Tobacco (Nicotiana tabacum) black shank disease, caused by Phytophthora nicotianae, is a significant threat to tobacco crops, leading severe economic losses. Prolonged use of agrochemicals control this disease has prompted the exploration eco-friendly biological strategies. This study investigated effects Trichoderma harzianum, biocontrol agent, on N. tabacum in comparison P. focusing growth, biomass, root morphology and anatomy, hormonal changes, osmotic regulation. T. harzianum significantly enhanced plant biomass accumulation, system development, physiological attributes such as photosynthetic pigment levels antioxidant enzyme activity. In contrast, nicotianae negatively impacted these parameters, inhibiting growth function. Notably, increased proline content induced resistance mechanisms, mitigating stress promoting overall health. These findings highlight potential sustainable solution for managing while improving crop productivity.

Microbiome-mediated plant disease resistance: recent advances and future directions

Journal of General Plant Pathology, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 17, 2024

Abstract Plant pathogens cause plant diseases that significantly decrease crop yields, posing a serious threat to global food security. While disease resistance has traditionally been understood as the trait determined by innate immune system and pathogen virulence system, recent research underscores pivotal role of microbiome in resistance. Plant-associated microbiomes confer protection against through direct inhibition, resource competition, activation responses. Agricultural practices such rotation, intercropping, disease-resistant breeding, biocontrol, organic farming modulate microbiomes, thereby influencing This review synthesizes latest advancements understanding intricate interactions among plants, pathogens, microbiomes. We emphasize need for in-depth mechanistic studies linking agricultural dynamics propose future directions leverage sustainable agriculture.

Mitigating climate change in soil ecosystems involves complex plant and microbial processes regulating carbon pools flows. Here, we advocate for the use of microbiome interventions to help increase stocks curb greenhouse gas emissions from managed soils. Direct include introduction strains, consortia, phage, transplants, whereas indirect managing conditions or additives modulate community composition its activities. Approaches using microbially catalyzed increasing inputs plants, promoting organic matter (SOM) formation, reducing SOM turnover production diverse gases. Marginal degraded soils may provide greatest opportunities enhancing global stocks. Among many knowledge gaps this field, crucial influencing transformation plant-derived into identity microbes activities impacting transformation. As a critical step forward, encourage broadening current widespread screening potentially beneficial microorganisms encompass functions relevant stimulating Moreover, developing these interventions, must consider potential ecological ramifications uncertainties, such as incurred by homogenous inoculants need site-specificity given extreme variation among habitats. Incentivization implementation at large spatial scales could effectively harness increases stocks, helping mitigate impacts change.

Published: Jan. 10, 2025

Abstract Abiotic and biotic soil properties are strong predictors of plant yield globally 1–5 , but they become unreliable over large areas when health is threatened by pathogen 6–8 . Here we present a novel approach to predict based on spatiotemporal changes in chemical biological properties. We first demonstrate that consistently respond environmental change (organic fertilization) regardless the type or geographical origin.

ABSTRACT Afforestation is increasingly recognized as a critical strategy to restore ecosystems and enhance biodiversity on post‐agricultural landscapes. However, agricultural legacies, such altered soil structure, nutrient imbalances, depleted microbial diversity, can slow down forest establishment or cause deviate from expected successional trajectories. In this opinion paper, we explore the potential of inoculations tool overcome these challenges by introducing beneficial communities that accelerate ecosystem recovery development. Restoring crucial aspect process drives broader functionality resilience. We highlight need carefully consider type timing ensure compatibility between inoculum recipient site characteristics optimize introduced species. While tree productivity often central focus afforestation efforts, restoration biodiversity, which will also contribute increased ecosystem‐level functions, should be priority for long‐term Agricultural legacies add complexities process, creating unique addressed in planning.
