Abstract ：
Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) is one of the main afforestation tree species in southern China. Continuous planting for multiple generations has led to a decrease in the content of available phosphorus in the soil. To adapt to low phosphorus stress, plants develop a series of physiological, biochemical, and developmental responses through self-regulation. Recent studies have shown that miRNAs play a regulatory role in plants' responses to low phosphorus stress. However, the regulatory mechanism of miRNAs in Chinese fir in response to low phosphorus stress is still unclear. Here, we performed small RNA sequencing on the Chinese fir roots treated with normal phosphorus and low phosphorus and identified a total of 321 miRNAs, including 139 known miRNAs and 182 new miRNAs, with 43 differentially expressed miRNAs (DEMs). Integrative analysis combined with degradome sequencing data revealed that 193 miRNAs (98 known and 95 new) targeted 469 genes, among which 23 DEMs targeted 44 genes. Gene enrichment analysis indicated that under low phosphorus stress, transcription and transcriptional regulation, as well as signal transduction, were significantly activated in Chinese fir. Modules in the miRNA-target pathways, such as miR166/HD-ZIP III, miR169/NFYA7, miR529/SPL, and miR399/UBC23, may be the key regulatory factors in the response to low phosphorus stress in Chinese fir. In addition, we found that PC-3p-1033_8666 was significantly downregulated and that PC-5p-3786_2830 was significantly upregulated, which presumably respond to low phosphorus stress by indirectly affecting phosphorus-related hormone signaling or PSR genes. The identified miRNA-target network and significantly activated pathways in this study provide insights into the post-transcriptional regulatory mechanisms of Chinese fir adapting to low phosphorus environments, which can offer theoretical references for the stress resistance and superior variety breeding of Chinese fir.

Abstract ：
Climate change and strait isolation during the glacial period had a profound effect on the differentiation of gymnosperms on both sides of the Taiwan Strait. The taxonomic status and population structure of Cunninghamia konishii (Taiwan) and C. lanceolata (mainland China) remain contentious due to conflicting morphological and molecular evidence. Thus, we sampled 92 accessions from seven natural populations, six from mainland China and one from Taiwan, and conducted high-throughput genotyping-by-sequencing (GBS) analysis. The northern marginal population exhibited the lowest genetic diversity (theta pi = 4.828 x 10-3), while the Taiwan population had the highest (theta pi = 5.821 x 10-3), reflecting its role as a glacial refugium, while mainland populations retained lower diversity due to post-glacial bottlenecks. There was little difference in Tajima's D values of selection pressure between mainland China and Taiwan. However, significant gene flow (Nm = 2.839) was observed, combined with low FST values (0.072-0.122), which indicate low genetic differentiation among C. lanceolata and C. konishii. Migration analysis indicated a high probability of unidirectional gene flow from mainland China to Taiwan, with the Dongshan Land Bridge facilitating pre-glacial gene flow. We conclude that C. konishii represents an ecotype of C. lanceolata , shaped by environmental plasticity and incomplete isolation. This study enhances our understanding of the gene flow and evolutionary processes shaping the species and offers new insights into their taxonomic classification.

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 ：
The development of branches on the lower part of the trunk plays a decisive role in the early growth of trees and influences the wood quality of their most valuable sections. This study investigated the effects of planting density on the horizontal and vertical spatial distribution, branch morphology, and branch quantity characteristics of two elite clones of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.), Yang 061 and Yang 020. The results revealed the following distinct responses between the two clones: Yang 061 exhibited significant reductions in branch base diameter and length under a higher planting density, alongside an increased frequency of small branches (<15 mm), but there was no significant effect on branch angles. In contrast, Yang 020 was primarily influenced by genetic factors, with planting density exerting minimal impact. This clone optimized resource allocation by promoting the mortality of lower branches through angle adjustments, resulting in negligible changes to branch development across different planting densities. Pronounced differences in vertical and horizontal branch distributions were observed in areas with significant light disparities, such as the middle crown and northeast direction, for both clones, with increased planting density exacerbating these differences. In conclusion, increasing the planting density of Yang 061 from 2500 to 3333 treesha(-1) can effectively reduce its branch size; whereas, increasing the planting density of Yang 020 from 3000 to 5100 treesha(-1) can slightly decrease its branch size without affecting its early rapid growth, thereby achieving a synergistic improvement in both timber yield and quality. These findings highlight the importance of interactions between genetic traits and planting density in shaping branch development and spatial distribution patterns, providing insights to optimize planting density for improving the productivity and wood quality of Cunninghamia lanceolata plantations.

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 ：
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.
