilized to test the effects of treatment with these two exogenous VOCs under both phosphorus supply (1.0 mM KH2PO4) and no phosphorus supply (0 mM KH2PO4) treatments in a controlled pot experiment. Compared to syringic acid, 1-butene significantly enhanced root morphological traits, including root length, specific surface area, and root volume. These morphological changes enhanced the root's ability to acquire phosphorus. Moreover, the addition of 1-butene increased the underground phosphorus use efficiency (PUE) by 25.6% compared to the addition of syringic acid. Furthermore, the addition of 1-butene stimulated higher activity of antioxidant enzymes such as superoxide dismutase (SOD) and peroxidase (POD). Proteomic analysis revealed that 1-butene induced significant changes in root protein expression, particularly in proteins associated with stress responses, phenylpropanoid biosynthesis, and phosphate transport. Compared to syringic acid, 1-butene promoted the differential expression of phosphate transporter proteins, indicating its beneficial effects on the root systems of Chinese firs under low-phosphorus stress. These findings underscore the potential of 1-butene in promoting root efficiency and phosphorus acquisition in forest species, providing insights for enhancing plant adaptation to nutrient limitations.

Abstract ：
Background and AimsChinese fir (Cunninghamia lanceolata), a vital afforestation species in southern China, exhibits genotypic variations in phosphorus (P) acquisition to adapt long-term soil P deficiency environment. This study aimed to elucidate how P-efficiency genotypes balance root morphology, rhizosphere exudation, and arbuscular mycorrhizal fungi (AMF) symbiosis to optimize P acquisition under varying soil P availability.MethodsFourteen genotypes with contrasting P-use efficiencies (PUE) were subjected to low-P (5 mg/kg) and high-P (30 mg/kg) treatments, with or without AMF inoculation. Root morphological traits, exudates, AMF colonization, and carbon-phosphorus allocation were analyzed.ResultsUnder low-P, high-P-efficiency (H-PUE) genotypes increased root length and surface area, reduced root diameter, and enhanced organic acid secretion and acid phosphatase activity. AMF inoculation under low-P suppressed root proliferation in H-PUE, while decreased acid phosphatase activity and dissolved organic carbon content, but increased organic acid concentration and AMF dependency. In contrast, low-P-efficiency (L-PUE) genotypes exhibited a degree of reliance on compensatory root biomass allocation and nonspecific dissolved organic carbon exudation. Principal component analysis revealed H-PUE genotypes synergized structural-symbiotic traits (e.g., fine roots, AMF colonization), whereas L-PUE genotypes relied on rhizosphere activation through acid phosphatase secretion.ConclusionFunctional differentiation in root P-acquisition strategies among Chinese fir genotypes is driven by carbon-phosphorus allocation trade-offs, where H-PUE genotypes optimize P uptake through integrated root morphological plasticity, targeted exudation, and AMF symbiosis, thereby minimizing carbon expenditure. This study elucidates the hierarchical coordination of root morphology, mycorrhizal collaboration, and exudate-mediated rhizosphere remodeling in woody plants, and provides mechanistic criteria for breeding P-efficient varieties and managing phosphorus-limited plantations.

Abstract ：
Improving forest soil quality through effective afforestation and management practices remain a global challenge and understanding the interactions between tree roots and their surrounding soil environment is essential. However, the dynamic relationships between forest tree roots and changing soil conditions are not well understood. This study investigated the adaptive characteristics of Chinese fir (Cunninghamia lanceolata) roots in response to variations in soil water and nutrient availability. We explored roots distribution, architecture, biomass allocation, and associated soil properties in 16-year-old Chinese fir plantations established across different slope positions. Our findings revealed that nutrient-rich surface soil (0-20 cm) varied significantly by slope position, with the upper slope exhibiting lower nutrient content. For example, phosphorus content at the upper slope averaged only 91.30% and 87.50% of that found on the middle and lower slopes, respectively. Additionally, soil moisture content increased as slope position decreased, reaching 15.87-25.86% on the lower slope. Root distribution was most extensive on the middle slope, with horizontal and vertical root spread averaging 2.58 +/- 0.18 m and 1.49 +/- 0.15 m, respectively. Across all slope positions, Chinese fir roots consistently exhibited a fishtail-shaped branching structure. As slope position decreased, soil water and nutrient resources became more abundant, the proportion of root biomass relative to total plant biomass also declined. On the lower slope, root biomass accounted for only 68.89% and 84.56% of the proportion observed on the upper and middle slopes, respectively. These results highlight the importance of understanding root-soil interactions for optimizing root development and plant adaptation. Tailoring water and nutrient management strategies to specific site conditions can enhance Chinese fir root architecture and productivity under varying environmental constraints.

Abstract ：
Increasing nitrogen (N) deposition exacerbates phosphorus (P) limitations in subtropical Chinese fir plantations, yet clonal mechanisms mediating root adaptation to heterogeneous P environments remain unclear. This study investigates the growth and metabolic responses of three clones (Y061/Y020: P-efficient; Y2C: P-sensitive) under N deposition and contrasting P distributions. Elevated N deposition enhanced aboveground and belowground biomass under heterogeneous P conditions, particularly enhancing Y061's root length and surface area. Elevated N deposition significantly increased APase activity while decreasing organic acid secretion, particularly under homogeneous P-deficient conditions. Heterogeneous P supply amplified clonal divergence: P-efficient clones exhibited higher phosphorus absorption efficiency (PAE) than Y2C through root morphological plasticity, while N deposition upregulated APase activity but reduced total organic acids secretion. Metabolomic revealed N-driven shifts in exudate profiles, with lactic, malonic, succinic and oxalic acid increasing while shikimic, quinic and malic acids decreased. Notably, nitrogen absorption efficiency synergistically enhanced PAE under high N conditions. Clones Y061 and Y020 demonstrated superior N and P absorption capabilities, while clone Y2C prioritized enzymatic P mobilization in homogeneous deficiency but showed compromised growth. We demonstrate that N deposition restructures root foraging strategies along a "morphological-enzymatic" axis, where P-efficient clones exploit spatial nutrient heterogeneity through root proliferation rather than organic acid investment. These findings provide actionable solutions: (i) deploying Y061 and Y020 clones in high-N regions improves productivity and (ii) Mixed plantations mimicking heterogeneous P distribution enhance nutrient resilience. Our findings contribute to a deeper understanding of nutrient dynamics and providing targeted strategies for sustainable forestry in acidified subtropical soils.

Abstract ：
Acid deposition has become a significant issue due to increased pollution and forest degradation. To examine the response of acid deposition in Fuzhou, a city in Fujian Province, we investigated the physiology, morphology, osmotic adaptation, photosynthetic characteristics, and antioxidant defense of Pinus massoniana, Cunninghamia lanceolata, Liquidambar formosana, Schima superba, and Phoebe zhennan. Seedlings were subjected to pH levels of 2.5, 3.5, 4.5, and 5.5 in a greenhouse experiment. Plant height, diameter, and biomass increased in the control group (6.5); however, pH 4.5 and 5.5 resulted in tall and thin seedlings. Height and diameter decreased under increased acid deposition specifically at pH 2.5 and 3.5. Biochemical parameters and chlorophyll contents were reduced under low pH levels. The activities of catalase, peroxidase, superoxide dismutase, malonaldehyde, and proline increased initially under low pH, but decreased later due to high acidity, whereas soluble sugar and protein contents were inhibited under higher acidity levels (pH 2.5 and 3.5). The findings showed that the seedlings responded differently but more sensitively to acid deposition below pH 4.5. The exposure to less acidic deposition had a slight effect on the development of these tree seedlings. This trial aids in detecting bioindicators and resilient species to acid deposition existing in forests and urban areas.

Abstract ：
De novo shoot organogenesis (DNSO) enables plants to regenerate shoots from various explants, offering valuable opportunities for research and plant biotechnology applications. While significant progress has been made in understanding regeneration in angiosperms, the regulatory mechanisms in gymnosperms, particularly Chinese fir (Cunninghamia lanceolata), remain poorly understood, despite its importance as a key timber species in China. This study successfully established an efficient DNSO protocol for Chinese fir, identifying six distinct stages in the process through cellular-level analysis. Time-course transcriptome and proteomics analyses revealed dynamic changes in mRNA and protein levels during regeneration. Notably, proteins showed more significant alterations across a broad range of biological processes, often independent of corresponding mRNA changes. Key pathways associated with ethylene metabolism and abiotic stress responses were enriched, highlighting their critical roles in regeneration. Further experiments confirmed that moderate osmotic stress treatments (150 mm mannitol) and ethylene treatment (100 mu m ACC and 5 mu m AgNO3) substantially enhanced DNSO efficiency. In summary, this study uncovers the molecular mechanisms underlying Chinese fir DNSO, providing valuable insights into improving plant regeneration efficiency in this economically important species. These findings contribute to advancements in plant biotechnology and sustainable forestry practices.

Abstract ：
Plant microbiomes are vital for the growth and health of their host. Tree-associated microbiomes are shaped by multiple factors, of which the host is one of the key determinants. Whether different host genotypes affect the structure and diversity of the tissue-associated microbiome and how specific taxa enriched in different tree tissues are not yet well illustrated. Chinese fir (Cunninghamia lanceolata) is an important tree species for both economy and ecosystem in the subtropical regions of Asia. In this study, we investigated the tissue-specific fungal community structure and diversity of nine different Chinese fir genotypes (39 years) grown in the same field. With non-metric multidimensional scaling (NMDS) analysis, we revealed the divergence of the fungal community from rhizosphere soil (RS), fine roots (FRs), and thick roots (TRs). Through analysis with alpha-diversity metrics (Chao1, Shannon, Pielou, ACE, Good's coverage, PD-tree, Simpson, Sob), we confirmed the significant difference of the fungal community in RS, FR, and TR samples. Yet, the overall fungal community difference was not observed among nine genotypes for the same tissues (RS, FR, TR). The most abundant fungal genera were Russula in RS, Scytinostroma in FR, and Subulicystidium in TR. Functional prediction with FUNGuild analysis suggested that ectomycorrhizal fungi were commonly enriched in rhizosphere soil, while saprotroph-parasite and potentially pathogenic fungi were more abundant in root samples. Specifically, genotype N104 holds less ectomycorrhizal and pathogenic fungi in all tissues (RS, FR, TR) compared to other genotypes. Additionally, significant correlations of several endophytic fungal taxa (Scytinostroma, Neonothopanus, Lachnum) with the growth traits (tree height, diameter, stand volume) were observed. This addresses that the interaction between tree roots and the fungal community is a reflection of tree growth, supporting the "trade-off" hypothesis between growth and defense in forest trees. In summary, we revealed tissue-specific, as well as host genotype-specific and genotype-common characters of the structure and functions of their fungal communities.
