Differentiation and trade-offs of root phosphorus acquisition strategies in different phosphorus efficiency genotypes of Chinese fir SCIE
期刊论文 | 2025 | PLANT AND SOIL
Abstract&Keyword Cite

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 :

Pine wilt disease, caused by the pine wood nematode (PWN), is a devastating systemic disease with significantly impacts on pine species, particularly Pinus massoniana (Masson pine) in South China. This study integrated transcriptomic and metabolomic analyses to identify differentially expressed genes (DEGs) and differentially accumulated metabolites associated with PWN resistance. By comparing the gene expression and metabolic profiles of healthy, mechanically wounded and PWN-infected Masson pine trees at 28 days post-inoculation, we identified that 1310 DEGs were specifically associated with PWN infection after excluding mechanical damage effects. Notably, combined KEGG analysis of transcriptomic and metabolomic data revealed significant enrichment of the alpha-linolenic acid metabolism pathway. Within this pathway, genes such as AOS, LCAT3 and DAD1 exhibited differential expression patterns, highlighting its pivotal role in PWN resistance. Metabolomic analysis revealed that key genes involved in jasmonic acid (JA) biosynthesis and plant hormone signaling showing strong regulation. Additionally, Quantitative Real-Time PCR (qRT-PCR) validation of selected DEGs confirmed the expression patterns observed in the transcriptomic data. Physiological assays also validated changes in key hormone levels, such as JA and methyl jasmonate, which are upregulated in the early stages of plant infection. These results highlight the importance of JA-mediated defence responses and provide novel insights for breeding strategies to improve P. massoniana's resistance to PWN infection.

Abstract :

Optimizing forest management requires a comprehensive understanding of how soil properties and microbial communities evolve across different plantation ages. This study examines variations in soil nutrient dynamics, enzyme activities, and bacterial communities in Schima superba Gardn. & Champ plantations of 10, 15, 27, 55, and 64 years. By analyzing soil from depths of 0-20 cm, 20-40 cm, and 40-60 cm, we identified significant age-related trends in soil characteristics. Notably, nutrient contents, including total organic carbon (TOC), total phosphorus (TP), total carbon (TC), total nitrogen (TN), and nitrate nitrogen (NO3--N), as well as soil water content (SWC), peaked in 55-year-old mature plantations and decreased in 64-year-old over-mature plantations. Enzyme activities, such as urease, sucrase, and acid phosphatase, decreased with soil depth and exhibited notable differences across stand ages. Microbial community analysis indicated the predominance of Acidobacteria, Chloroflexi, Proteobacteria, Actinobacteria, and Verrucomicrobiota in nutrient cycling, with their relative abundances varying significantly with age and depth. Mature and over-mature plantations exhibited higher absolute abundances of functional genes related to methane metabolism, nitrogen, phosphorus, and sulfur cycling. Reduced calcium ion levels were also linked to lower gene abundance in carbon degradation, carbon fixation, nitrogen, and phosphorus cycling, while increased TOC, NH4+-N, NO3--N, and AP correlated with higher gene abundance in methane metabolism and phosphorus cycling. Our findings suggest that long-term cultivation of Schima superba enhances soil nutrient cycling. Calcium ion was identified as a significant factor in assessing soil properties and microbial dynamics across different stand ages, suggesting that extended plantation rotations can improve soil health and nutrient cycling.

Abstract :

Pine wilt disease is a devastating disorder of pine trees, vectored and transmitted by Monochamus alternatus Hope. However, vector control strategies for this disease are hampered by the resistance mechanisms of the pathogen, which hinders the long-term survival of control agents in nature. Serratia marcescens, isolated from Pinus massoniana and the gut of M. alternatus, was selected as the carrier strain for engineered bacteria in this study owing to its symbiotic nature. To realize the possibility of the long-term survival of transgenic bacteria in the gut of M. alternatus and the wild, four sugar-inducible promoters were used to construct transgenic strains. The S. marcescens strains with sugar-inducible promoters exhibited higher fitness than the constitutive strain expressing the Cry3Aa-T toxin, while maintaining a growth curve similar to that of the wild-type strain. The conditional expression of the Cry3Aa-T toxin in S. marcescens was triggered by the presence of sugar, and the lactose-induced transgenic symbiotic strain significantly reduced the survival rate of M. alternatus. Thus, this strategy may enable the engineered bacteria to effectively colonize and spread in the wild, indicating a feasible and sustainable vector control approach against M. alternatus.

Abstract :

MaltAtt-1 is an antimicrobial peptide isolated from Monochamus alternatus with nematocidal activity against pine wood nematode. In this study, a eukaryotic expression system based on Komagataella phaffii GS115 was established, and its secretory expression of MaltAtt-1 was realized. The basic properties and secondary and tertiary structures of the antimicrobial peptide MaltAtt-1 were identified by bioinformatics analysis. MaltAtt-1 is a hydrophilic stable protein, mainly composed of an alpha-helix (Hh), beta-folds (Ee), and irregular curls (Cc). The optimal fermentation conditions for MaltAtt-1 were determined by a single-factor test and the Box-Behnken response surface method, including an induction time of 72 h, induction temperature of 30 degrees C, culture medium of pH 7.6, methanol volume fraction of 2.0%, and an initial glycerol concentration of 1%. The stability of MaltAtt-1 indicated its resistant to UV irradiation and repeated freezing and thawing, but the antibacterial activity decreased significantly under the influence of high temperature and a strong acid and base, and it decreased significantly to 1.1 cm and 0.83 cm at pH 2.0 and pH 10.0, respectively. The corrected mortality of B. xylophilus achieved 71.94% in 3 h at a concentration of 300 mg.L-1 MaltAtt-1 exposure. The results provide a theoretical basis for the antimicrobial peptide MaltAtt-1 to become a new green and efficient nematicide.

Abstract :

The continuous use of chemical pesticides to control nematodes could result in the developing of pesticide-resistant nematodes. Novel nucleic acid pesticides are becoming the focus of pesticide research due to their strong specificity, high efficiency, and environmental friendliness. However, the limited known biochemical targets restrict the development of target pesticides for nematodes. The calcium stress experiments on pine wood nematodes (PWN) showed that 100 mmol/L Ca2+ resulted in longitudinal depression on the PWN body wall, reduced oviposition, and increased corrected mortality. To enrich the biological targets of nematode pesticides, we further investigated the response mechanism of PWN to calcium stress at the molecular level. Differentially expressed gene analysis showed that genes involved in the oxidative phosphorylation (OXPHOS) pathway were significantly enriched. RNA interference results of 6 key genes belonging to four mitochondrial complex I (BXNDUFA2), III (BXQCR8), IV (BXCOX17), V (BXV-ATPaseB, BXV-ATPaseE, BXV-ATPase epsilon) in non-stressed nematodes showed reduction in PWN oviposition, population size, feeding ability, and pathogenicity. The BXNDUFA2 gene interference had the highest inhibitory impact by decreasing the oviposition from 31.00 eggs to 6.75 eggs and PWN population size from 8.27 x 103 nematodes to 1.64 x 103 nematodes, respectively. Interestingly, RNA interference of these 6 key genes in calcium-stressed nematodes also led to increased mor-tality and decreased oviposition of PWN. In summary, calcium stress inhibited the reproductive capacity of PWN by down-regulating key genes BXNDUFA2, BXQCR8, BXV-ATPaseB, BXV-ATPaseE, BXV-ATPase epsilon, and BXCOX17, thereby reducing the pathogenicity. The current results enrich the RNAi targets in PWN and provide a scientific basis for developing novel nucleic nematicides.

Abstract :

The continuous spread of Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle, commonly known as the organism that causes pine wilt disease (PWD), has become a notable threat to forest security in East Asia and southern Europe, and an assessment of the carbon loss caused by PWD damage is important to achieving carbon neutrality. This study used satellite remote sensing and 15-year ground monitoring data to measure the impact of PWD on the carbon storage of Pinus massoniana Lamb. (P. massoniana), the conifer with the largest planted area in southern China. This study showed that the occurrence of PWD had an impact on the increase in carbon storage of P. massoniana. The infected and dead P. massoniana trees accounted for only 1.46 % of the total number of trees but caused a carbon storage loss of 1.99 t/ha, which accounted for 6.23 % of the total carbon sink in healthy P. massoniana forests over the last 15 years. The most pronounced decline in carbon storage occurred in the first five years of PWD invasion. After 10 years of clearcutting and replanting of Schima superba Gardn. et Champ., the increase in carbon storage of the reformed forest far exceeded that of the healthy forest during the same period, which was 2.04 times (10 years) and 1.56 times (15 years) that of the healthy P. massoniana forest. In addition, our study found that during the 15 -year period (from the forest age of 22 to the forest age of 37), the average carbon storage of P. massoniana forest was 31.9 t/ha. This study helps to evaluate the impact of PWD on the carbon sink of pine forests and provides methodological references for analyzing the impact of biological disturbances on the carbon cycle.

Abstract&Keyword Cite

Abstract :

Accurately segmenting an insect from its original ecological image is the core technology restricting the accuracy and efficiency of automatic recognition. However, the performance of existing segmentation methods is unsatisfactory in insect images shot in wild backgrounds on account of challenges: various sizes, similar colors or textures to the surroundings, transparent body parts and vague outlines. These challenges of image segmentation are accentuated when dealing with camouflaged insects. Here, we developed an insect image segmentation method based on deep learning termed the progressive refinement network (PRNet), especially for camouflaged insects. Unlike existing insect segmentation methods, PRNet captures the possible scale and location of insects by extracting the contextual information of the image, and fuses comprehensive features to suppress distractors, thereby clearly segmenting insect outlines. Experimental results based on 1900 camouflaged insect images demonstrated that PRNet could effectively segment the camouflaged insects and achieved superior detection performance, with a mean absolute error of 3.2%, pixel-matching degree of 89.7%, structural similarity of 83.6%, and precision and recall error of 72%, which achieved improvements of 8.1%, 25.9%, 19.5%, and 35.8%, respectively, when compared to the recent salient object detection methods. As a foundational technology for insect detection, PRNet provides new opportunities for understanding insect camouflage, and also has the potential to lead to a step progress in the accuracy of the intelligent identification of general insects, and even being an ultimate insect detector.
