Abstract :

In eukaryotes, the retromer complex plays a crucial role in the sorting and retrograde transport of cargo proteins from endosomes to the trans-Golgi network (TGN). Despite its importance, the molecular details of this intracellular transport process remain unclear. Here, we have identified a Golgi-associated retrograde protein (GARP) complex as a mediator of vesicle transport that facilitates the recruitment of the retromer complex to the TGN to exert its functions. The GARP complex is mainly localized in the TGN where it interacts with the retromer complex. This interaction is evolutionarily conserved across species. Furthermore, we identified FgKex2 and FgSnc1 as cargo proteins in the GARP/retromer-mediated recycling pathway. Loss of GARP or retromer results in a complete missorting of FgKex2 and FgSnc1 into the vacuolar degradation pathway, which affects the growth, development, biogenesis of toxisomes and pathogenicity of Fusarium graminearum. In summary, we demonstrate for the first time that GARP promotes the recruitment of retromer from endosomes to the TGN, thereby establishing a GARP/retromer transport pathway that coordinates the recycling of cargo proteins FgKex2 and FgSnc1. This process is essential for maintaining sustained growth and development and significantly contributes to the pathogenicity of F. graminearum.

Abstract :

由香蕉枯萎病菌4号生理小种(Fusarium oxysporum f. sp.cubense tropical race 4,Foc TR4)引起的香蕉枯萎病是全球香蕉产业面临的重大土传病害,其土壤中的分生孢子和厚垣孢子是主要侵染源。构巢曲霉(Aspergillus nidulans)C2H2型锌指转录因子FlbC是调控分生孢子发育的关键因子。本研究在Foc TR4中鉴定到FlbC的同源基因FocFlbC,利用原生质体介导的遗传转化技术构建了其敲除突变体(ΔFocFlbC)和回补菌株,并分析了该蛋白的亚细胞定位和生物学功能。结果显示,FocFlbC定位于菌丝和分生孢子的细胞核。与野生型相比,ΔFocFlbC突变体在麦芽糖培养基上的菌丝生长速率显著降低,但在其他碳源培养基上无明显差异;该突变体在不同碳源培养基上的产孢量均显著降低,其中在麦芽糖培养基上野生型与突变体的产孢量比率最高,显著高于其他碳源培养基。虽然FocFlbC缺失突变对Foc TR4生物量累积和分生孢子萌发无显著影响,但与野生型相比,该突变体表现出:细胞壁和盐胁迫耐受性降低;α-淀粉酶、滤纸酶及β-1,4-D-葡聚糖酶活性下降,且相应水解酶基因的表达水平下调;以及致病力减弱。上述表型缺陷均可被回补菌株恢复。综上,FocFlbC不仅调控Foc TR4在麦芽糖培养基上的菌丝生长与产孢,还参与调控细胞壁完整性、盐胁迫响应、水解酶合成以及致病力等多个重要生物学过程,为深入揭示Foc TR4生长发育和致病分子机制奠定了理论基础。

Abstract :

香蕉枯萎病(Fusarium wilt)是由尖镰孢古巴专化型(Fusarium oxysporum f. sp.cubense,Foc)引起的一种土传病害,严重威胁着香蕉生产。生物防治是香蕉枯萎病综合治理体系中的重要组成部分。本研究以同一生境中的2种二倍体香蕉(斑叶蕉、野蕉)和2种三倍体香蕉(天宝矮蕉、矮杆大蕉)为研究对象,通过高通量测序分析其根部内生细菌群落的多样性,发现二倍体植株的内生细菌群落多样性高于三倍体植株;这两种类型香蕉根部内生细菌群落结构也存在一定的差异,二倍体植株中芽孢杆菌属(Bacillus)、慢生根瘤菌属(Bradyrhizobium)等重要生防微生物的物种相对丰度高于三倍体植株。从二倍体香蕉(紫苞芭蕉、斑叶蕉)中分离筛选到14株对Foc具有拮抗效果的内生细菌,盆栽试验结果表明其中2株贝莱斯芽孢杆菌(Bacillus velezensis) ZB-1和Z-7灌根处理均能有效减轻由Foc引起的香蕉枯萎病的发病程度,其脂肽提取物可影响Foc分生孢子及菌丝的形态建成,导致Foc分生孢子产量分别下降了99.02%和98.67%,并破坏菌丝生物膜系统及抑制脂质代谢。本研究表明二倍体香蕉富含有益生防菌群,为开发基于微生物调控的香蕉枯萎病绿色防控技术体系提供了重要的理论依据和菌种资源。

The Signal Peptidase MoSpc2 Orchestrates Fungal Development, Protein Secretion and Pathogenicity in Magnaporthe oryzae SCIE
期刊论文 | 2025 , 18 (1) | RICE
Abstract&Keyword Cite

Abstract :

The signal peptidase complex (SPC) is a crucial membrane enzyme complex involved in the process of protein secretion and maturation in both prokaryotic and eukaryotic cells. SPC is responsible for the cleavage of N-terminal signal sequences from nascent proteins, a sequence of amino acids that directs the newly synthesized protein to the secretory pathway. The yeast SPC is composed of four subunits: Spc1, Spc2, Spc3, and Sec11. To understand how SPC functions in the fungal plant pathogen, we identified the SPC component gene MoSPC2 and characterized its functions in M. oryzae. Through measuring the colony diameter of the Delta Mospc2 mutant and control strains on culture medium plates, quantifying conidia production, observing conidial morphology, and assessing pathogenicity on rice and barley plants, we found that MoSpc2 contributes to fungal growth, asexual development, and pathogenicity. Since host-derived reactive oxygen species (ROS) are crucial for rice to defend against M. oryzae, we further investigated the role of MoSpc2 in ROS modulation. Our results indicate that MoSpc2 plays a pivotal role in suppressing the accumulation of ROS and regulating the activities of extracellular peroxidases and laccases. Notably, MoSpc2 mediates the accumulation and secretion of the effector protein MoSlp1. Furthermore, using affinity purification, we discovered MoSpc2-interacting proteins and identified potential SPC interactors. These candidates provide a foundation for future mechanistic studies aimed at elucidating their functional roles in SPC complex assembly and pathogenic regulation. Our results highlight the significance of the SPC component gene MoSPC2 involvement in fungal development and pathogenicity and widen our understanding of the connections between the SPC and fungal pathogenesis.

Abstract :

The conidia produced by Fusarium oxysporum f. sp. cubense (Foc), the causative agent of Fusarium Wilt of Banana (FWB), play central roles in the disease cycle, as the pathogen lacks a sexual reproduction process. Until now, the molecular regulation network of asexual sporogenesis has not been clearly understood in Foc. Herein, we identified and functionally characterized thirteen (13) putative sporulation-responsive genes in Foc, namely FocmedA(a), FocmedA(b), abaA-L, FocflbA, FocflbB, FocflbC, FocflbD, FocstuA, FocveA, FocvelB, wetA-L, FocfluG and Foclae1. We demonstrated that FocmedA(a), abaA-L, wetA-L, FocflbA, FocflbD, FocstuA, FocveA and Foclae1 mediate conidiophore formation, whereas FocmedA(a) and abaA-L are important for phialide formation and conidiophore formation. The expression level of abaA-L was significantly decreased in the Delta FocmedA(a) mutant, and yeast one-hybrid and ChIP-qPCR analyses further confirmed that FocMedA(a) could bind to the promoter of abaA-L during micro- and macroconidiation. Moreover, the transcript abundance of the wetA-L gene was significantly reduced in the Delta abaA-L mutant, and it not only was found to function as an activator of micro- and macroconidium formation but also served as a repressor of chlamydospore production. In addition, the deletions of FocflbB, FocflbC, FocstuA and Foclae1 resulted in increased chlamydosporulation, whereas FocflbD and FocvelB gene deletions reduced chlamydosporulation. Furthermore, FocflbC, FocflbD, Foclae1 and FocmedA(a) were found to be important regulators for pathogenicity and fusaric acid synthesis in Foc. The present study therefore advances our understanding of the regulation pathways of the asexual development and functional interdependence of sporulation-responsive genes in Foc.

Two distinct SNARE complexes mediate vesicle fusion with the plasma membrane to ensure effective development and pathogenesis of Fusarium oxysporum f. sp. cubense SCIE

Abstract :

SNAREs (soluble N-ethylmaleimide-sensitive factor attachment protein receptors) facilitate docking and fusion of vesicles with their target membranes, playing a crucial role in vesicle trafficking and exocytosis. However, the spatial assembly and roles of plasma membrane (PM)-associated SNAREs in phytopathogen development and pathogenicity are not clearly understood. In this study, we analysed the roles and molecular mechanisms of PM-associated SNARE complexes in the banana Fusarium wilt fungus Fusarium oxysporum f. sp. cubense tropical race 4 (FocTR4). Our findings demonstrate that FocSso1 is important for the fungal growth, conidiation, host penetration and colonization. Mechanistically, FocSso1 regulates protein secretion by mediating vesicle docking and fusion with the PM and hyphal apex. Interestingly, a FocSso1-FocSec9-FocSnc1 complex was observed to assemble not only at the fungal PM but also on the growing hyphal apex, facilitating exocytosis. FocSso2, a paralogue of FocSso1, was also found to form a ternary SNARE complex with FocSec9 and FocSnc1, but it mainly localizes to the PM in old hyphae. The functional analysis of this protein demonstrated that it is dispensable for the fungal growth but necessary for host penetration and colonization. The other subunits, FocSec9 and FocSnc1, are involved in the fungal development and facilitate host penetration. Furthermore, FocSso1 and FocSnc1 are functionally interdependent, as loss of FocSso1 leads to mis-sorting and degradation of FocSnc1 in the vacuole and vice versa. Overall, this study provides insight into the formation of two spatially and functionally distinct PM SNARE complexes and their involvement in vesicle exocytosis to regulate development and pathogenicity of FocTR4.

The Signal Peptidase FoSpc2 Is Required for Normal Growth, Conidiation, Virulence, Stress Response, and Regulation of Light Sensitivity in Fusarium odoratissimum SCIE

Abstract :

Signal peptidase (SPase) is responsible for cleavage of N-terminal signal peptides in most secretory precursor proteins and many membrane proteins during maturation. In this study, we identified four components of the SPase complex (FoSec11, FoSpc1, FoSpc2, and FoSpc3) in the banana wilt fungal pathogen Fusarium odoratissimum. We proved that interactions exist among the four SPase subunits by bimolecular fluorescence complementation (BiFC) and affinity purification and mass spectrometry (AP-MS) assays. Among the four SPase genes, FoSPC2 was successfully deleted. FoSPC2 deletion caused defects in vegetative growth, conidiation, and virulence. Loss of FoSPC2 also affected the secretion of some pathogenicity-related extracellular enzymes, suggesting that SPase without FoSpc2 may have a lower efficiency in managing the maturation of the extracellular enzymes in F. odoratissimum. In addition, we found that the & UDelta;FoSPC2 mutant had increased sensitivity to light, and the colonies of the mutant grew faster under all-dark conditions than under all-light conditions. We further observed that deletion of FoSPC2 affected expression of the blue light photoreceptor gene FoWC2, leading to cytoplasmic accumulation of FoWc2 under all-light conditions. Since FoWc2 has signal peptides, FoSpc2 may regulate the expression and subcellular localization of FoWc2 indirectly. Contrary to its response to light, the & UDelta;FoSPC2 mutant displayed a significant decreased sensitivity to osmotic stress, and culturing the mutant under osmotic stress conditions restored both the localization of FoWc2 and light sensitivity of the & UDelta;FoSPC2, suggesting that a cross talk between osmotic stress and light response pathways in F. odoratissimum and FoSpc2 takes part in these processes.IMPORTANCE In this study, we identified four components of SPase in the banana wilt pathogen Fusarium odoratissimum and characterized the SPase FoSpc2. Loss of FoSPC2 affected the secretion of extracellular enzymes, suggesting that SPase without FoSpc2 may have a lower efficiency in managing the maturation of the extracellular enzymes in F. odoratissimum. In addition, this is the first time that we have found a relationship between the SPase and fungal light response. Deletion of FoSPC2 resulted in decreased sensitivity to the osmotic stresses but with increased sensitivity to light. Continuous light inhibited the growth rate of the & UDelta;FoSPC2 mutant and affected the cellular localization of the blue light photoreceptor FoWc2 in this mutant, but culturing the mutant under osmotic stress both restored the localization of FoWc2 and eliminated the light sensitivity of the & UDelta;FoSPC2 mutant, suggesting that loss of FoSPC2 may affect a cross talk between the osmotic stress and light response pathways in F. odoratissimum. In this study, we identified four components of SPase in the banana wilt pathogen Fusarium odoratissimum and characterized the SPase FoSpc2. Loss of FoSPC2 affected the secretion of extracellular enzymes, suggesting that SPase without FoSpc2 may have a lower efficiency in managing the maturation of the extracellular enzymes in F. odoratissimum.
