Climate-resilient, low-input crops: integrating stress biology and microbiome-enabled nutrient efficiency

Global agriculture faces the unprecedented dual challenge of increasing crop production to feed a growing population while mitigating environmental impacts and adapting to climate change. Low input agricultural systems, which minimize synthetic fertilizers and pesticides, rely heavily on natural soil processes and complex plant microbe interactions to maintain productivity. As climate induced abiotic stresses such as drought, extreme temperatures, and salinity become more frequent, understanding how crops naturally navigate these bottlenecks is critical. Recent advancements in multi-omics and microbial ecology have illuminated the powerful role of the plant microbiome in buffering environmental stress and unlocking vital soil nutrients.This topic aims to explore the ecological pathways and mechanisms by which crops maintain resilience and productivity in low input Agricultural systems. We specifically seek to integrate the fields of plant stress biology and microbiome mediated nutrient acquisition. By bridging these two disciplines, we hope to highlight recent advances in how beneficial microbes (such as mycorrhizal fungi and plant growth promoting rhizobacteria) enhance crop tolerance to climate induced abiotic stresses while simultaneously improving the efficiency of nutrient uptake. The ultimate goal is to synthesize current knowledge to inform future breeding programs, bio-inoculant development, sustainable agronomic practices, and policies that rely on biological synergies rather than increased chemical inputs.Research, Reviews, and Mini-Reviews that address the physiological, genetic, and ecological dynamics of climate resilient crops.
