With the increase in world population, demography of humans is estimated to be exceeded and it has become a major challenge provide an adequate amount food, feed, agricultural products majorly developing countries. The use chemical fertilizers causes plant grow efficiently rapidly meet food demand. drawbacks using higher quantity or synthetic are environmental pollution, persistent changes soil ecology, physiochemical composition, decreasing productivity cause several health hazards. Climatic factors responsible for enhancing abiotic stress on crops, resulting reduced productivity. There various types biotic like salinity, drought, wind, improper temperature, heavy metals, waterlogging, different weeds phytopathogens bacteria, viruses, fungi, nematodes which attack plants, reducing crop quality. shift toward biofertilizers due all these facts, nutrition through natural processes zinc, potassium phosphorus solubilization, nitrogen fixation, production hormones, siderophore, hydrolytic enzymes protect from pathogens conditions. They that sufficient healthy development fulfill demand increasing population worldwide, eco-friendly economically convenient.

Flavonoid-attracted Aeromonas sp. from the Arabidopsis root microbiome enhances plant dehydration resistance

The ISME Journal, Год журнала: 2022, Номер 16(11), С. 2622 - 2632

Опубликована: Июль 16, 2022

Abstract Flavonoids are stress-inducible metabolites important for plant-microbe interactions. In contrast to their well-known function in initiating rhizobia nodulation legumes, little is known about whether and how flavonoids may contribute plant stress resistance through affecting non-nodulating bacteria. Here we show that broadly the diversity of Arabidopsis root microbiome preferentially attract Aeromonadaceae, which included a cultivable Aeromonas sp. H1 displayed flavonoid-induced chemotaxis with transcriptional enhancement flagellum biogenesis suppression fumarate reduction smooth swims. Strain showed multiple plant-beneficial traits enhanced dehydration resistance, required but not sudden “cry-for-help” upon stress. boosted dehydration-induced H2O2 accumulation guard cells stomatal closure, concomitant synergistic induction jasmonic acid-related regulators resistance. These findings revealed key role flavonoids, underlying mechanism, mediating plant-microbiome interactions including bacteria-enhanced

Plant roots aid the growth and functions of several kinds microorganisms such as plant growth-promoting rhizobacteria, mycorrhizal fungi, endophytic bacteria, actinomycetes, nematodes, protozoans which may impart significant impacts on health growth. soil–microbe interaction is an intricate, continuous, dynamic process that occurs in a distinct zone known rhizosphere. Plants interact with these soil microbes variety ways, including competitive, exploitative, neutral, commensal, symbiotic relationships. Both types were found to have impact community diversity structure rhizosphere, or vice versa. The thought be essential for management quality because it has different biocontrol effects could very advantageous host alter physiology nutrition. composition microbial influenced by type. Besides beneficial microbes, also harbors are detrimental plants, competing nutrients space, causing diseases. Numerous antagonistic activity ability defend plants from soil-borne study microbiome formulating strategies transforming rhizosphere benefit plants. This review pays special emphasis populations how they influence growth, nutrient acquisition, inter-relationships between stress resistance, carbon sequestration, phytoremediation.

In the rhizosphere, activities within all processes and functions are primarily influenced by plant roots, microorganisms present in interactions between roots microorganisms. The a dynamic zone surrounding provides an ideal environment for diverse microbial community, which significantly shapes growth development. Microbial activity rhizosphere can promote increasing nutrient availability, influencing hormonal signaling, repelling or outcompeting pathogenic strains. Understanding associations soil has potential to revolutionize crop yields, improve productivity, minimize reliance on chemical fertilizers, sustainable technologies. microbiome could play vital role next green revolution contribute eco-friendly agriculture. However, there still knowledge gaps concerning root-environment interactions, particularly regarding Advances metabolomics have helped understand communication plants biota, yet challenges persist. This article overview of latest advancements comprehending interplay microbes, been shown impact crucial factors such as growth, gene expression, absorption, pest disease resistance, alleviation abiotic stress. By improving these aspects, agriculture practices be implemented increase overall productivity ecosystems.

Co‐evolution within the plant holobiont drives host performance

EMBO Reports, Год журнала: 2023, Номер 24(9)

Опубликована: Июль 20, 2023

Plants interact with a diversity of microorganisms that influence their growth and resilience, they can therefore be considered as ecological entities, namely "plant holobionts," rather than singular organisms. In plant holobiont, the assembly above- belowground microbiota is ruled by host, microbial, environmental factors. Upon microorganism perception, plants activate immune signaling resulting in secretion factors modulate composition. Additionally, metabolic interdependencies antagonism between microbes are driving forces for community assemblies. We argue complex plant-microbe intermicrobial interactions have been selected during evolution may promote survival fitness associated holobionts. As part this process, evolved metabolite-mediated strategies to selectively recruit beneficial microbiota. Some these members show host-adaptation, from which mutualism rapidly arise. also co-evolved antagonistic activities restrict proliferation high pathogenic potential prevent disease development. Co-evolution within holobionts thus ultimately drives performance.

Plant health is necessary for food security, which a key determinant of secure and sustainable production systems. Deficiency soil nutrients invasion plant pathogens or insects are the main destroyers world’s production. Synthetic fertilizers chemical-based pesticides frequently employed to combat problems. However, these have negative impacts on microbial ecosystems ecosystem functioning. Rhizosphere microorganisms demonstrated their potency improve manage encourage growth, resulting in increased yield quality by converting organic inorganic substances around rhizosphere zone into available nutrients. Besides regulating nutrient availability growth enhancement, rhizobacteria fungi can restrict that cause disease secreting inhibitory chemicals boosting immunity pests pathogens. Thus, viewed as viable, alluring economic approaches agriculture biofertilizers biopesticides. This review provides an overview role inducing defenses.
