A multitude of biotic and abiotic stress factors do harm to plants by bringing about diseases inhibiting normal growth development. As a pivotal signaling molecule, salicylic acid (SA) plays crucial roles in plant tolerance responses both stresses, thereby maintaining improving yields under stress. In view this, this paper mainly discusses the role SA stresses plants. regulates expression genes involved defense pathways, thus enhancing immunity. addition, mitigates negative effects acts as molecule induce stress-responsive synthesis stress-related proteins. also improves certain yield-related photosynthetic indexes, crop yield On other hand, with molecules, such jasmonic (JA), auxin, ethylene (ETH), so on, regulating This reviews recent advances SA’s tolerance, provide theoretical references for further studies concerning decryption molecular mechanisms improvement management

Pathogenesis-related (PR) proteins are critical defense signaling molecules induced by phytopathogens. They play a vital role in plant's pathways and innate immunity, particularly systemic acquired resistance (SAR) serve as key molecular markers of plant defense. Overexpressing PR genes, such chitinase, thaumatin, glucanase, thionin defensin, either individually or combination, have significantly boosted plants' responses against various pathogens. However, regulating the expression these versatile remain only partially understood. Plant hormones like salicylic acid (SA) jasmonic (JA) known for their well-established roles gene to pathogens other stress conditions. genes interact with components hormonal pathways, including receptors (e.g., NPR1 SA signaling), transcription factors MYC2 JA cis-regulating elements W-box), modulate responses. Recent studies highlighted contributions different immunity interactions process crosstalk, which helps coordinate activation. This review provides comprehensive overview proteins, complexity, crosstalk aiming understand improved pathogen resistance.

NbNAC1 enhances plant immunity against TMV by regulating isochorismate synthase 1 expression and the SA pathway

The Plant Journal, Год журнала: 2025, Номер 121(4)

Опубликована: Фев. 1, 2025

SUMMARY Salicylic acid (SA) plays important roles in plant local and systemic resistance. Isochorismate synthase 1 (ICS1) is a key enzyme SA synthesis. Pathogens infection triggered the ICS1 expression induced production. However, molecular regulation mechanism of against virus remains unclear. Here, we employed genetics physiobiochemical approaches to confirm transcription factor NbNAC1 from Nicotiana benthamiana positive regulator resistance tobacco mosaic (TMV). The pathways NbICS1 can be by TMV infection. Silencing accelerated TMV‐induced oxidative damage increased reactive oxygen species (ROS) It also weakened both decreased , signaling gene NbNPR1 defense‐related genes. effects ‐silencing were restored overexpression or foliar applications. Overexpressing prevented reduced production ROS, enhanced viral pathogen, activated expression, downstream localized nuclear emerged ability transcriptional regulation. ChIP EMSA results indicated that directly binds fragment containing GAAATT motif promoter. Luciferase reporter assays confirmed activates expression. Taken together, our demonstrate critical role immunity through activation

The conformational restriction switch concept has been adopted as a major tool for structural optimization of pharmaceuticals in order to expand the chemical structure scope and improve therapeutic activity against specific proteins. Several 1-aminocyclobutanecarboxylic acid derivatives produced this way exhibited satisfactory antifungal vitro compared with positive control boscalid. In tests revealed that compound A21 had comparable, even higher Rhizoctonia solani (R.s., EC50 = 0.03 mg/L) Botrytis cinerea (B.c., 0.04 than fluxapyroxad 0.02 mg/L; B.c., 0.20 boscalid 0.29 0.42 mg/L). Furthermore, A20 was successfully screened good inhibitory porcine SDH, its IC50 value 3.73 μM, which considerable potency (IC50 3.76 μM). mode action determined using SEM membrane potential research. effects substituent steric hindrance, electrostatic property, hydrophobicity, hydrogen-bond fields on structure–activity relationships were elaborated by reliable models comparative molecular field analysis similarity index analysis. density functional theory simulations, molecule potential, docking also used study probable binding target compounds flexible fragments. results showed scaffold could be lead discovering new succinate dehydrogenase inhibitors.

Metformin blocks BIK1-mediated CPK28 phosphorylation and enhances plant immunity

Journal of Advanced Research, Год журнала: 2024, Номер unknown

Опубликована: Март 1, 2024

Metformin (MET), derived from Galega officinalis, stands as the primary first-line medication for treatment of type 2 diabetes (T2D). Despite its well-documented benefits in mammalian cellular processes, functions and underlying mechanisms plants remain unclear. This study aimed to elucidate MET's role inducing plant immunity investigate associated mechanisms. To impact MET on enhancing immune responses, we conducted assays measuring defense gene expression, reactive oxygen species (ROS) accumulation, mitogen-activated protein kinase (MAPK) phosphorylation, pathogen infection. Additionally, surface plasmon resonance (SPR) microscale thermophoresis (MST) techniques were employed identify targets. Protein-protein interactions analyzed using a luciferase complementation assay co-immunoprecipitation assay. Our findings revealed that boosts disease resistance by activating MAPKs, upregulating expression downstream genes, fortifying ROS burst. CALCIUM-DEPENDENT PROTEIN KINASE 28 (CPK28) was identified target MET. It inhibited interaction between BOTRYTIS-INDUCED 1 (BIK1) CPK28, blocking CPK28 threonine 76 (T76) transphosphorylation BIK1, alleviating negative regulation responses CPK28. Moreover, enhanced tomato, pepper, soybean plants. Collectively, our data suggest enhances BIK1-mediated phosphorylation.
