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.

Abstract Rapid industrialization, modern farming practices, and other human activities are contributing significant amounts of harmful heavy metals to the environment. These can accumulate magnify through food chains, posing substantial risks health. Recognizing global environmental threat its health implications, researchers have developed cutting-edge methods address metal contamination. Phytoremediation stands out as foremost method, offering effectiveness suitability. Combining plant growth-promoting rhizobacteria (PGPR) with phytoremediation be a viable option for minimizing PGPR enhances growth aids in cleanup chemical synthesis, secretion chelating agents, redox reactions, acidification. This review conducted comprehensive online search across peer-reviewed electronic databases using specific keywords related phytoremediation. included 129 relevant articles initially identified 187 outcomes were represented schematic sketches in-depth tables.

ABSTRACT This comprehensive review examined the intricate relationship between climate change and rye ( Secale cereale L.) production, focusing on multifaceted challenges opportunities posed by changing environmental conditions. Rye is a versatile cereal crop cultivated in temperate regions known for its resilience adaptability to adverse growing However, as global temperatures atmospheric CO 2 concentrations rise, effects of growth, yield grain quality become increasingly apparent. In this review, we summarised recent research findings various aspects production under change, factors such temperature (e.g., increasing temperature) resilience, viability face ongoing challenges, altered rainfall patterns (changing distributions with decreasing spring early summer months well heavy events), biotic stress, agronomic practices greenhouse gas emissions. Exploring dynamic interplay among soil quality, stressors plant–microbe interactions reveals insights into response changes. These shape complex dynamics that influence adaptation evolving Implications food security, agricultural sustainability future directions are also discussed, highlighting urgent need adaptive strategies ensure challenges.
