ROOTEX-C · From Wild to Domesticated: How do root traits and microbial communities affect soil carbon stabilization in cropping systems?

Domestication resulted in a loss of crop diversity, and greater susceptibility to biotic and abiotic stressors. But did this transition to domesticated varieties also influence soil carbon (C) stabilization pathways? To address this question ROOTEX-C will bring together a multidisciplinary team with expertise in plant physiology, microbiology, biogeochemistry, and soil science. The aim is to investigate how belowground plant traits, such as root architecture and exudation patterns, interact with microbial communities and influence soil C stabilization across different crop domestication statuses. By employing cutting-edge methodologies, including metabolomics, metagenomics, stable isotope probing, and novel methods for estimating microbial carbon use efficiency (CUE), ROOTEX-C aims to significantly advance our mechanistic understanding of plant-soil C processes and gain insights into the effects of crop domestication on plant belowground traits. Project findings could ultimately inform crop breeding programs and agronomic practices that seek to enhance soil C contributing to both global food security and climate change mitigation. Beyond its scientific contributions, this project is pivotal for the fellow's professional development.
