The fungi species dwelling in the rhizosphere of crop plants, revealing functions that endeavor sustainability are commonly referred to as ‘plant-growth-promoting fungi’ (PGPF). They biotic inducers provide benefits and carry out important agricultural sustainability. problem encountered system nowadays is how meet population demand based on yield protection without putting environment human animal health at risk production. PGPF including Trichoderma spp., Gliocladium virens, Penicillium digitatum, Aspergillus flavus, Actinomucor elegans, Podospora bulbillosa, Arbuscular mycorrhizal fungi, etc., have proven their ecofriendly nature ameliorate production crops by improving growth shoots roots germination seeds, chlorophyll for photosynthesis, abundant crops. PGPF’s potential mode action follows: mineralization major minor elements required support plants’ productivity. In addition, produce phytohormones, induced resistance, defense-related enzymes inhibit or eradicate invasion pathogenic microbes, other words, help plants while encountering stress.

Decoding Plant–Pathogen Interactions: A Comprehensive Exploration of Effector–Plant Transcription Factor Dynamics

Molecular Plant Pathology, Journal Year: 2025, Volume and Issue: 26(1)

Published: Jan. 1, 2025

ABSTRACT In the coevolutionary process between plant pathogens and hosts, pathogen effectors, primarily proteinaceous, engage in interactions with host proteins, such as transcription factors (TFs), during infection process. This review delves into intricate interplay TFs a key aspect prolonged complex battle plants pathogens. Effectors strategically manipulate using diverse tactics. These include modulating activity of TFs, influencing their incorporation multimeric complexes, directly changing TF expression levels, promoting degradation via ubiquitin‐proteasome system, inducing subcellular relocalization. The systematically presents documented interactions, elucidating mechanisms profound impact on host–pathogen dynamics. It emphasises central role defence investigates convergent evolution effectors targeting TFs. By providing this overview, we offer valuable insights dynamic interaction landscape suggest potential directions for future research.

Published: Oct. 9, 2022

There is an array of pathogenic fungi in the natural environment plants, which produce some molecules including pathogen-associated molecular patterns (PAMPs) and effectors during infection. These molecules, can be recognized by plant specific receptors to activate immunity, PTI (PAMP-triggered immunity) ETI (effector-triggered immunity), are called elicitors. Undoubtedly, identification novel fungal elicitors their comprehensive understanding about elicitor-triggered immunity will great significance effectively control diseases. Great progress has occurred especially signaling pathways ETI, recent years. Here, advances summarized important contribution enlightenment disease also discussed.

Manipulation of plant metabolism by pathogen effectors: more than just food

FEMS Microbiology Reviews, Journal Year: 2023, Volume and Issue: 47(2)

Published: Feb. 24, 2023

Abstract To successfully infect plants, pathogens secrete effector proteins to the plant apoplast or inside cells, where they suppress immunity interfere with other cellular processes facilitate infection. Plant metabolism is crucial for most and plays a key role in defense against pathogens, making it major target pathogen effectors. Effector manipulate host provide nutrients indirectly chemical responses. Recent studies have shown that also utilize effectors shape microbiota composition by altering concentration of certain metabolites. Here, we summarize current knowledge on manipulation We discuss what remains unknown regarding

Plant Defense Responses to Insect Herbivores Through Molecular Signaling, Secondary Metabolites, and Associated Epigenetic Regulation

Plant-Environment Interactions, Journal Year: 2025, Volume and Issue: 6(1)

Published: Feb. 1, 2025

ABSTRACT Over millions of years interactions, plants have developed complex defense mechanisms to counteract diverse insect herbivory strategies. These defenses encompass morphological, biochemical, and molecular adaptations that mitigate the impacts herbivore attacks. Physical barriers, such as spines, trichomes, cuticle layers, deter herbivores, while biochemical include production secondary metabolites volatile organic compounds (VOCs). The initial step in plant's involves sensing mechanical damage chemical cues, including oral secretions herbivore‐induced VOCs. This triggers changes plasma membrane potential driven by ion fluxes across plant cell membranes, activating signal transduction pathways. Key hormonal mediators, jasmonic acid, salicylic ethylene, orchestrate downstream responses, VOC release biosynthesis. review provides a comprehensive analysis responses herbivory, emphasizing early late mechanisms, encompassing physical cascades, synthesis, phytohormone signaling, epigenetic regulation.

Impact of Nutrient Stress on Plant Disease Resistance

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(4), P. 1780 - 1780

Published: Feb. 19, 2025

Plants are constantly exposed to abiotic and biotic stresses that seriously affect crop yield quality. A coordinated regulation of plant responses combined abiotic/biotic requires crosstalk between signaling pathways initiated by each stressor. Interconnected further finetune stress allow the respond such effectively. The nutritional status might influence disease resistance strengthening or weakening immune responses, as well through modulation pathogenicity program in pathogen. Here, we discuss advances our understanding interactions nutrient stress, deficiency excess, context current agricultural practices. introduction chemical fertilizers pesticides was a major component Green Revolution 1960s greatly boosted production. However, massive application agrochemicals also has adverse consequences on environment animal/human health. Therefore, an in-depth connections caused overfertilization (or low bioavailability nutrients) is timely novel field research with important implications for control species.

Pathogens must precisely tailor their gene expression to cause infection. However, a signaling cascade from host signal effector production has remained elusive for metazoan pathogens. Here, we show that plants contain molecular signals, termed effectostimulins, activate the first identified regulator of plant-parasitic nematode effectors. SUGR-1 directly binds promoters, and is central transcriptional network activates 58 genes. Importantly, demonstrate downregulation sugr-1 inhibits parasitism, underlining as valuable target crop protection food security.
