Drought stress mitigation through bioengineering of microbes and crop varieties for sustainable agriculture and food security

Current Research in Microbial Sciences, Journal Year: 2024, Volume and Issue: 7, P. 100285 - 100285

Climate change and agriculture are intrinsically connected sudden changes in climatic conditions adversely impact global food production security. The climate change-linked abiotic stressors like drought high temperatures resulting crop failure. most severe stress significantly affect the stomatal closure, of reactive oxygen species, transpiration, photosynthesis or other physiological processes plant morphology, growth yield. Therefore, there is an exigent need for cost effective eco-friendly modern technologies to induce tolerance plants leading climate-adapted sustainable agricultural practices sustained production. Among many options being pursued this regard, use promoting microbes (PGPMs) approach promote resilience better productivity. These PGPMs confer resistance via various direct indirect mechanisms including antioxidants, enzymes, exopolysaccharides, modulation phytohormones level, osmotic adjustment by inducing accumulation sugars, along with increases nutrients, water uptake photosynthetic pigments. However, several technological ecological challenges limit their sometimes treatment beneficial fails produce desired results under field conditions. Thus, development synthetic microbial communities host mediated microbiome engineering transgenic capacity express traits may survival present review critically assesses research evidence on potentials genes as develop resilient increased Effective collaboration among scientific communities, policymakers regulatory agencies needed create strong frameworks that both regulate utilization agriculture.

Smart Mixture Design Can Steer the Fate of Root‐Derived Carbon Into Mineral‐Associated and Particulate Organic Matter in Intensively Managed Grasslands

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

Species choice and richness in intensively managed grassland mixtures regulate soil carbon (C) input via rhizodeposition, with potential consequences for long-term organic storage. Based on a field trial different grass-legume-forb mixtures, we removed roots from the soil, which was then subjected to particle-size fractionation trace fresh (net C rhizodeposition) into particulate matter (POM) mineral-associated (MAOM). We related these fractions root traits. Using multiple-pulse 13C-CO2-labeling, captured net formation of (MAOC) (POC) at end growing season. Pure stand perennial ryegrass (Lolium perenne) had higher quantities rhizodeposited allocated MAOC POC (0.21 0.13 g kg-1 dry respectively) compared (ranging 0.10 0.12 0.05 0.06 POC). However, proportion (%MAOC relation that legumes. did not affect quantity or POC, nor %MAOC. The were positively associated length. In contrast, %MAOC diameter lower C:N ratio. Despite legumes, main driver total amount rhizodeposition. These results highlight importance legumes rhizodeposition high length increasing both quantities. Our study shows how plant community design can be used increase and/or facilitate By revealing traits behind relationships between communities formation, provide guide species selection grasslands mitigate climate change.

Organic carbon stocks in weathered bedrock—Establishing the soil parent material as a new horizon in soil carbon research

Vadose Zone Journal, Journal Year: 2025, Volume and Issue: 24(2)

Published: March 1, 2025

Abstract Soil organic carbon is essential for sustaining soil health and functioning achieving the United Nations Sustainable Development Goals. However, research to date has focused predominantly on surface horizons of soil, with fewer studies accounting stored down whole profile. Rarer still are assessments (OC) in parent materials, spite their pervasive presence beneath almost all profiles. As a result, our understanding about storage, functioning, long‐term stability OC within materials sparse. This exacerbates challenge maximizing sequestration Net Zero Carbon targets that require, first instance, holistic account pools processes, including those take place across transition between soils materials. study aims establish foundation an evidence base by comparing stocks measured agricultural profiles associated Sampling saprolite (i.e., weathered rock) was conducted three lithologies Kingdom, thermogravimetric analysis used determine both total content its relative labile or recalcitrant fractions). were statistically similar overlying especially case shallow where effective rooting depth crops. The ratios indicated persistent but when close land surface. These findings underscore importance opens up new opportunities design strategies enhance material zone.
