Biocontrol of plant parasitic nematodes by bacteria and fungi: a multi-omics approach for the exploration of novel nematicides in sustainable agriculture

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: July 26, 2024

Plant parasitic nematodes (PPNs) pose a significant threat to global crop productivity, causing an estimated annual loss of US $157 billion in the agriculture industry. While synthetic chemical nematicides can effectively control PPNs, their overuse has detrimental effects on human health and environment. Biocontrol agents (BCAs), such as bacteria fungi rhizosphere, are safe promising alternatives for PPNs control. These BCAs interact with plant roots produce extracellular enzymes, secondary metabolites, toxins, volatile organic compounds (VOCs) suppress nematodes. root exudates also play crucial role attracting beneficial microbes toward infested roots. The complex interaction between plants rhizosphere against is mostly untapped which opens new avenues discovering novel through multi-omics techniques. Advanced omics approaches, including metagenomics, transcriptomics, proteomics, metabolomics, have led discovery nematicidal compounds. This review summarizes status bacterial fungal biocontrol strategies mechanisms importance omics-based approaches exploration future directions addressed. highlighted potential significance techniques ensure sustainable agriculture.

Balancing Nature and Nurture: The Role of Biocontrol Agents in Shaping Plant Microbiomes for Sustainable Agriculture

Microorganisms, Journal Year: 2025, Volume and Issue: 13(2), P. 323 - 323

Published: Feb. 2, 2025

Microbial communities in the plant environment are highly dynamic, with bacterial populations rapidly responding to changes. Numerous studies have examined how both inherent characteristics and environmental factors shape plant-associated microbiota. These determine which thrive they interact plants; certain conditions favor beneficial bacteria, others support pathogens. In this mini-review, we focus on an additional factor influencing microbiomes their surrounding environments: use of biocontrol agents. The increasing application microbial inoculants metabolites as strategies agriculture has created a critical knowledge gap about effects introducing non-native species into natural ecosystems. inoculation plants environments exogenous microorganisms potential alter community diversity composition, presenting opportunities challenges for sustainable agricultural practices.
