What mechanisms of microorganisms can cause resistance induction in plants?
Best insight from top research papers
Microorganisms can cause resistance induction in plants through various mechanisms. Beneficial plant growth promoting microorganisms (PGPM) can enhance plant growth, yield, and nutrient uptake, while also exhibiting biological control of plant diseases. These PGPM trigger systemic acquired resistance (SAR) and induced systemic resistance (ISR) in plants, making them more tolerant or resistant to pathogens and insects. SAR is induced by salicylic acid (SA) signaling, resulting in the accumulation of pathogenesis-related proteins (PR proteins). On the other hand, ISR is induced by jasmonic acid (JA) and ethylene (ET) signaling, leading to the activation of NPR1 gene, transcription factors, and callose formation. The rhizo-microflora plays a crucial role in eliciting ISR. Additionally, endophytic microorganisms can protect plants from pathogens by modulating hormone signaling pathways and inducing changes in gene expression, secondary metabolite biosynthesis, and plant defensive proteins.

What are the mechanisms by which bacteria develop resistance to drugs?5 answersBacteria develop resistance to drugs through various mechanisms, including mutation of drug targets, secretion of hydrolases, efflux pump-mediated antibiotic expulsion, alteration/modification of drug targets, quorum sensing, and enzymatic degradation of antibiotics. The misuse of antibiotics provides an ideal environment for bacteria to exchange resistance genes through mutations and gene transfer, leading to antimicrobial resistance. Efflux pumps play a crucial role in bacterial resistance by extruding antibiotics from cells, contributing significantly to drug ineffectiveness. Overuse of antibiotics, extended hospitalization, and unintended prescriptions are major factors driving drug resistance in bacteria, necessitating strict regulations, ethical considerations, and awareness campaigns to combat this global health threat.
How microbial biostimulants induce pathogen resistance via metabolic changes on plants under field conditions?5 answersMicrobial biostimulants induce pathogen resistance in plants under field conditions by triggering metabolic changes and enhancing plant defenses. These biostimulants, such as beneficial microbes, activate induced systemic resistance (ISR) in plants, boosting their ability to resist biotic stresses. Through various mechanisms like the production of enzymes, antimicrobial compounds, and eliciting plant defense responses, microbial bio-control agents play a crucial role in disease suppression and enhancing plant resilience against pathogens. Additionally, symbiotic associations between microorganisms and plant roots stimulate plant growth, nutrient uptake, and protection from environmental stresses, contributing to improved crop production and disease management. Overall, the application of microbial biostimulants in agriculture offers a sustainable and effective approach to enhancing plant health and productivity.
What are the mechanisms of resistance in Klebsiella pneumoniae?4 answersKlebsiella pneumoniae has various mechanisms of resistance. The development of carbapenem and ceftazidime/avibactam resistance is attributed to acquiring blaKPC and blaNDM harboring-plasmids, specific mutations in blaKPC, and porin genes such as ompK35 and ompK36. Tigecycline resistance can be caused by overexpression of efflux pumps, acquiring plasmid-carrying tet (A) variants, and ribosomal protein change. Colistin resistance is associated with specific mutations in chromosomes that result in the cationic substitution of the phosphate groups of lipid A. K. pneumoniae can also acquire antibiotic resistance elements such as plasmids and transposons encoding various β-lactamases and efflux pumps. Mutations in different proteins, including β-lactamases, efflux proteins, outer membrane proteins, gene replication enzymes, protein synthesis complexes, and transcription enzymes, can generate resistance to antibiotics. Biofilm formation is another strategy that facilitates antibiotic resistance. Understanding the antibiotic resistance mechanisms and molecular characteristics of K. pneumoniae is crucial for the design of targeted prevention and control strategies against this pathogen.
What are the mechanisms of antimicrobial drug resistance in plants?5 answersAntimicrobial drug resistance in plants is primarily caused by the repeated and regular use of antibiotics against specific microorganisms, leading to the development of resistance. Plant-derived antimicrobials (PDAs) have been found to effectively treat membrane proteins responsible for antibiotic efflux, and their combination with commercial antibiotics has shown superior antimicrobial activity. Phytochemicals, which are bioactive compounds found in plants, have demonstrated potential antibacterial activities against both sensitive and resistant pathogens through various mechanisms of action. These phytochemicals have also shown synergistic effects when combined with conventional antibiotics. The mechanisms of antimicrobial resistance in plants include point mutations, gene exchange mechanisms, and the ability of plants to confer beneficial attributes over microorganisms. Understanding these mechanisms is crucial for controlling antimicrobial resistance in plants and developing future therapeutic strategies.
How to plants resist pathogen microbes?5 answersPlants resist pathogen microbes through various mechanisms. One mechanism is the use of plant-growth-promoting rhizobacteria (PGPR) that protect plants from soilborne pathogens through antibiosis, lytic enzyme production, and the secretion of 1-aminocyclopropane-1-carboxylate deaminase to decrease ethylene levels. Another mechanism is induced systemic resistance (ISR), where a beneficial microbiome primes the entire plant system for better defense against phytopathogens and pests. Plants also have innate immunity mechanisms such as RNA silencing, translational repression, and autophagy-mediated degradation to defend against viruses. Additionally, the inoculation of plant growth-promoting microorganisms (PGPMs) like Pseudomonas, Bacillus, and Trichoderma can trigger plant defense mechanisms and induce systemic resistance. The plant immune system also involves the detection of pathogen-secreted virulence effectors via intracellular receptors, which can be suppressed by host-adapted microbial pathogens.
What is the causes of bacterial resistance?5 answersBacterial resistance is caused by a variety of factors including overuse and inappropriate prescribing of antibiotics. The broad and indiscriminate use of antibiotics has resulted in selective pressure on bacteria, leading to the development and spread of resistant strains. Other factors that contribute to the emergence and spread of resistant bacteria include the use of antibiotics in agriculture, the lack of novel drugs on the market, and the spread of resistance genes between bacteria. Additionally, poor infection control practices, inadequate hygiene, and substandard antimicrobial stewardship programs in healthcare settings also contribute to the generation and dissemination of antibiotic resistance. Poverty at individual, health system, and national levels further promotes factors such as antimicrobial misuse, prophylactic use, diagnostic imprecision, and interpersonal spread, which contribute to the selection and dissemination of resistant strains.
