Abstract :

Acyl homoserine lactones (AHL), which are extensively studied quorum sensing (QS) signaling molecules in Gram-negative bacteria, play a significant role in regulating plant growth and shaping the rhizosphere ecosystem. In this study, we investigated the effects of continuous planting across multiple generations of the Australian pine Casuarina equisetifolia (Casuarinaceae) on AHL accumulation in its rhizosphere soil. The study aims to identify key AHL and further employs an exogenous supplementation approach to assess their influence on the growth of C. equisetifolia and the associated rhizosphere soil ecosystem. Our findings reveal a progressive increase in total AHL content, rising from 1.76 to 3.65 ng/g with continuous planting generations. The key AHL that significantly alter rhizosphere soil properties under continuous planting conditions are identified as C4-HSL, 3-oxo-C10-HSL, 3-oxo-C12-HSL, and 3-oxo-C14-HSL. Following exogenous treatment with C4-HSL, an increase in its concentration was correlated with a significant enhancement in both the root length and plant height of C. equisetifolia. Conversely, treatments with 3-oxo-C10-HSL, 3-oxo-C12-HSL, and 3-oxo-C14-HSL resulted in a significant reduction in these growth parameters. While all four key AHL contributed positively to the proliferation of soil fungi and actinobacteria, their effects on bacterial populations exhibited variability. Following the exogenous application of the four key AHL, a significant reduction in the activities of urease and protease in the soil was observed. In contrast, the activities of acid phosphatase and cellulase were enhanced, leading to a decrease in the soil's available nitrogen and potassium content, while the available phosphorus content increased. Interaction effect analysis reveals that these key AHL collectively exert a strong positive regulatory effect on soil microbial abundance (0.979**). Furthermore, soil microorganisms show a significant positive correlation with soil enzyme activity (0.997**), whereas soil enzyme activity exhibits a strong negative correlation with the soil's available nutrient content (-0.995**). Additionally, the soil's available nutrient content positively regulates the growth of C. equisetifolia (0.970**). The inhibitory effect of continuous planting on C. equisetifolia growth primarily stems from reduced 3-oxo-C10-HSL levels coupled with elevated 3-oxo-C12-HSL and 3-oxo-C14-HSL concentrations in the rhizosphere. This alteration leads to a decrease in the bacterial population within the soil, which significantly reduces the activities of soil urease and protease, as well as the availability of nitrogen and potassium in the rhizosphere of C. equisetifolia. Consequently, these changes result in markedly diminished root length and dry weight of C. equisetifolia. This study provides a critical theoretical framework for the exogenous application of AHL to modulate C. equisetifolia growth in forest ecological system.

Soil viruses regulate soil nutrient cycling through themselves and their effects on host functioning to impede the growth of continuously planted Casuarina equisetifolia SCIE
期刊论文 | 2025 , 209 | APPLIED SOIL ECOLOGY

Abstract :

Casuarina equisetifolia (C. equisetifolia) is an economically important forest tree, and continuous planting has led to changes in soil microbial diversity and function in the rhizosphere of C. equisetifolia, with a decrease in wood volume of >29.0 %, which has constrained the sustainable development of the industry. Viruses regulate soil microbial diversity, nutrient cycling, fertility, and consequently plant growth. In this study, C. equisetifolia with different numbers of continuous plantings was used as research object, and macroviromics techniques were used to analyze the reasons why soil viruses regulate soil nutrient cycling and thus impede the growth of C. equisetifolia in continuous plantings through their own and their effects on host function. It was shown that continuous planting led to a significant increase in the abundance of 10 characteristic viruses of module 1 in the rhizosphere soil of C. equisetifolia. After parasitizing the host microorganisms, these characteristic viruses reproduced by lysis, and at the same time contributed to a significant decrease in soil microbial biomass carbon, nitrogen and respiration intensity, a significant decrease in soil nutrient cycling and resistance-related enzyme activities, which in turn led to a decrease in available nitrogen, phosphorus and potassium contents of the soil, as well as a significant decrease in the plant height, root length and dry weight of C. equisetifolia. It can be seen that the reproduction mode of the characteristic viruses affects the host number and function, reduces the supply of soil nutrients, and hinders the growth of C. equisetifolia after continuous planting. This study reveals for the first time the different roles of viral propagation strategies in continuous planting and provides a new paradigm for the study of "virus-microbe-plant" interactions.

Rhizobacteria-mediated phenolic acid degradation alleviates replant stress in Casuarina equisetifolia via multi-level soil-plant regulation SCIE

Abstract :

Allelopathic autotoxicity in coastal shelterbelt soils threatens the growth of Casuarina equisetifolia. To address this, we constructed a library of multi-functional bacterial strains enriched on a mixed phenolic acid substrate (vanillic acid: ferulic acid: gallic acid: p-coumaric acid: salicylic acid = 32:6:19:5:8). We evaluated their synergistic phenolic acid degradation, plant growth promotion, and antifungal activities both in vitro and in 100-day greenhouse pot trials. In vitro, Caballeronia arvi strain W3 removed over 99 % of all five phenolic acids, secreted up to 19.1 mg L- 1 indole-3-acetic acid, and 66.4 U min- 1 protease. In pots, Caballeronia arvi strain W3 significantly reduced foliar malondialdehyde by 43.5 %, increased superoxide dismutase and catalase activities by 215 % and 254 %, respectively, and enhanced plant height and dry biomass by 259 % and 371 % compared with the control. Paenibacillus sp. strain W18 restored seed germination from 7.6 % to 55.2 % and raised root viability from 0.138 to 9.27 U g- 1 h- 1 relative to the control. Partial least squares path modeling revealed that bacterial treatment directly drove phenolic acid degradation, which markedly improved soil attributes and rhizosphere community composition, thereby enhancing plant antioxidant and osmotic responses and ultimately growth. These results provide quantitative criteria for targeted microbial remediation of allelopathic soils in coastal shelterbelts.

AHL-Mediated Remodeling of Microbial Communities by Quorum Sensing and Quenching Bacteria Inhibits Casuarina equisetifolia Growth SCIE
期刊论文 | 2025 | JOURNAL OF BASIC MICROBIOLOGY
Abstract&Keyword Cite

Abstract :

Casuarina equisetifolia, a key species in subtropical coastal shelterbelts, faces serious challenges in sustainable plantation management due to continuous planting obstacles. This study explores how AHL-mediated quorum sensing (QS) influences these obstacles by regulating microbial dynamics in the rhizosphere of continuously planted C. equisetifolia. Results show that with increasing generations of continuous planting, the abundance of QS bacteria-especially pathogenic strains-significantly increased, with notable shifts in community composition. The number of QS isolates rose from 32 (FCP) to 68 (SCP) and 81 (TCP), with Enterobacteriaceae being the most abundant. Among 10 identified QS species, Pantoea ananatis showed the highest AHL activity, while Burkholderia lata had the lowest. Short-chain AHL (C4-HSL and C6-HSL) were most common, with P. ananatis producing the highest diversity and concentration. Pathogenicity tests indicated that seven QS bacteria damaged roots and inhibited water uptake, leading to wilting. In contrast, three Burkholderia species were non-pathogenic. Meanwhile, the abundance of quorum quenching (QQ) bacteria decreased significantly across planting generations (94, 70, to 63), and key QQ strains like Bacillus spp. showed no pathogenicity. These findings suggest that continuous planting enriches pathogenic AHL-mediated QS bacteria while reducing beneficial QQ populations, altering microbial community structure and exacerbating replant issues. This study offers important theoretical insights into the mechanisms behind continuous planting obstacles in C. equisetifolia.

Rationalizing Microbial Strategies for Coastal Soil Restoration: Functional Complementarity and Trade-Offs in PGPR-AMF Interactions SCIE
期刊论文 | 2025 | LAND DEGRADATION & DEVELOPMENT
Abstract&Keyword Cite

Abstract :

Coastal sandy soils pose a challenge for microbial nutrient retention due to low organic matter and high leaching. While plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) show promise, their functional synergies in these ecosystems-particularly beyond phosphorus limitation-remain unclear. We investigated their complementary roles in enhancing soil function and Casuarina equisetifolia growth under nutrient-depleted conditions. A 150-day pot experiment evaluated the synergistic effects of PGPR (Paenibacillus kribbensis LB18/LB19, P. cellulositrophicus LB46, Brucella pseudogrignonensis LQ10) and AMF (Funneliformis mosseae) through soil enzymatic activity, nutrient dynamics, and plant growth metrics. Structural equation modeling (SEM) and redundancy analysis (RDA) were employed to dissect soil-plant-microbe interactions. Dual PGPR-AMF inoculation enhanced soil enzymatic activity (dehydrogenase: 1.6-fold; catalase: +57%) and total nitrogen (18.28 mg g-1). However, single inoculation with LQ10 outperformed dual treatments, increasing plant height (+102.2%) and biomass (+254.1%) via root architecture optimization. Indole-3-acetic acid (IAA) synthesis and cellulase activity correlated strongly with nutrient cycling (AN: r = 0.54-0.61; AP: r = 0.56-0.67). SEM identified soil nutrient dynamics (R 2 = 0.506) and antioxidant enzyme networks as growth determinants, with potassium availability (lambda = 0.835) and superoxide dismutase activity (lambda = 0.527) dominating RDA. Structural equation modeling (SEM) revealed that dual inoculation triggered metabolic trade-offs, suppressing host plant secondary metabolism (beta = -0.514) while concurrently enhancing plant physiological resilience, as evidenced by coordinated upregulation of antioxidant enzymes and osmoprotectant levels. Microbial functional traits (e.g., IAA production, cellulolysis) critically regulate soil-plant feedback in nutrient-poor systems. We propose a time-resolved framework for microbial consortia design, where PGPR-AMF synergism is constrained by host carbon allocation thresholds and potassium availability.

Abstract :

The effects of continuous planting on the growth of Casuarina equisetifolia (C. equisetifolia) have severely restricted the sustainable development of the industry. In this study, we investigated the diversity and functional changes of bacteria and fungi in the rhizosphere soil of continuously planted C. equisetifolia and their effects on soil nutrient transformation and C. equisetifolia growth. The results showed that after continuous planting, C. equisetifolia growth was significantly inhibited, the activities of nutrient transformation-related enzymes in rhizosphere soil were reduced, available nutrient content of the soil decreased, and soil bacterial diversity decreased, while fungi diversity increased. After continuous planting, 9 genera of significantly altered characteristic bacteria in the rhizosphere soil of C. equisetifolia were functionally enriched in animal parasites or symbionts, aromatic compound degradation, and nitrate reduction, with contributions mainly from the 3 characterisic bacteria such as Planctopirus, Bacillus, and Acinetobacter. After continuous planting, 7 genera of significantly altered characteristic fungi in the rhizosphere soil of C. equisetifolia were functionally enriched in soil saprotroph, lichen parasite, undefined saprotroph, endophyte, animal pathogen, wood saprotroph, litter saprotroph and plant pathogen, with contributions mainly from the 6 characteristic fungi such as Aspergillu, Fusarium, Saitozyma, Tolypocladium, Mortierella, and Funneliformis. Functional analysis and PLS-SEM equation analysis showed that the growth inhibition of C. equisetifolia due to continuous planting was the result of the joint action of the characteristic bacteria and fungi, but there was a difference between the functions of the two. The function of characteristic bacteria was mainly to provide conditions for the propagation of pathogenic organisms, which reduced soil nutrient content and hindered nutrient uptake by C. equisetifolia. The function of characteristic fungi was primarily to damage soil texture, nourish pathogenic bacteria to infest C. equisetifolia, and damage the root system to inhibit nutrient uptake. Characteristic bacteria and fungi together accelerated the effect of continuous planting on the growth of C. equisetifolia. This study provides an important reference for the cultivation regulation of continuously planted C. equisetifolia.

Abstract&Keyword Cite

Abstract :

根际是由植物根系和土壤微生物之间相互作用形成的一种特殊环境,根际微生物群落的宏基因组是植物微生物组的重要组成部分。植物与根际微生物之间的相互作用是一个复杂的过程。在根际环境中,微生物群落利用复杂的种内和种间信号传导机制招募特定的微生物,协调并控制混合群落的行为,从而影响植物的生长发育和健康。根际微生物能够自发产生、释放特定的信号分子,并能感知其浓度变化,从而调节微生物的群体行为,这一调控系统称为群体感应(quorum sensing, QS)。QS系统的特征是合成和释放特定的信号分子。根际土壤细菌中存在多种QS信号分子,如N-酰基高丝氨酸内酯(AHLs)、二酮哌嗪、扩散信号因子、次生代谢物、植物激素类分子等。AHLs作为细菌中被广泛研究的QS信号分子,在植物与根际微生物的相互作用中发挥重要作用。本文综述了AHLs介导的群体感应机制,并讨论了AHLs在植物与根际微生物相互作用中的调节作用,包括AHLs对植物的生长发育、逆境耐受性和抗病性等方面的有益影响,以及AHLs介导的QS系统调控导致的根际致病菌对植物的有害影响,同时还探讨了基于AHLs的群体淬灭对植物-根际微生物相互作用的影响,以期为植物健康与农业生产提供新的思路和方法,推动可持续农业的发展。
